svchost / 100% CPU usage problems on start-up

Hello, Community.

 

There have been several threads about this. I posted on one that it seemed that my updated NIS was causing the problem. Norton's Help Team advised me to re-install; I did but I still have the problem.

 

There was advice in one of the various threads (one that I can't find!) that suggested using Windows Task Manager as a starting point.

It suggested adding Memory Usage & PID to the Processes display. It also showed how to slow down the refresh rate so that you could make a note of the 'offending' svchost.

 

I did. It has spotlighted two processes as being the main culprits, PID 1876 & PID 1964.

 

That's excellent news - or it would be if I knew how to trace the process using the PID!

 

I've found this article:  http://support.microsoft.com/kb/824344

 

I don't recall it being mentioned as a solution in any of the thread that I saw so I'm reluctant to use it.

 

Is it safe for me to do what this says, including using the WinDbg debugger? Does 'debugger' mean there's a problem in the code rather than a virus? Has anyone tried it?

...can shouw you in real time which processes and sub-processes are doing what and when, including PID-info.

thanks Bombastus. I've installed it so will run it as soon as I restart. It's currently showing different results from Task Manager!
