There are several excellent, and free, anti-spyware applications that you can use to clean your hard drive. Having at least two will allow one to find the ones the other misses (each looks for a slightly different set, depending on how spyware is defined).
I can recommend:
Spybot Search and Destroy
Links to these (and other) useful applications can be found here:http://www.bleepingcomputer.com/forums/topic3616.html
