For everybody out there. Those products are all shareware. Ad-aware and Spybot S&D are both freeware. For every product that is there, there is a freeware product that does the same thing. Don't waste your money. Try
http://www.snapfiles.com/freeware/freeware.html instead. There you'll find products that have been proven to work. Not that those don't but it's better to download products that have been recommended in this forum. Especially since most people that post here have no idea what products to use or how to use them.
