Fixing SVCHost problem...

Hi all...

Recenty I faced with Copy.exe error in my office pc and some how I updated my virus pattern and detected and even removed it through deleting autorun file but the problem of SVCHOST still existing every time when I logoff and login I am sick seeing this error

"windows cannot find C"\WINDOWS\SVCHOST"

and when I close it again

"Desktop cannot load C:\windows\SVCHOST"

how to rectify my svchost file is located in c:\windows\System32

how to get rid of this...

Thanks
Hari
