Avast! Free is a good program to use. It catches a lot things in real time unlike other free programs. It also has the option to run a boot time scan which catches a lot more problems than a normal scan. It works really well, I would recommend it. Just search google or yahoo for Avast! Free Anti-virus. Good luck.
