Ad-Aware and Spybot are both good things to have and use, but they are intended to look into spyware, rather than viruses or worms. Do you have an antivirus program, like Norton or McAfee? If not, I suggest you do so. Those two are commercial programs which will cost you, but fairly good A-V programs are to be had for free.

I have Norton Internet Security, which provides a firewall, and a spam control system, and virus diagnosis and cleanup, and more. I swear by it.
