Avast antivirus - Works great Virus free for 2 years now.
Advanced windows care - I liked it so much I decided to By it
Ad-Aware 2007- Great spyware program
Dustbuster XP - Cleans the cobwebs out.

Mainly what: A site advisor for firefox and internet explorer that alerts you of unsafe sites based on user reputations. If someone gets a virus from a site, they rate it unsafe. It also has a comment system so users can leave feedback on why a site was safe or not.
Firefox-a safe, and easy to use browser
Advanced Windows care beta 3-helps you control your pc
Realvnc-allows you to control your computer from anywhere
Pctools antivirus free edition/spyware doctor starter edition-Two programs by the same company, both of which are free and work very well. The starter edition of spyware doctor however, can only be downloaded through the google pack. They also have a firewall plus which I haven't tried yet, as my family uses bullguard which costs.

AVG

Limewire

ZoneAlarm (firewall)
Mp3 Tag Stripper (what it says)
Ad-Aware (anti-spyware)
Spybot - Search and Destroy (anti-spyware)
GOM Player (Great video player - including .flv files)
Opera (browser)

I missed a few
Slimbrowser
deep burner

GOM player
Winamp
MSN messenger
