i've had this for a long time
I would also suggest COMODO Firewall , Hijack This (be sure you know how to use Hijack) Spybot Search & Destroy, and also Malwarebytes' Anti-Malware.
A great anti-virus is AVG.
If you can run all of these, i suggest it. My computer hardly gets infected. And when it does, a run of each of these programs will clear it up 98% of the time..
