    I use "avast". I found 4 viruses on my PC.....use to have "Norton's Systems.......took it out...too much "power-over-load" for my PC. Now a lot of people use "AVG". Some say it's "free".....but I only found "trial" versions of AVG. Avast rocks !!!

    Hi armiger,

    While what dr911 has already advised is a among the best free AVs, what do you mean by best?

    Some folks like an AV with realtime scanning or not, some like them with a small memory footprint and others don't care as long as it gets the job done. One attribute among the best AVs is a frequent, perhaps even daily if not multiple updates of definitions on any one day.

    A signature based AV scanner can only catch those viruses for which it already has a signature, not the late breaking network virus that spreads in the wild very fast for which no one AV yet has the signature. Another attribute than signature based is heuristic. There are some which employ one or both.

    AVK from Extendia is an example of both - it uses Kaspersky and BitDefender (although it is not free).
