If you keep up on windows update, you should have the latest (June's) version of Microsoft's Malicious Software Removal Tool
You can start it up via:
XP: Start->Run (or Windows Key + R) mrt
Vista/7: type mrt into the text box
Also, Microsoft makes a free AV solution called Microsoft Security Essentials. As far as free ones go, I like it the best.
