svchost.exe
Here is an interesting one.
A naughty little process is jamming up my system. If I connect to the internet this svchost.exe ramps up my CPU usage to 100% and effectively gums up the pc. If I remain isolated from the net all runs normally. I have checked for outgoing traffic, but things seem fairly normal, so I don't think there is any hacking going on.
Ending the process disables a bunch of other things like volume control, media players and screws up the desktop display etc etc.
I have tried the usual things, running virus scanners (AVG & Norton) and scanned the registry with Registry Mechanic, Tune Up Utilities and RegCure. Each one has found different problems but none has solved this one.
Would anyone have any ideas what might be going on and how to fix this rather annoying little problem?
