From: -Nisko- on 28 Aug 2006 19:27 For the past week or so, one instance of svchost has been hogging 70% to 90% of my CPU. I have tried many ways to find the culprit to no avail. Once in a while, when I boot, it doesn't happen - but, most of the time, it does happen. The result is that my PC becomes extremely sluggish - so slow that it's unusable. I use McAfee anti-virus and a variety of spyware finders - and the Microsoft Windows Malicious Software Removal Tool. None of these has found anything unusual going on. All my signatures are up to date. Can anyone help me rid my PC of this issue? Thanks.......

Svchost.exe is the host process, whether that by malware or a legit process. You can use PE to see what processes SVChost.exe is hosting. http://www.vernalex.com/guides/malware/tools.shtml If svchost.exe is not running out of the Winnt/system32 directory, then it's a Trojan. Go to the area about Process Explorer and learn how to use it to look at running processes. It may not even be malware that's causing the problem too and you can see all processes running with a host process such as an (exe). Duane :)

Thanks....... | Use the SysInternals ProcessExplorer and determine if SVCHOST.EXE is executed in a location OTHER than %windir%\system32 http://www.sysinternals.com/Utilities/ProcessExplorer.html If you find SVCHOST.EXE running in a different location, then its malware. Look at "thecreator's" answers for possible resource hoggers. -- Dave http://www.claymania.com/removal-trojan-adware.html http://www.ik-cs.com/got-a-virus.htm |
