A great site call www.lavasoft.com. They have a free download call As-Ware SE Personal that is awesome and does more than a moment ago adware. A must for a clean computer beside a frugal budget.
try AVG.com it's free and it is working good on my putor....moral luck
www.hijackthis.com
http://free.grisoft.com/doc/1- go in that and install the Anti-virus and anti-spyware .
For trojans: Mischel Trojanhunter http://misec.net

For adware: Spybot Search & Destroy, Lavasoft Ad-Aware, and Ewido/AVG.
There is mcaffe, Norton 90 free daylight trial except that i don't now for spyvere i suggest counterspy free trial within is adwere spybot but they are less affective
