I can feel for you completely. I'm a computer tech and all I do is go to job after job cleaning malware off people's computers. I, personally, made the switch to Mac about eight months ago and have never looked back. A few minor compatibility issues, nothing major, but no chance of any kind of infection. Best decision I ever made. That being said, good luck cleaning your computer up, I know how painstaking it is. In addition to Spyware S&D mentioned above, try Adaware SE. For those really imbeded programs, you might need to use Hijack This! and/or do some manual registry editing.
