Suggested Tools: Protect your computer

So I always get calls from people asking me to recommend a good anti-virus and spyware protection software they could buy. And the idea is, why buy it when you can get it for free? So here are a few tools I'd recommend:

Grisoft AVG (Free anti-virus, highly recommend it)
http://www.grisoft.com

Avast!antivirus (Free version also pretty good)
http://www.avast.com

Microsoft Windows AntiSpyware (Beta, excellent!)
http://www.microsoft.com/spyware

Ad-aware (Anti-spyware, look at the bottom of the page for current build for the free version which they keep almost hidden within the site)
http://www.lavasoftusa.com/

Zone Alarm Firewall
http://www.zonelabs.com/

Enjoy :)
