Or additionally, Spysweeper, which gives you one free download of the anti-virus image. Then you either need to upgrade or purchase a subscription.
I've been using a 4-prong attack to fight Spyware...I keep finding people whose computers are completely hacked, and they're nearly impossible to restore after they reach a certain point.
Step 1: Firefox instead of IE. There's just not the same penetration, although there certainly COULD be. I think a lot of hackers just have it out for Microsoft.
Step 2: Windows Antispyware (actually GIANT).
Step 3: Ad-aware (

Step 4: Spysweeper
I found that Spysweeper ALWAYS picked up more than Spybot (also free) and Ad-aware, but that ad-aware usually picks up some other "non-critical items". I'm not sure what Microsoft's Antispyware has ever accomplished, but it's there on my system doing its thing.
I should also add that ZoneAlarm as a firewall (free) is also a good decision.
