I like SUPERantiSpyWare for the spyware. I use SpyBot and ran into a terrible problem called Zlob.Downloader.bs. It would not get rid of it. So did some searching and found all kinds of links with the problem. I used the SUPERantiSpyWare and it got rid of it.

I also like Avast for antivirus program. I was using AVG but the 8th edition really really bogged down everything!

I like ZoneAlarm as well.
