Dependable Free Anti-Virus Programs

[rickyjo]

Just remember, although Norton, Mcafee and some others are huge resource hogs all the freebies that are well known (avira, avg, avast) all use about half, avira being the lightest. It's critical that you have a 2nd program as well (only let one run by itself!), superantispyware is the best.

As for a previous comment about the well known anti-virus software being unable to deal with new viruses, this is true, but not usually for more than several hours. It is unlikely that there will not be a very quick update for the virus you are infected with. Also heuristics catch the ones that are not discovered yet more often than not, especially if you have more than one program checking.
