Trying different route for computer protection...help required

Hi all -
I'm bringing up (2) semi-older laptops for home use and wanted to try a different route for full computer protection. My main laptop has a ton of protection (ie ESS, Spyware Blaster, Spybot, Anti key Logger, Firefox with extension, Prevx)

For these two other laptops I wanted to try the "free" route and protecting them. Initially I was going to try Avast Internet Security but decided to see if I can come close with efficiently pairing "free" programs.

The laptops will be used for Internet Surfing (social sites, flash games, all over internet surfing, light banking (main laptop used for that), purchasing online)

Here is what I have loaded so far:

Laptop 1 (XP - all updates made)
- Firefox (with a slew of the top identified security add-ons)
- Avast free AV
- Online Armor free
- Spyware Blaster
- SpyBot
- CCleaner
- XP Firewall

Laptop 2 (Vista - all udpates made)
- Firefox (with a slew of the top identified security add-ons)
- Avast free AV
- Online Armor free
- Spyware Blaster
- Spybot
- CCleaner
- Vista Firewall
- Windows Defender

What else should I add? Is there an area I'm missing with the free programs?

Thanks much for your help!

 

I would actually suggest removing Spybot (& Defender from Vista), and adding MBAM to the setups.

 

I'm not familiar with MBAM but will take a look into it now. Thanks

 

Don't forget policy restriction and virtualisation. GeSWall, Returnil, and Sandboxie all have free versions. Also, if you want a behaviour blocker, you could consider ThreatFire.
