Ad-Aware 6 was the first anti-spy program I ever used. When they stopped support for Ad-Aware SE is when I decided to dump it. I kept Spybot for years; it never found anything as I am a pretty safe surfer, but my step-father got infected with some adware pop-up, and while Spybot detected it and said it was removed after the cleaning process it was still very present, with the pop-ups still coming. Obviously it's no good having anti-spyware apps that can detect but cannot remove. Well, unless you receive some sort of enjoyment from manually removing spyware!
