This is the file which automatic reboot the system and enable svchost.exe file again and again MOhsin
navaspscv.exe is a phone home cookie for norton anti-virus, located in the general index.dat file group folder. any history eraser program will delete it. This 'file' can allow anyone with some 'script' knowhow to easily give you a remote trojan. Norton came with my new computer but i am uninstalling Norton and replacing with Kaspersky Anti-Virus Personal Pro (the best ) brian the webmaster guru
Norton antivirus auto protect - pretty much jus scans open,new,copied files Minion
it occupy too much memory,about 50MB zhang zhonghua

This file is part of Norton Antivirus. It's the Autoprotection-stuff. NAVAPSVR = NortonAntiVirusAutoProtectionSerViCe Cruel Device
It takes a hell of a lot processortime !!!
This service is installed with Norton. Unless you want your Virus Scanner to not function, keep this in Manual.  See also: Link e9racer

i cant remove norton 2003: uninstallation program cant find navapsvc (but it's still present in the task manager's process' list) gibaud
It is supplied and launched by Norton AntiVirus David
This is Norton antivirus autoprotect from what I've learned. But it does about 180,00 I/O reads every time I start my computer and makes it unusable for about 2 minutes before it's done doing whatever it is doing. I would appreciate anyone's input on how to reduce the delay it produces at startup.
slows things down considerably jw

Norton Antivirus,if you are having problems with it being a resource hog then you must have an ancient PC. Any modern PC shouldnt have any problems. I run it on every thing from a 9III 1000 to a Athlon 2600XP and no problems at all. Ardz
eats at CPU - UGH wizkid
norton antivirus and navapsvc.exe in particular simply wont go away. I'm not sure, but I think this is in some mysterious way to blame for a whole lot of problems i've encountered recently, such as not being able to access secure sites.

Norton Antivirus autoprotect. if youre surfing the web, or opening a new exe. for the first time, its a very good idea to have this running. to reduce processor usage, do a full system scan of your computer. if that doesnt work, i cant help you Phil
high cpu utilization 40+% all of the time
It stops the computer from shutting down. Linda
If you want to be protected you keep it, if you don't wan't it's up to you... dinges
Slows down my system considerably, making it unusable for roughly 5 minutes after starting. Max
It seems to eat up CPU, but never release it. Shutting down and rebooting resets it, but, in a week or so, I'll have to shut down and reboot again to move it from using 150meg back to 20 meg. slave
It Crashes XP professional Restore Operation Sanford
navapsvr means Norton Anti Virus Auto Protection Service ,well it takes from 3 to 15 mb of space but it dosen't make any negative effects on a new pc ,1.5 ghz and above ,but sure it slows dramaticlly olders pc
It consumes 70-100% CPU on my NEW PC! Mark
It's eating 24% power from a powerfull dull Xeon 2700. Cue
Bring up task manager and see if photoshopelementsdeviceconnect is running. If it is, end the task and see if navapsvc.exe stops eating up all the cpu time. I stopped photoshopelementsdeviceconnect.exe from running all the time by using msconfig and unchecking it under the services tab. John
Takes 35 % or more of my cpu. Ardz's connection to "modern machine" is bogus. I have an Athlon XP 2700 and I have a problem with the file. Ray
It is approaching 1B I/O Reads on my system and really slowing things down.
When I try to install Norton AntiVirus 2004, I get a screen saying the navapsvc.exe file cannot be found. Why isn't the file on the Norton AntiVirus install disk? Bob
Tremendous waste of resources. Huge consumer. Peter
Pulling cpu resources Malcolm
Part of Nortons bloatware slows fast sytems to slow and cripples slow systems Norton prevents viruses from infecting your system by crippling your system thus rendering it unuseable thus if you cant use your system you cant get infected nice one norton
John, You were absolutely right about the photoshop elements. Good Job! Jason
it kills my processor , i am getting rid of norton bob
hogs my cpu and slows down games James
As John said "Bring up task manager and see if photoshopelementsdeviceconnect is running. If it is, end the task and see if navapsvc.exe stops eating up all the cpu time. I stopped photoshopelementsdeviceconnect.exe from running all the time by using msconfig and unchecking it under the services tab." Wow, I stopped photoshopelementsdeviceconnect and the navapsvc cpu usgae went down to 0% immediately. Amos
Well something is definetly wrong here. Who ever keeps saying that its because its running on an old computer is wrong. When it messes up it messes up. Right now its eating up 30-50 % of my CPU... Norton works fine for some people and others.... becareful getting rid of Norton, it can be troublesome. Don't check their website its a waste of time. I "think" the whole problem happens after a system has become infected. I encountered a virus that was able to turn off the windows firewall and shut down the autoprotect. Norton wasn't able to save its selve from this one. Norton has crapped since. Westergom
It was eating 70something % of my CPU. Granted my CPU is slow by today's standards. Ending the process caused the Norton anti-virus auto-protect to shut off. I noted it because Suddenly my computer was suddenly slower than sh**. I've never noticed a problem with norton running auto protect before. Joel
if your cpu is being over-utilized by this, try stopping picasa media detection sideshow
Waste of resources Sumit
NAV AutoProtect. Never a problem on any of the machines I've serviced with NAV installed. Tooki
from Norton bloatware Service, takes 25% my athlon64 4000+ cpu-time Marcel
I know that this file belongs to the Norton Antivirus stuff, but the prob for me, is that it wont go. im trying to uninstall norton but my friend has deleted sum program files for it. so now on the quick launch, i cant end it, and its not working, so i was advised to end it manually by ending the processes, through a gruelling task of finding and deleting norton processes, i noticed this one wont remove itself from the process list. I cant uninstall it, and im left with no protection. David
60 to 80% of cpu resources taken by this file Leo
Hogs the CPU of a 2.5GHz desktop - replace Norton Antivirus with another program Marcus

Norton AV Auto Protect Feature - important for protecting my pc, but eats 30% of my new AMD64 CPU with 1GB RAM David
This one has caused a lot of problems for me. Whenever I download something big, run a movie or whatever sometimes it will scan it all through turning my new computer to a halt for 20min. Recently it has also caused some programs not to work properly. Will take several minutes before some programs will pop up after clicking on the icon. Also made surfing through IE very very slow. Uninstalled Norton and got rid of the file. I'm finally enjoying my fast computer. Michael
this is norton antivirus. it might slow your pc down but it's not dangerous at all sum guy
It's Photoshop! I just uninstalled it and got my PC back! Nice one John - thanks
use up 100% cpu adeel
slows cpu to crawl laptop wont shut down steve
It is anti-virus process, but east all CPU power and access HDD all the time guesit
It takes unbelievable amount of memory, I usually disable it. John
I closed my video editing software and it quit using up my cpu..studio 7 maybe some processes cause it to scan more than others??? Elsee
Thanks for the clue about photoshop elements. I use a CRe500 i APP USB card reader for my photo work. It appears that Photoshop Elements keeps checking to see if I inserted a card with any photos. Every time it does this navapsvc does its job an trys to check a file coming from a removeable device. This causes the system to trash. Unpluging the USB card reader fixes the problem until the next time you need to read a card. Charlie
John's advice worked for me. My cpu usage fell from a constant 50-ish to under 5% the second I killed the photoshopelementsdeviceconnect process. Britt
as mentioned, its a norton file. Norton is a cpu hog. I'd recommend trend micro, avast or kaspersky labs anyday before norton (with a preference for trend micro) Pete
Was never aqn issue until recently on my PC - now consumes 40-55% of CPU - I select 'end process' on task manager then re-enable auto-protect and the issue is solved - well for the time being! Paul
I go into task manager, end the process by right clicking in the file name. Shut down task manager the right click the norton icon in the taskbar and re-enable it. It no longer uses up resources. It just started acting up all of a sudden. MGTaylor
Causes several applications to run agonizingly slow! Rob S.
Process was CPU hog. At 60-75% of CPU. Stopped Picasa2 and CPU use instantly dropped to 1-2%. Thanks to sideshow for tip to stop Picasa media detector! MSC-SA
Takes up 30% of my cpu usage as well. Between this and winlogon.exe, i cant even run diablo 2 smoothly on my 2ghz, 1gb ram machine ( anyone know how to fix either? Greg
I uninstalled photoshop, still nothing. Its just sitting there eating up my CPU spencer
Uninstall some versions of Norton and they leave the shit behind. Dan
Part of the Norton package, processor power requirements are too high! Cleaner56
Indeed cpu consuming file from Norton. Guess this happens when your subscription is no longer valid. Try update with Live Update or close Norton Anti Virus...  See also: Link Nico
It seems to be part of Norton Suite, seems to be uncompatible with Photoshop products, unactive, uninstall Adobe Photoshop Downloader and the CPU time usage will drop. Mario R
The reported Photoshop problem also affects Picasa. Kill the Picasa system tray task and cpu usage returns to normal. nemo
Lets see here it's created by Symantec, eats up cpu and it started happening about the time my subscription ran out, Id bet if I renewed it'd probably back off the cpu. Kevin M. Farley
It tends to be a bit of a snoop, youll notice that it tends to be more active on site that willm lends towards the entertainment field. The curious thing about it is that it tends to quit down when you began monitoring it. Almost like a child, if you ignor it, it's will likely missbehave. Check up on it every now and then and it seems to behave a little more responsibility. Then again it could just be that part of the computers intelligence that simply imitates the behavior of the one sitting there in front of it. It's as if it was racing to keep up. There now, i have it purring like a kitten. Toby
Its absolutely safe. Norton anti virus is the best anti virus programme and it does not slow down my machine at all. Ashish Agrawal
It's a norton antivirus auto protect file. If you want full virus protection you leave it on. It makes my computer unusable for 2 minutes after bootup. Going to disable it and find another antivirus program. Joe
I can't shut it down in processes. It eats up to much ram. Its a real bother since I no longer have nortons. Kristi
It can use up CPU if another proxy or service is running Crash Gunder
its annoying as hell, just like nortons other 100000 processes bob
Should i end the process of navapsvc.exe? Ravi Rawji
If you have Norton its part of the package
Just updated to AdobeReader 8 and the update also installed Adobe PhotoAlbum and navapsvc went wild. Uninstalled Adobe PhotoAlbum and navapsc went to 0 so it looks as though there is a conflict. Potter John

Try unplugging any USB devices such as Card Readers, It worked immediately for me, from 40-50% CPU Usage to 0% Incant8rix
It is a malware eating up memory. It is named after a process of Norton but it's not Norton. I solved the problem with Outpost Firewall ... I blocked the process and that was it me
Was a huge CPU hog for me until I turned off SDmonitor which I believe is my multicard reader and CPU usage immediately went to 0% 2 minutes hate
Owned by Symantec. makes them evil. Symantec previously sent 750 malicious emails a day to twc-industries.com now known as Time Warner Cable... on top of that Symantec would say a specific code was a virus while infact it was LEGITIMATE for example in 95ish Diablo was one. is this the form of a wrongfully forced Boycot on the unknowing user?.... screw symantec and everything they make. its junk. thats why its slow. their coding (im guessing) is first (the old stuff) blocking things they shouldnt then the new coding is telling it to unblock it? im not certain. but there is no reason for lag.

Cardreader/printer attached causes high CPU. Disconnecting printer with integrated cardreader drops CPU usage by navapsvc. Fix found by searching "navapsvc.exe cpu" on Symantec support site.  See also: Link RonH
Symantec support page "navapsvc.exe cpu" did not work as I previously thought. It only shut off Auto Protect. What DID work was placing a memory card in the cardreader so that navapsvc.exe could scan it and then go to sleep. Now using 00% cpu again with printer & integrated card reader attached. Ron H

Process can be a memory hog. It is taking up over 200MB of RAM on my machine right now while doing absolutely nothing. NAV 2003. JMP
It stops some programs from running because it takes up so much of the CPU memory. I never had this problem before I tried Norton. I'm going back to the other program. Darlene
After your program downloads the automatc protections updates, your norton antivirus starts a quickscan...disable this feature under norton options for antivirus and you should see a difference. The wizard
99% CPU are taken off by it. System crawl like snail. Wesley
It eats up my CPU and make my computer run slow, start ups take a LONG time. Is is safe to stop the Navapsvc.exe process on the Task Manager? If it is safe to end it's process,, then I will do it. nicole
The process is an extreme user on my system at start up, which for me is no surprise as my computer has a processer less than a gig and the RAM is horrendous. However, if I just let it do its thing, I can easily have back the speed I usually have on my computer and the CPU usage is usually about 7% steady all together for me with this process running continuously. So unless NAVAPSVC.exe came out of nowhere and you don't know where it came from, there is actually nothing to worry about except maybe finding a better processor that works with the rest of the computer or just living with the usage Alexia
This file eats about 55% of my CPU at times it makes my CPU be used up to 100% with other programs opened. Defenedly extremely annyoing. Someone said that if you complaint about your cpu being completely taken because of this program that you must have an ancient computer. I got a 3.0GHZ PENTIUM 4 and let me tell you there is nothing slow about my computer. But this file keeps getting in the way of everything i do. Is there a way to make it so that it doesnt take so much CPU or to actually remove the damn thing? any info will be appreciated. Juan
it wont let me delet this product i want to clint
It eats up ram - huge chucks of ram and it cant deltet it -- do not install norton it is a virus - and I have duall core procesesr not slow James Beuthling
there goes 96% of cpu power. Slows computer down big time. A real turn down. Just uninstall norton. There are more options out there salt
