This free software is really good
go to the website http://www.spywareterminator.com/app/features.aspx for features.
I think it's better than ad aware and spysweeper. it also scans viruses and it scans really fast!
It sounds pretty good, I'll try it later.
This program is very good and would recommend it to anyone who is on a budget, or just wants a quick fix for free. I have a funny feeling they may start charging for it when enough people like it.
