We have had very good success here with the Microsoft AntiSpyware beta product. This is a product of a company (Giant) that was bought by MS recently. The Monolith hasn't managed to screw it up yet. The combo of Symantec Antivirus Corporate and MS AntiSpyware has kept us spyware free for quite awhile. It did a good job cleaning up systems when we first deployed the product as well. People around here have learned to be careful with their browsing habits because we will blow away and reimage machines with
persistent/unsolvable spyware problems. That is a risk you take in allowing complete, unmonitored, unrestricted internet access.
