Ad-Aware is a shareware program that identifies and removes spyware. I suspect that Spybot does much the same thing.
I use Ad-Aware, and it repeatedly finds a spyware item on my hard disk called valueclick.com. This is apparently loaded as a result of my visits to PPRuNe. This is why I made the original complaint.
Danny, is it really necessary to dump this unwanted stuff on us?
