SVCHOST.exe causing 100% CPU load.

Kai · Guest

As stated in the subject, svchost.exe is causing a full load on my processor. Task Manager shows 5 occurences running, 1 classified as local service, 1 as a network service, and 3 as system. all but one of the system occurances remain at or near 0% but said one uses however much of the cpu is not in use and causes slow performance in all applications. another apparent effect is an inability for IE to open new browser widows when redirect links are clicked. IE will go in to "Not Responding" mode for about a minute, then refresh the original page.
I am using AVG antivirus and it fails to detect a problem, but due to the effects a virus/trojan seems the likely cause.

Hi Kai,

Sorry for the late reply.

Yes, you have a variant of the Coolwebsearch hijacker. So please first get and run the free special tool made to remove it. It is called CWShredder made by the author of HiJackThis. Just download it, unzip it and click on it. Hit the *next* button to run it and let if fix anything it finds

http://www.merijn.org/files/cwshredder.zip

Reboot your PC and scan again with HiJackThis. Post a new log here so we can see if there is anything else that needs fixing Smile
