Normally SVhost.exe doesnt mean you normally have an infection. If your AV and your AS (Anti-virus/ Anti-Spyware) does not turn up results, it's possiable you don't have an infection. Having a certin number of svhost veries from computer to computer because of what is installed and what drivers are running.
Now, Windows Vista taking over 2/3th of your memory is abit of a problem. I would see excatly what it is taking that much memory. If it's the SVhosts.exe. I'll be honest, I'm not sure what the issue could be without me seeing alot of information about your system.
