For whatever reason, svchost.exe attempts to gain access to www.exitguide.ru about every 15 minutes, which I know is a malicious site, and obviously a malicious program is at work. However, superantispyware does not detect anything wrong with the computer. I have the latest updates and am running a complete scan, but my firewall is still blocking attempts to access exitguide.ru by svchost.exe. What is the problem here and how do I get rid of it? Also, after I posted this message, svchost.exe is attempting to access www.gravatar.com as well.
