Whats the best program to prevent spyware?

Ad-ware and spybot and good for getting rid of but I find they dont actually prevent it from coming in the first place.

microsoft has an anti spyware program. you might want to give it a try. :)

Also try Spyware Blaster which is a preventative, and free.
