My computer has been infected with "Windows System Defender" malware. Should I restart my computer?

If I were you I'd check with a few spyware removers before hand, and possibly try to find Windows System Defender's registry entries (list: a href="http://www.spyna.com/parasite/rogue-anti-spyware/windows-system-defender)" rel="nofollow"http://www.spyna.com/parasite/rogue-anti…/a beforehand, just to be on the safer side.
