norton's Common client application, central service that susses out how to operate the main norton stuff which can be tricky in a multi user environment. For example 2 users may be logged on ( say using fast user switching is one way ) And two NAVS are running on two different taskbars, There are Not really two NAVS but just one CCapp controlling the lot... To control the lot independant of user's or before logon you must be a service :) .... Its apparent high CPU usage can therefore be there antivirus or other norton process chugging away doing their job ... allow access for updates etc.  See also: Link Link   Jason

When we did an uninstall of Norton Internet Security 2003, upon reboot of our laptop, we started receiving and error msg indicating that symstore.dll could not be found. The ccapp.exe was still trying to startup.   Jerry
Very Problematic with NAV 2005 & WIN XP. I keep having to uninstall/re-install NAV2005 because on bootup the WIN Install Wizard pops up as though trying to install a program and then NAV2005 auto pops up and says that it does not support the repair feature and I must uninstall/re-install.   Susanne Gyasi
Scan Disk will not run nor will Solitary or freecell. I do a Ctrl-Alt-Delete. And then click on ccapp and close the program. Then I run scan disk or play game . To go out on the web I reboot the computer and go on line.   RedOak21
I get a kick out of the people, who say its uses a lot of memory on my system, in security task manager it shows this process using 0% (zero percent) man hold on thats a lot of memory. It should only use memory when its in use.  See also: Link   Chrispixx The Great
ccApp.exe is the common hosting application that is used by both NAV and NIS. It calls the different program features in NAV and NIS. For example, in NAV, if Auto-Protect and Email Scanning are enabled, then ccApp.exe makes sure that those programs are running. If ccApp is disabled, then Auto-Protect and Email Scanning will not run.  See also: Link   oceanMan
I thought I would come back and add the information that Symantec gave me on my problem. In my case none of the below site helped. My problem is CcApp . It is a shame that when you disable their program (Norton) that it doesnot stop this program also from running in the background.  See also: Link Link Link   RedOak21
Part of NAV... problem is is that it is now running my CPU at 100% util... and it is stuck there... even after reboots. This happened also once with their Norton Security product.... once again, Symantec crapware strikes again!   Ben
It started to become a problem the day I installed Norton Internet Security 2005 (had not used NIS before). It keeps locking up Outlook, and every time I try to reboot it seems ccApp is hanging and not responding.   Simon

I had this problem and it drove me crazy trying to figure what was going on. I eventually determined that if you have the task bar at the bottom of the screen, the ccapp is not a problem. When you drag the task bar to the top of your screen, the problem returns. Strange, but true. Poor programming on someone's part.   John B
it and eventmgr.exe hog up to 85% of my 1.2GHz machine for minutes at a time. Intolerable! Symantec should fix this immediately, or i'm leaving them!   plusaf
Central to functioning of Norton AntiVirus, Personal Firewall, Internet Security. Takes 44MB RAM under WinXP Pro, but 0% CPU - unless you are constantly running e-mail like Outlook (why don't you exit??) or spending all your time on-line such as with role-playing or streaming media. Better safe than sorry.   Stephen

It's an essential application (part of Symantec Norton Internet Security 2004) that works to auto-protect your computer. I agree with previous comments that it slows down your computer and uses a lot of virtual memory. I didn't find this too problematic when running a single program, but multi-tasking can be slow. I tend to disable Norton AV sometimes anyway to speed things up. I never drop my firewall though.   Russ

NAV file running in the background - constantly. Eats resources, especially with iTunes running.   Mikkel
it is your autoprotect function. The problems listed are not because of this, they are because people don't know how to set up Norton or Windows. The issue with Norton trying to reinstall and saying it does not support the repair feature is caused by moving the start menu shortcuts or deleting them, not by this app.  See also: Link   god
Norton's all purpose event handler, very sloppy. Their auto-protect has always sucked, just shut it off and it won't use too much memory. To prevent more memory leak also scan only incoming mail, Norton always has problems when both enabled, no need to scan both direction anyways.  See also: Link

ccApp is more than a memory hog as discussed at http://www.neuber.com/taskmanager/process/ccapp.exe.html.

It belongs with norton.If you have Norton AV it needs to run so it can support Norton. If you like NAV then leave it alone. Its a side pusher to support the emails. If your having problems with it contact Norton. It could be that a virus attached itself to ccApp.exe via back door. If you can Get Spy sweeper and run it to check for any hijackers, ccApp is a vunerable entry because it has no HKEY-Root stabilty. By the way spy sweeper would be a great investment its probably the best out there.  See also: Link   bluejay

Symantec accept that this file is necessary and yet do nothing to improve the CPU maxing problems, but go to lengths to say tough if you want the anti virus to run - garbage, I want my subscription fee refunded!   Kaz H
It is a part of Norton Antivirus and Firewall. It renders both of my PCs useless: Windows 2000 and XP home. The XP crashes all the time and the 2000 is so slow and then it crashes. It is a legal app and it is not dangerous. It just renders your computer useless, so useless that if you had a virus you wouldn't know it. Also, ccapp crashes when Antivirus or the Firewall go to so LiveUpdate to get their virus definitions or when any other scheduled program goes out to the Internet (such as Microsoft Updates).   Ivana

I installed NIS2005 on XP a month ago. Recently the Windows shutdown process became extremely slow (5 minutes or longer). And it always started with closing CCApp.exe.

I hate it because it takes much memory and i get error message when i shut down computer   Oskars
This program conflicts with outlook. Think it has something to do with FW not accepting automatic checks for new e-mails when the screensaver is on. The problem has not occured when I'm working on the machine, but suddenly the cabinet fan start up at full speed. All progam are reported as Running, but in the Process window ccApp.exe is showing constant use of 50% of CPU, and use more than 55' kb memory. Can't kill the process, and when I shut down PC, ccApp.exe is not responding. I'll throw in an hour in fixing this. If not solved, NIS will be repaced by Zonelabs ZoneAlarm.   bts234

This program took up approx 96% of my memory... which is pretty inconvenient (keep in mind it happened after running a virus scan or two).

I have a new windows XP computer. In some cases I can't get it to shut down. It seems that ccApp in some cases is still running. I think my inability to shutdown is probably due to ccApp. If this is the case, I will probably stop using norton antivirus.   Pete M
Extremely annoying - it causes Outlook Express to malfunction every time I use it. I will not buy another Norton product, period.

I've been removing NAV from customer's and friend's computers for several years now. They jump for joy at the speed increase. Then, when appropriate, I install AVG from Grisoft (free) and there is no detectable slowing.  
Crap. 100% cpu. Trouble on shutdown. Computer basically at a standstill.   Who Cares
Part of Norton Internet Security (Anit spam, Virus and firewall). I have reason to believe it causes my Outlook to run very slowly when opening mail and trying to reply. I also think it affects how I attach files. During log off and shut down it always hangs and has to be closed manually.   Norm
I put the process to a low priority so that my other applications can run. Otherwise, ccApp uses 97% of my cpu time for no reason.   JJ
needed for real time virus scanning   John Tallet
My system slowed down to where CCAPP.EXE was bringing my Centrino 1.7 Mhz CPU to a standstill for as long as 5 minutes. Uninstalling and reinstalling NIS completely solved the problem. Only downside is NIS has to relearn all my specific allows and not allows.  
It is not a Windows feature as such, but it is part of Norton Security products. Removing or de-activating it will disable your virus monitoring program, therefore allowing virus-infected files to slip through un-detected. Naturally, if a program is protecting your computer from incoming viruses, it is going to use some memory and bandwidth during it's scans.   Jon
It's completely harmless and runs seamlessly in the background.

my firewall catch it sending emails ,why does it need to send an email! its enabled on my pc but i removed access to internet   Somnus
I agree that it annoyingly slows down XP restart time. Shutdown time slowed down anywhere from 5-15 minutes in my case. I disabled NIS firewall and re-enabled windows SP2 firewall and now it shuts down in about 3-7 seconds. Fixed my problem so there a good chance that will fix yours   Ken
Agreed with bluejay. Add SpyWeeper to yout computer, and you will have less problem. When you have traces of Norton file in your computer after uninstalltion, you need to clear off this file in the misconfig. When that is done, the next installation will ensure a smooth installtion for your NAV and other Symanctc program. the perception here is that Symantec products is too cumbersome and takes you on a merry-go-round on uninstalltion, and latch on to your system for no apparent reason.   choong
IT definatly belongs to Norton Anti Virus, but right now it,s ruining my system. At startup something goes wrong with the app. which prevents me from using the taskbar, start menu or anything put on them. Only via the desktop can i use files and folders. When shutting down the computer it sticks to the 'saving settings screen' and thats it. Re-install worked for only two days before the problem restarted. trying to find out what the cause is.   whistle
Disable Auto Protect and email protection in NAV. Most ISPs have mail scanners and Autoprotect just slows the computer. At one time, had three viruses and Auto protect didn't even think they were viruses, even with up to date defs! Disable Auto protect, e-mail scan (in and out) and then remove startup entry in registry. Do NOT DELETE the file, just the reg entry! required for manual scans too.  
Spybot says it's a worm. I've installed Norton AV twice in the last two months on a clean computer and it shows up right off the bat. Must be part of Norton. Win XP hangs sometimes when I log off. I don't seem to have a problem w/ memory usage. I can live with it.   Chris N.
No problems for 11 months, now it shuts down my OE6 connection to server and also its Auto protect and email scanning by itself. have to restart PC every time for e-mail to autoconnect with server and work. No issues when not using my e-mail first.   Rob
Yes it's required for Norton, but it uses sooo much memory sooo often it brings the computor to a halt! It is so poor that you will turn-off Norton (but then ccApp still runs anyway!) Ok it tries to stop viruses, but I need to use my PC as well!   BlondeBimbo
When the pc is just turned on, the ccapp.exe file has a normal reading of 0-1%. Once I send an email, the ccApp.exe reading sky rockets to a 97-99% and stays at that reading until I either end the process or restart the pc.   Pukka
IS NIS app, (Much better than SP2 firewall) But on occasion, say when several remote requests come in, will start eating up virtual memory. It sucks, I know, but would you rather have your computer naked to the web?   Project: Bluebird
just for gigles why dont u try...... ACE utilitys it is great on xp cleans up registry defrags it well and has a lot of other great utilitys that workedas well as any app ive ever used and should speed up slow pc s   c.o.jones
Using XP Pro, and this program is causing me a Runtime Error that's stopping me from using MS Outlook to send/receive mail. Nasty little thing. Might go for something other than NAV.   Bessie
sure glad i dont have the problems of some of theese people dosn't really cause any problems w/ my xp rarely after closing a game but not a problem benefits out weigh the conflicts   braindamage
Should be named ccrap.exe, takes too much memory, slows the PC to a halt, and makes it not worth having Norton. If you need to use your PC do not use Norton, use a better package  
I wish my task manager would let me close ccapp, or any of the Norton's files running, but it says "Operation cannot be completed. Access is denied." WHY!?   Steven
Major pain. Slows PC down drastically, stops responding often, keeps IE from running normally. Stops responding on shutdown and makes startup slow.   Steve
It is a part of Norton Antivirus. If it causes problems, it is due to synergie with other programs and not CCAPP.EXE itself   Jens
Its a load a rubbish, I get all the same problems as above. How can Norton get away with selling faulty shit like this?  
Randomly uses 100% CPU utilization while playing games, REAL problematic as it slows my system to a rock.   Syx
It's pure crap. Uses 99% of the CPU power for some stupid ass memory leak or loop. Kill it I say.  
pops up when i go to close down my computer which slows it down and takes longer to close up.   Charlotte Whiting
While NAV is checking a file, ccapp.exe uses more CPU. If it's a big file, it takes longer.   Michael
it is impossible to kill (even with the command line taskkill and tasklist)   Vince
On 98 how about going into msconfig and killing it from startup?   Bigred
it destroys the connection to the internal e-mail server   harald

It hogs the CPU!  
CCAPP??? Maybe a better name would be CRAP! CCAPP.EXE is probably the most annyoing problem I have ever encountered. If NORTON is and by the reports I have read is responsible then wouldn't it be in the best interest of everyone to send and keep sending e-mails to NORTON with complaints. Of course we could all threaten to use a different anti-virus but threats don't do much good unless we mean them. I for one will never use Norton again. I refuse to pay $75 or $80 ofr a program that slows my system down and uses up my CPU usage. GOODBYE NORTON!   Ray
ccApp is the per session hosting application. It hosts various plug-in modules that load at startup for Norton AntiVirus (NAV), Norton Internet Security (NIS) and Norton Personal Firewall (NPF). ccApp is a “container” that hosts the various services for each user session. This means that ccApp loads whenever a user logs on. In Windows 2000 and XP this could mean that more than one instance of ccApp runs at a time, depending on the number of users logged on to the computer.   ash
This file is in auto protect of Norton. I called and talked to a tech at Smantec. Because of shut down problems.This is the FIX. 1 Open Norton System works.2 Click on the options on the top.3 Click Norton AntiVirus.4 Then under System in the upper Left,Click on Auto Protect.5 Click on Advanced.6 UNCHECK-scan floppy disk in A: for boot viruses when shutting down.7 Then Click ok.... NO MORE PROBLEMS...   Lyndon
After upgrading to a 64bit Athlon from a 1800+ Athlon, you'd expect an increase in speed opening and closing windows and applications. Oh no, not when your motherboard comes with Norton Internet Security 2005. This significantly reduces system speed to the point of which I ask myself what was the point of upgrading the CPU??? Now going to ditch Norton and return to Mcafee........Norton really sucks!!   Mart
I don't know what to think about it. If I open a web page it takes ages to load, then if I check the Task Manager, cCapp isn't responding. If I try and close cCapp from there, the computer just freezes - some clunking goes on inside and the light on the floppy drive flashes?! I ran a couple of full system scans with NAV (2005) and both times it has detected cCapp as adware (I think).   BlackMagic
Has 'hung' the task bar for a period of time until it suddenly springs back to life and the task bar functions again. Seems to be internet linked and must be doing some kind of 'checking' or something. Also when shutingdown the computer after it has hung because of this I'm asked if I want to 'End Now' ccapp. On restart everything starts agin fine.   Happy Face
wont play nicely with outlook express no matter how closely i follow advice on disabling scanning of outbound mail. chews up 99% of CPU and leaves Outlook Express unusable after i kill ccApp off, so that i have to restart machines to check my email. unbelievably annoying - i wish my employer didnt mandate that i had to have this pos installed   Dale
Very Problematic with NAV 2005 & WIN XP. I keep having to uninstall/re-install NAV2005 because on bootup the WIN Install Wizard pops up as though trying to install a program and then NAV2005 auto pops up and says that it does not support the repair feature and I must uninstall/re-install.   pradeep
Works like it is suppose to, i only have one problem with it, it has to manually shut "ITSELF" down. it hangs my pc from shutting down by like 2-3 seconds, little bit annoying. i would like to know how to alter its shutdown somehow so it doesnt hang my computer from shutting down   Ryan
Every time i try to log off my desktop to get to another or even to shut down it says that it is not responding. Even after i end the task about 50 times I still can't get my computer to shut down. Then I have to shut it off by the switch. I'm switching to McAfee   Knedeepinlif
Something to do with emails - but i can't turn it off - task manager won't allow me to do so. I think it's causing my games to crash to the desktop. Initially I thought that it was a 'directX' problem, but through elimination, its NAV 05 with this $%#@ file.   hotrod
Hogs a lot of memory; slows down system; hangs at shutdown. Won't be renewing my subscription with Norton. Too many really good system security programs that don't hog memory out there to have to put up with it.   Jack
I has a trial version of NIS which ran out and CCAPP still runs, using 99% cpu and it seems to be slowing my pc down alot! Surely it shouldn't be doing anything as norton isn't even activated!   Fragatta
For a reason yet to be identified Outlook is unable to download from 'ic24' email acccount until I have stopped CCAPP from running ... this defeats the purpose of Norton email checker.   AJB
If it uses a lot of resources, it is because your system need that much protection. You probably have spyware trying to phone-home, and ccapp is only doing its job, and a lot of it.   JRBeaman
add page file (ie ram memory) everytime it scans something. calls up from 15mbs, normally at 20-60mbs, my high score is 1.8gb! just log out and login back again if it eats too much  
No solutions apparent. This ridiculous app is hogging 99% of my memory even when no other programs are running. What is it checking? Norton is losing face over this.   BizMgr

I'm no longer able to recieve/send Outlook emails unless I turn Norton off. Before opening emails, I must turn Norton on again to be protected. It knocks me off the Internet at some point EVERY time I'm logged on. I must reboot several times/day. Sucks. My computer experience has been ruined.   Christine
It is part of NIS. Since it uses all of my memory, my applications have nothing, so they lock up. I have shut off the firewall while I am on my computer.   Jan
I noticed it one day when I tried to shut down. It does not play well with others. We run Symbari on the mail servers so basicall mail is scaned twice. Once from the desktop and secondly when in the mail site. Definately hangs up the machine in the morning, but tends to taper off during the day.   GEM

readers! ccapp.exe is from norton antivirus the reason that the error shows up is because of the windows service pack thats plain and simple its nothing big just deal with it and it you disable ccapp.exe then your norton will not run when you restart your computer.  
From what I see here, this must be a part of NAV and NIS, which is what I have. I have noticed lately that my computer will never shut off without first ending ccApp. But a worse problem Ive begun to experience today is that NIS wont let me open Microsoft word. The process just hangs. If I disable NIS, Word opens right up. Then if I try to shut of the computer, it just hangs there with the ccApp end program box, frozen, and I have to manually shut it off with the button.   olivia

Yes, it is necessary for Norton to run. I removed it from autostart and manual system scan would not work. Solution: uninstall Norton and use a different anti-virus program. I loaded AVG 7.1 for a free trial period and like it enough to pay for it after the trial is over. It is only anti-virus, so I rely on LavaSoft's AdAware (completely free) to counter spyware and the firewall built-in to Windows XP Service Pack 2.

it causes xp sp2 to hang on shutdown   proper
It is effectively a system hook. It registers with the OS to recieve info about anything from opening files to sending an e-mail to accessing a web site. When the OS does any of these this Ccapp.exe is notified and Norton antivirus can take appropriate action. The high memory usage is only generaly when doing something although with the large hard disks of today virtual memory is irrelevant coz it only comes into physical memory when in use. If its hanging it is most often caused by not installing windows updates that the antivirus relies on since the antivirus links so closely to the OS.   AlphaGeek

It is obvious that there are two ccapp.exe kind of files. One is safe (ram hogger) used (and required) for NAV & NIS.

Got Antivirus 2006 & XP. There's slowdown & always hangs on windows shutdown. Opening applications on startup takes 10-20 minutes! I wonder: Is Norton using my online connection surreptitiously?

Not dangerous, but it will crash sometimes when shutting your system down. At my PC, it uses 21MB of memory and far less than 1% of CPU, so that's not very much...

Norton Internet Security is a powerful and effective way to prevent most computer viruses. It is a legitimate company, but you may want to check the digital credentials, which may be fake or none existent. You shouldn't have it unless you signed up for it, or your computer came with a pre-paid or trial run. I suggest doing something many others have suggested, which is to turn off all mail applications and switch the outgoing mail protector off. Remember to put it back on when you're done doing whatever or trying to send mail.   DOS Man

Part of Norton antivirus 2006, slows down computer and can cause slow startup and shutdown.   Eric
Vital for auto-protection and email checking..keeps your computer protected from viruses automatically   Phil
After 3 hours of trying to get the fix suggested by norton to work, I fixed it.. I removed Norton, going with AVG Free   cdbest
It is a memory hog. Terrible but necessary if you wish to continue to use the norton programs. You can stop it if you dare.  See also: Link   RVPARKMGR
This app needs to be slapped with a wet kipper. Every time closing down becomes a nonsensical chore. I yawn in the face of Norton and step back to ZoneAlarms firewall. [I think I just heard a whimper of joy from my PC.] If this is an essential part of NIS, then it shows the standard of programming from them, in regard to such a commonplace task, got as far as two plankton trying to make a sandwich :0   liquidgloo
I agree with those who complain about the performance , but don't thind its' dangerous. Just a BIG nusance. I have experienced all the above problems with it.   lp
It cause my WinXp to crash upon start up. I have to disable it via registry. Then after WinXp is running properly. I enable this process. My windows runs fine.   Junlin
the problem with the cpu spiking to 90+% seems to only occur when I had windows firewall turned on in addition to norton. Turned off windows firewall like norton recc'd and the problem went away. I went to symantec auto assisant and got that advice. Also seems to occur if you use any other firewall with norton. I'm posting link to a conflict with zonealarm.  See also: Link   sans-culotte
It is annoying as hell. Anyprogram that is not system vital that gobbles up your cpu constantly and cannot be shutdown normally is a bs program, and considering this is a big security program I find that tripe. MS can only get away with it because they make the OS.. having to uninstall a product and reboots SHOULD NOT have happen. the reason it gets a 2 and not a one because it heated my comp like a mofo doing nothing benificial.   William
It conflicts with a number of MS applications and Operating System programs (MS-XP). MS says Symantec has no solution to this problem.   Chilote
There is also a trojan called ccapp.exe around. NAVs ccapp wants to have an open port - 1030 - and also wants to phone home by sending information via smtp. Symantecs tech support would not answer questions as to why this is needed. NAV2006 has 13 processes that run on XP - totally ridiculous. Ditch the program and get a better one.   Eddie
it happens due to NAV...plz go to symantec.com...on the search page type symnrt.exe.....dowload that file...and run it...it removes the symantec application from the registry....if you remove NAV from add/remove programs it will leave behind the traces of it in the registry.....i tried it and it really helps  See also: Link   sabyasachi c"ty

CCAPP.EXE is in fact part of the Norton Systemworks 2005 antivirus suite of programs, and as such is "probably" not a security risk. Having said that however, it does seem to conflict with some other running processes on the system and will often stop responding, causing a freeze-up of the internet connection and the system as well, requiring a reboot/scandisk/cleanup to repair damages from abandoned programs that were running. I am running WIN98SE with the free version of ZoneLabs ZoneAlarm firewall, instead of a Norton firewall product. I suspect there may be some conflict with ZoneAlarm.   Zoned-Out
Stopps responding every time I try to shut down win xp. irritating. also causes very slow ( 5 minute) shutdown time occasionally.   Tim
Part of Norton AV - causes many, many problems on a variety of systems. Never versions of Nortons are even worse than the old ones. Recommendation: avoid using Norton for your PC security. There are many more effective and more efficient programs available. Norton is often worse than the viruses it's trying to protect you from!   Qualified PC Technician
i still get this message, even after i run norton's live update.   stuart
"ccApp.exe is the common hosting application that is used by both Norton AntiVirus and Norton Internet Security. It calls the different program features in Norton AntiVirus and Norton Internet Security. For example, in Norton AntiVirus, if Auto-Protect and Email Scanning are enabled, then ccApp.exe makes sure that those programs are running. If ccApp is disabled, then Auto-Protect and Email Scanning will not run." I guess it's safe to leave it then : )  See also: Link   Amoebanath
Part of Norton. Uses 99% of my CPU at any given time, and I have a really good computer. Very much a resource hog.  
Causes my PC to hang on shutdown - even ctrl alt delete does not work. Have to switch off or rip out battery....I have Norton as part of BTInternet so probs its fault   Jon Black
Giving me a headache - each time I open Google, a screen pops up stating that there has been an application error involving ccApp.exe   M Patry
Part of the Norton Security Suite. My old computer can't handle everything that the Symantec boys want to run. I don't have top of the line like they do. I have to be offline when my computer boots up so that I have just enough control to disable e-mail scanning by Norton, otherwise my machine is crippled at 100% CPU. With e-mail scan turned off I can use my computer. I'm waiting for my Symantec subscription to expire and then will shop around for smarter, leaner security software.   Tucson
nav file can cause comp to force its close on shutdown only use 10 megs of ram in a world of gigs who cares   Jason
hey lyndon thanks for ur tips...everyone do what lyndon did...disable A: drive scan at boot....no more problems   Macro
CCAPP doesn't seem to have too much of a detrimental effect on my system. Yes it does seem to use a lot of physical and virtual memory, especially since I started using ethernet instead of USB for internet. I have 2GB of RAM anyway. Seems I am luckier than some in that NIS 2006 does not hog my system (touch wood) and my XP SP2 PC shuts down fine 99% of the time.   M
been trying to uninstall NIS 2005 and its so far taken over 1hr 40 mins.... ccApp.exe is at 99%!   BlackMambo
This file has never been reported by any spyware/maleware softwares as infected or dangerous, it just annoys by the error report before rebooting/shutting down   DJA
Make sure you have lots of RAM - a full gigabyte is my recommendation. After I upgraded from 750mB to 1.25gB my problems with cpu hogging and system hangs went away. NAV is a demanding cluster of applications, so bottlenecks in your system can bring on a slump, or a complete halt. By upgrading my system to meet the demands of NAV, all of my applications run smoother and faster, and I can run 24/7 no problems. I stress the need for lots of high-quality RAM with low latency - 2.5 or less. I'm using Kingston's best. It was very hard to afford it, but it made my computer run like a new system.   x8tmc8x
Seems to be spiking CPU usage when logged in via terminal services (remote desktop.) It's probably trying to scan all of the network traffic, which is a lot when using term srv. No other problems with it. Occassionally waits a bit after it's given a stop signal before it actually goes away (causes the 'not responding' dialog to briefly appear,) but this is by design, from what I understand.   Ross
AWAK, it is part of Symantec's less-than-transparent Internet software line. It purposefully hangs on to be the last app closed for our protection. It may appear to hang your computer if you do not have scads of memory; and I mean scads ... anything less than a 1GB is going to appear to be hung for quite a while. Even with 1GB it can take several minutes to complete it's work. The only way it can hang (to my knowledge) is if some app (probably a virus) is trying to outlast it so it can modify your system on the way out. It is clumsy but apparently does the job since I have had no infestations.   Jim
just uninstall NAV and dl Avast, mush better and doesnt cause any system hang-ups or outlook issues   twisted
Periodically freezes up Win XP Pro system by maxing out CPU. Prevents shut down on a regular basis. It became such a nuisance, I had to uninstall NAV 2005 to get rid of it.   Paul
After my computer reboots, it goes normal CPU usage and doesnt lag as much but after a while of using it, it suddenly lags then goes to 100 percent of CPU usage. I have found several traces of spyware but have removed instantly. I don't know how to fix it as everytime i end the process of CCAPP it tells me i can't.   Drake
"Not Responding" appears when shutting down. I followed these steps and computer shuts down properly.  See also: Link  
It is "common client application" and is used in conjunction with a number of Symantec Norton programs, such as Norton AntiSpam or Norton Antivirus.   Beep Star
Good to see others are having the same issue with ccApp at shut down!! Very annoying to say the least! I have XP SP2 and just upgraded to norton 2006 --- what a waste of $$!!   Dano
This file locks itself to the os and then consumes large amounts of memory and then it starts useing all the cycles on my cpu just for a file too download from microsoft   Trc
This file is required for Norton Antivirus but. It is really annoying because some of the programs i run makes it take up 99% of cpu usage. I cant disable it and usualyy cause my computer to crash   CCAPP.exe --- (-.-")
it freezes my computer up and other programs quit responding   suzanne
It is EVIL - No doubt; and so is NAV, Hackers, Microsoft & Computers in general   JJ
It's annoying, sometimes impossible to end, and essentially is a part of Norton Internet Security which was a BIG mistake for me to use as my virus-scanning program. If I could successfully remove it I'd install something else (McAffee perhaps?). Better solution is to by and use an Apple Mac (which I've done).   Dave Saunders
Win98SE OS: It is very tetchy! Even with no e-mail running (I check that only every other day). CCApp.exe is the main reason for virtually all of my system hangs and crashes, it also slows or freezes the system on shutdown.   CobblyWorlds
its chewing through 99 percent of my pc's power. no wonder WoW was lagging...   Danube
CCApp is Common Client application consuming alot of CPU processing at the beginning and when we shut the pc down. As the part of symantec stuff, CCApp will not start burdening our pc if we open a browser (e.g. Mozilla). However it utilizes the physical memory considerably alot as trading off to have it checking incoming file or email.   mohadig
Not harmful but kind of annoying as it takes a lot of memory (about 7 to 10MB) and Windows XP always have to wait for it to shutdown (by force) before Windows itself can shutdown.   Samuel
It has been responsible for the biggest and most damaging computer crashes i have ever experienced, at times causing almost irreversible damage to both my previus and current computer, and as far as i can see serves no purpose, apart from to crash the computer and it does that far too frequently.   Magic Leprechaun
I hate programs like Norton because of their self-importance. I am a gamer (both on and off line) and NAV was constantly interrupting my games with routine reports, and crashing the system through hogging memory and CPU resources. My solution was to change to Avast anti-virus, which not only does the job at least as well, and without the unwanted interruptions, but is also free for home users.   Onymous
I know that every time my computer has a program crash, the culprit is ccapp   partytildawn

I find ccApp.exe makes it impossible to work on large graphic files because is uses so much cpu memory. Sometimes it crashes my Win XP pro computer, and always hangs up on closing. I am using Norton 2007. I disabled ccApp.exe startup in Spybot program and rebooted. Norton didn't load. So I had to go back in Spybot and check it for startup. I will not renew Norton and as soon as I find a good FREEWARE virus software I'm unenstalling Norton.   Cindy Smith
Symantec - Uses massive amounts of cpu all the time. Helped to remove outgoing email scanning now just high cpu when using outlook but still uses high mem. Cannot end process in task manager - "access denied" error msg.   Tess
I agree that it is very resource hungry and very unstable. I have now cancelled my subscription to Norton and got PC cillin. Much more stable much less intrusive as far as system resources are concerned   eciwzz
Eats resources, just like all the other useless processes norton spawns. When trying to pull down email from outlook, my clients thought their system locked up when it stalled at "retrieving message 1 of x" for a long time. Turns out it was stupid norton trying to scan the file as it was being downloaded, slowing everything down to the point where the system had to be restarted. The clients would restart outlook and try again, spawning more instances of the scan resulting in multiple copies running at the same time. Norton is garbage and I can't wait to get my office away from it.   Brandon
Watch out for capp.exe, a trojan that tries to look like it.   Nate
when taskmanger is disabled whats that   AYAZ
I don't even have norton antivirus and it's on my computer. I have symantec or something.   Ted
It is part of Symantec Norton Antivirus, which consumes a vast ammount of system resources. My suggestion is to find an alternative due to the fact that Norton isn't that great anyway.   Stranger
it seriously causes problems in shut down because it doesnt find the floppy drive on searching the computer   AK
I have not found out why I'm getting this error even in idle I get it but if this application is closed down microsoft outlook won't work. I think this is a Norton issue and Norton should fix it.   PG
used for norton antivirus, only problem i've had is that it is a spot viruses will attack repeatedly until you get rid of the virus...   A.F.I. xDxHx
Its hanging the windows xp operating system   Nitin Chagal
this file will, at times, start to take up 99% of my CPU. It will not let me end the process (it tells me access is denied) and the only why I can stop it is to re-boot. I dont even have an active NAV right now and so I cant disable email scanning through NAV (Symantec's advice for this problem) because I need to activate NAV, yet, when I start activating NAV this process pops up and crashes Norton.....I seem to be stuck in a pretty messy cycle here.  
We are a Data recovery Company and have been using ONLY symantecs products to protect us for almost 20 yrs now. ccApp is certainly not malware of any sore, having said that, it is a fact that it does 'appear' to slow down shutdown and on occasions appears to 'hang' As usual in these cases, the culprit is often another task, a conflict or even memory leak. Try to close or unload other background tasks and remove anything unknown. That solution works well for us at Aurora Data Recovery in Sweden.  See also: Link   Sandro
Used for the mail proxy in Norton. Keeps processor at 100%..working it hard. Useless in the big picture since it retards your computer and steals not only processor power but massive amounts of memory. Ditched Norton and now use Avast.com .. my computers are free once again to do their jobs without compeiting for massive amounts of processor time. No virus .. ccApp is dangerous enough in that it steals your computers ability to function at an optimal level and in some cases crashes when logging off or shut down.   Professor Jay
Each time I start up a virus alarm says there is a backdoor trojan: when I shut down ccApp.EXE the alarm screen goes away (sorry for my bad English)   OGMO
Memory Intesive but safe file.   Daniel
it uses my processor work at 100% and really slows everything down immensely   jurgis
Conflict with AVG antivirus will cause ccapp.exe to go to 100% cpu use and prevent outlook from retrieving email. Ccapp.exe does not properly disable when using Norton's interface; must remove startup entry in registry or uninstall product. I rate as dangerous because it is poorly designed and interferes with normal computer operation.   Tim
everyone says its part of symantec, but they dont say why its slowly eating its way through peoples hard drives. its useless for its proper job and is more dangerous than not having an anti virus protection, get rid, soon!!   consty
It's using 100% of my memory, it is in the correct folder and i'm not using any program, WTF! i wont reinstall norton tell me why it's going that crazy for no known reason   F0U
This file is from norton internet security when it crashes ie the end programme pop up the internet will not work and if you wish to get it back write in task manager FILE new task "ccapp.exe" and the internet will work again   LUKE
One way of getting rid of this pesky but not critical issue is to uncheck 'ccApp' in the system config utility dialog bx then 'apply'. Go back and check 'ccApp' then 'apply' again. This works for me -so far. This resolution was as per Norton help desk. Good luck!   avi
Whenever I start my computer, and connect to the internet, I keep getting hundreds, if not thousands of "Symantec Email Proxy" popups. Using a task manager, I found out that if I "stop" ccapp.exe the popups stop. But I'm afraid to send it to the quarantine to stop it for good, because it might me necessary to protect against viruses in my emails. But it's a major pain in the butt.   Macheteman
Also installed by Norton Ghost 10, don't know if its the same with other versions of ghost, but no matter what anybody says, Norton IS is very bad but Ghost is the best in its league  
It's memory resident for security reasons, therefore you need a decent amount of RAM to run with it.. Not checked out Symantecs site but suspect they probably recomend at least 1024k RAM. If you haven't got that switch on, make a cup of coffee, go have a shower,dress and have breakfast then you may be able to log in. Alternatively get MacAfee.   Widget
ccApp.exe is a process required for Symantec's (Spelling?) Norton Anti-Virus and Norton Internet Security to run properly. Takes up 21MB of RAM on my system...but I've had NAV for years, and it works. It's better to have some RAM taken up than to have a virus destroy your computer.   Anon
part of the norton internet security, no danger unless you have a bad computer, it'll slow it down a lot. i don't have any problems.   (none)
This file is part of Norton AntiVirus and Norton Internet Security. If it is not responding during shutdown or restart Norton seems to recommend turning off "Scan floppy disk in A: for boot viruses when shutting down." If it is using a huge amount of CPU usage Norton seems to recommend turning off the "scan outgoing mail" feature.  See also: Link   NB
Well, my experience of late is this little applet ccApp.exe is quite annoying when I want to open anything in MSN for one example. Another annoyance is my CPU gets hit for 100% for a long time. I have had to use the task manager to close this applet down. Of course, this is from Norton 360 which I purchased recently and I am regretting that decision. Days after the installation, my whole computer started to slow down and I started to disable sections of Norton and my computer came back to life. I believe Norton has a serious problem with their products lately --- Beware of Norton Products   debian_duber

on my pc it uses up all the memories, and sometimes crashes my internet explorer. it's good to hear it's norton but they haven't thinked about all the memory it use =/   starnight
ccApp is used by norton but can hang on startup. If you notice that the app is not in your bottom toolbar then it has hung. To fix it just startup notepad, type something it it, don't save the notepad, go to Start Menu and do a Logoff. When it comes up with ccapp not responding end the task and when it goes to close your notepad hit cancel to abort the logoff process. Now you can operate normally and run the NIS config to run Nortan normally. Its a method around the problem but not a fix for it.   Michael
Tip to disable this ccApp.exe file : move it from the Registry\All User\Run keys to the Start Up folder the disable all the entries in Run Key (it basically works with most comercial legitimate anti-virus software) If u dont know how to do it use the XP or Vista Manager trial shareware soft from yamicsoft.com though there are dozens of other pc or tools to do it just in the same way on the internet (not recommended doing it with the win registry edit). Simply deleting that file wont work at all since it will re-start on next systems bootup. Try disabling it first as indicated in this post.   Deletemaface nickname

it may soak up a fair bit of power but it isn't dangerous. it's actually rather safe (norton)   aidz

ever since I installed Norton Antivirus 2006, this CcApp error occurs. It's harmless, but it uses up time and memory. Norton should be more considerate.

it crashes my email; I get it every time that I download/install a program that uses Java runtime. Then I have to uninstall Java afterwards and my email works again. It's a conflict between Norton Internet Security and Java.   Catherine
It's Symantec/Norton garbage, get rid of it and use a REAL AV/security program! The detection rate for symantec products is relatively crappy, the bug rate is incredible. Some version don't even add properly when showing the download size for various updates. Suggest Avira, Eset, or Avast. But before you do that go get the Norton Removal tool to get rid of the Norton junk that norton can't uninstall!!  See also: Link   MrPicky

Running an old system with xp and with Norton anti-virus 2005. From Task manager: CPU usage is at 100%. CCAPP is using all available memory. Browsers are useless. After reading around (on another machine), I decided to uninstall Norton. When I did this, I was able to do a normal shutdown, and when I restarted CCAPP was gone, and the system was really fast - even the browsers.   SteveH
