As the resident geek, I am often asked about which antivirus I use on my WinXP PC (for those times I need to update my Zune…sigh).

The products I use are not very well known among those who know about antivirus, but they have 3 features to love - they are good, they are lightweight, and they’re free!

I usually rely on the results from Av Comparatives to decide on my antivirus. Currently, I use Avira Antivirus (and love it) - but going by the recent news of Avira not doing well on the Virus Bulletin 100 test, perhaps its time to change to … maybe Avast! .

P.S. I use Comodo as an excellent firewall.
