I have just had the same problem on my spare laptop. svchost,exe is hogging all the processor time. Even ignores Crtl/Alt/Del. Had a potter on Google and found some info there. I have tried running FixWelsh,exe from Symantec but with no success.
Seems to have lots of copies of svc.host running, some where you would expect (C

windows\system32) and others in strange places.
Any suggestions welcome.
