Having done the research from those who test Antivirus programs (av comparatives, virus.gr,others and other professional reviews) the highest rated free programs is

Avira Antivir http://www.download.com/Avira-AntiVir-Pe...

one of the top Antivirus Programs is Nod32, you can download a 30 day free trial.

However Today you are in just as much danger from Spyware / adware trojan etc.. I Recommend SuperAntiSpyware http://www.download.com/SUPERAntiSpyware...

( I used this to remove spyware from a laptop that adaware would only detect but not get rid of )

You can also Download and Run Advanced Windows Personal Care,

http://www.download.com/Advanced-Windows... Sometimes you can run this in safe mode, which would enable you to disable harmful programs before they start in normal mode.

(I recommend you uncheck the Registry tab, but pay close attention to the spyware, security and startup tabs and see what is starting up and disable harmful items. Run this program in safe mode if possible. http://www.computerhope.com/issues/chsaf...
