A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web.
That being said, Service Host(svchost.exe) is a generic service hosting container. Any number of required system services can be running in them, so I would not get rid of them. You can use Process Explorer to determine what services are running in the host container. My guess is it's Windows Update or BITS running.
