How Do I Fix this High CPU Usage Svchost Virus or Whatever It Is?

//

After I log in, my system slows to a crawl. Looking at task manager I see that my computer is experiencing high CPU usage. Looking more closely I see that something called “svchost” is taking 100% of my CPU time. If I kill the process suddenly other things stop working. Is svchost a virus? How do I fix this svchost problem?

That’s actually a composite question based on several reports I’ve been getting recently.

Svchost is not a virus. In fact it’s a required system component. You’ll often find  several copies of svchost running.

Svchost, or more correctly “Service Host”, is a program that is designed to run other programs and “hosts” many of the system services in Windows XP. Several copies of Svchost run more than one service, which is why when you kill an instance of svchost several things on your machine might stop working.

So why is one of the Svchosts taking all your CPU?

And what can you do about it?
