I have used AVG Anti Virus, Zone Alarm Firewall, Spy-bot Search and Destroy and Ad Aware both spyware killers for years. They are all free for personal use and I have had no trouble with Viruses Trojans Hackers etc. I have just upgraded to AVG free 8.0 and all seems good so far. Zone Alarm allows a lot of personal configuration unlike the Windows Firewall. They can all be downloaded from http://www.download.com/ I also use Windows Defender from the Microsoft site. It is safe to use two anti-spy products but never use more than one A/V as it can cause conflicts. You should run A/V and anti spy weekly. Hope this helps

spybot or spyware doctor…
if updated regularly, both works fine.
Spyware doctor is one of the best, but not free.
Spybot is free.
You can easily download it from : http://www.download.com

I would choose Spybot from http://www.spybot.de
Those Germans did a great work and it is free. I’m using it since 2003.
It is very light for the computer and contains tenths of thousands of malware in its database.
