Ree's musings

Cherished readers, I have a little favour to ask of you: recommend me a free (or budget-priced) antivirus program for Windows XP, please?

I'm familiar with Bitdefender and AVG Free.  I'm leery of using either again, Bitdefender because it forces me to re-register on a regular basis, AVG because I'm pretty sure its TOS only allows me to use it on one computer at a time and I'd rather not violate that.  (I know I could and I'd get away with it, but I hate to rulebreak when Grisoft is willing to let me use their software for free.  Otherwise I would run AVG on all my PCs — it's served me quite well.)

I've also heard vague positivity about F-Prot, ClamWin, and Avast! but I'd like to hear user experiences before I install something.
