Processor at 100%

[SGTRawlins]

Hi Ladies and Gents,

The processor on one of my desktops is stated as running at 100% by task manager, this is causing really slow performance, any ideas?

Cheers, Robo

One possible problem that this could be that I've had in the past is due to .avi files that cause explorer to endlessly spin it's wheels. Open the "Task Manager" and sort the processes by CPU usage. Check out what's eating up all those cycles. If it's explorer and you have large .avi files it very well may be this problem. The error is caused when explorer tries to scan corrupted .avis. By default explorer scans video files to gleen property information whenever you are browsing a directory .avis are in. You don't have to even open the file for explorer to die. There is a registry fix for this, but I don't remember what it is. It's posted in tek-tips acutally. somewhere... Let me know if you think this is the problem and I'll find it for you.

.avi registry fix:

Delete the registry key: HKEY_LOCAL_MACHINESOFTWAREClassesCLSID{87D62D94-71B3-4b9a-9489-5FE6850DC73E}InProcServer32

This prevents explorer from loading shmedia.dll which is used to in often useless attempts to read the properties metadata for avi files.

But my read is that it is either a worm, or general malware junk that is at issue for the problem. faq608-4650 should resolve the issue. There is a ton of stuff from Sasser to replacements of key XP system files with lookalikes that should be thoroughly inspected, identified and removed.

Before deletiong or changing anything, can you state which process is running at 100%?

 

[bcastner]

I hope it was clear enough, that I did not buy that it was an avi issue in this particular case, although it is a real issue.

I only included the avi "fix" in response to rayen99's suggestion.

I think it is malware.

It could be legitimate software pegging the proc, too. The McAfee framework service has a bad reputation for doing that when trying to run an update that it is having trouble completing. EPO 3 sp2a fixes this very issue.

 

[rayen99]

Yeah I've had McAfee do the same thing to me too. BCastner you're probably right in that it is malware. But, Rawlings let us know what is chewing on that processor.

Thanks or all you help chums, i will give it go and see wheather i come out trumps.
