Anti Virus Replacements

I've been using a "free" copy of ZoneAlarm for the last year or so. However, as the trial period was over I decided to use some other software instead. I don't have a credit card and renewing ZoneAlarm was expensive and hard to do. I tried renewing it by joining SnapFish but even there, I can't get "free" photo prints without a credit card (so no Zone Alarm renewal).

At the moment I have bot Avast! and Comodo installed. There's a bit of overlap and potential for them to fight each other - Comodo, which I installed second, found all the quarantined stuff that Avast! had already moved, and wanted to move them again! I got Comodo because it has a proper firewall, but maybe I don't need to run the anti-virus component while I have Avast! running.

Any ideas on this? Which Free anti-virus and Firewall would/do you run under Windows XP, and why?

Earth Day

Apparently it's Earth Day "today" in the USA! I say "today" because technically it's the 22nd, and we (as in Australia) are already in the 23rd of April.

Writer's Block: Going Greener

[Error: unknown template qotd]I've already replace most of the lights in my house (despite the long life bulbs contributing to migraines), ride a pushbike or take the bus. I'm open to suggestions for more that I could do.
