Hmmmnn.... Interesting site there, Dallas. I'll have to check it out.
Right now, I run ad-aware every once in a while. I have yet to find any spy-ware, unless there's some spyware out there that it doesn't catch.
Look in the "Security and Privacy" section under the "Cache and Cookie" listing for anti-spyware.....but I think Lavasoft's Adware pretty much handles it.
