t-omen Just kill this process. Does not do any harm. Only uses about 101% of CPU when in progress... Whenever my CPU utilisation runs high I just look for the ciscv.exe end end it - CPU usage drops to mere 1-10% immidiately as of result.
Duke Microsoft Indexing Service - Not needed on most computers today.
jslfns Windows Indexing service somtimes takes a lot of CPU usage slowing down performance
Your_Name_Here If it isn't dangerous, it uses resources just like 80% of XP's useless processes.

Tman M$ index service to speed up searxh program, while slowing down the whole computer. Hmm
Could be a trojan, keylogger, or Windows Indexing Service.
minylites MSWinXP but cause CPU runs @ 100% speed as shown in Task Manager.
Lukas it can be a Perfect Keylogger executable file, but it's a Windows file too
Oliver It keeps me from use search functions at the computer, takes a lot of CPU... When I shut it down (using ctrl+alt+del). The computer becomes normal! DELETE IT !
Content Indexing Service part of the Windows OS
Scrapper Indexes your entire HD, if you have lots of files it will use lots of RAM and CPU. Detects idle time by the amount of CPU and drive activity created by user. If you are reading mail, writing docs or similar low resource applications, system thinks PC is idle, hence will assign vast quantities of CPU cycles and RAM to index as quickly as possible. If it bothers you, turn off Indexing Servies, under the Find feature, as mentioned. Can be annoying if you start trying to use your PC while the indexing is running as takes a little time to give back system resources.
Leland This is usually part of Microsoft's operating system, it monitors the indexing service to make sure it doesn't use too much memory; however it can be a resource hog. You can uninstall the service from control panel add and remove programs. If you see two instances of this in task manager you probably have a keylogger.

Chris Completely useless indexing file =) But I didn't understand where in the F3 search dialog to disable it, please tell me!
Wes microsoft, indexing service, can be enabled and disabled in "F3" search dialog
Bryan I always immediately shut down this program whenever I start my computer up. If you leave it running, every now and then it will max out your CPU and your computer will stop responding, which needless to say is incredibly annoying.

Tear-a-bite cisvc.exe is a process that belongs to the Microsoft Windows Operating System. It is used to monitor the memory usage in CIDAEMON.exe and prevent low memory problems. This is an essential system process and should not be removed. This program is an essential system process and should not be removed.
fiju I have it cionstantly running Also its location is C:\WINDOWS\system32 and in C:\WINDOWS\dllcache. and when i try to turn it off in Find preferences it WAS ALLREADY OFF ...
Indexing service. I used to not let this run, but lateley I've got it going, as it does speed up my PC searches drasticly. I'ts set as a ow priority so it takes a back seat when running PC. As mentioned above, it may take a little time to give beack the recourses, but for me right now it's worth it. Note: I've tried Google desktop search etc. in the past, and it requires the same type of index as well.
Grasshopper It never showed up on any scan until today. System slowed dramatically so I scanned with Spyware Detector which has been run many times on this machine and never alerted on the file. Today it did and found 32 related entries in the registry. Quarantined and deleted the file.
Chris Trojan by blackcore/KillHouse Inc, If its sitting in yer temp directory, which it should not be (Its a sytem32 file) then BLAM...trojan. Antivirus will pick it up as such.
Patrick It's a Windows component. But if you want to use video cutting software for generating new mpg or avi files there could be problems with the sync... means video and audio stream doesn't really fit anymore. Why? Indexing process works in a sporadic way! Poison for the synchronisation which needs constant access to the CPU!
Mattiaus It eats up my CPU processing power whenever I try to actually load anything. Disabling it Helped me, but i'm afraid to remove
windoze if cpu is running 100% I kill off cisvc and it drops to 2%
John Cisvc is used to index your computers hard drive when your computer is idle, so next time you search, it will be "faster". It can be potentially dangerous however, if you are using an application that uses lots of power, and CiSvc decides to start indexing, it can heat your cpu to over 70*C. MBs without automatic fan control can potentially burn out. My core 2 duo reached 85*C, and the computer suddenly turned off to avoid damage to the cpu. Cisvc somtimes does not accuratly detect when the system is idle, and as a result, exessive CPU load can occure. Turn off!
Tim cisvc.exe is the biggest pain i have coem across for taking up CPU usages in my past 10 years of computer usage
snak123 If you find yourself killing this process regularly, go to control panel, administrative tools, computer managment; look under service and application; go to indexing service and look at the start up type column. If it is automatic, change it to manual and it won't bother you again.
Aris Not spam. It's part of Indexing service  See also: Link
