I have a problem with my girlfriends PC. The CPU usage is never less than 80%, even when no programs are in use, internet not connected.
I checked task manager and there are 10-15 processes that seem to be using this 80%. It does seem to vary which ones, but generally the svchost files and the Mcshield file.
As routine I have made sure that she has ZoneZalarm, McAfee virus scanner, Ad-aware and spybot and try to get her to run them regularly. It was when the virus scan took 10 hours that i realised something was up. I have followed all the steps you recommend, with the programs you recommended, running in safe mode when appropriate. In safe mode, the CPU usage is fine, 98-100% idle except when running a program.
Her son, even though i have told him many times, will happily download and run any old program, so i suspect he my be the cause.
Here is the hijackthis log from today and a snapshot from procxp that i did today as well if it helps.
Thank you for any advice you can give
Dave
