Once you have Process Explorer installed and running:
Click/Expand the Svchost.exe process that you are interest in.
Then highlight one of the process listed under Svchost, right click and from
the options listed select: google
This should display what out there on the web about that process.
Are you sure about the spelling? The legitimate windows file is
svchost.exe not svshost.exe. If yours was a spelling error, know that
it is normal to have several svchost.exe instances running.
