svchost.exe hogging CPU

Factual Questions
1

I have Vista Premium from a few years ago. I have a number of svchost.exe processes running right now. Most are using no CPU, but one is, and a lot of it, 48% at last check. I kill it, and it comes back. How do I stop this?

I am running only Google chrome, btw.
