My friends Dell laptop with Vista home premium installed has a problem with one of the SVChost.exe process taking 50% of the computers resources. This only seems to happen when the computer is connected to the internet. The problem makes the computer so slow that's it's nearly impossible to work on it. I've tried to find out what the service is connected to, but can't. Can I end task on this service without damaging the system? Also, any idea what is causing this and how to correct it? Thanks.
