My computer (Win-XP SP3) slows to a virtual crawl within a few minutes of booting it up. I noticed in Task Manager that one instance of svchost.exe is pegging 99 and 100 percent CPU utilization and that the memory associated with that process is HUGE (I've seen it over 450 meg!). I Googled the problem and found that Microsoft has (or had) a fix for the problem that was associated with Autoupdate ... but that was back in SP2 days and I am at SP3. If I use Task Manager to stop the resource hog instance of svchost.exe, I can't start other programs (double clicking a program's shortcut icon on my desktop results in an hour-glass as if the program is starting, but then the hour-glass goes away and nothing starts). At that point I cannot even start shut down and I have to resort to a manual Power-off.

The system is so slow that I am unable to run the computer's virus scan (AVG free) to completion) even leaving it running for 9 hours over night! Malwarebyes and SuperAntiSpyware both grind to a virtual stop within a few minutes after starting if I start them immediately after booting up the computer, and never even get off the ground if I wait until svchost gets cranked up to start them. Likewise, I can get on the Internet if I hurry up about it right after I boot up the system, but after the system runs for awhile, IE gets so slow I can't accomplish anything. I am posting to this forum from a different computer.

What steps can I take to resolve the svchost.exe resource hogging problem?

I've asked a mod to move this to the appropriate forum. Please wait for a malware specialist to respond.
