Free, AntiVirus for Windows, Free

Individual Windows users concerned with cost have multiple choices for free anti-virus software.

Reviews of some of these may be found here and there.

AOL Active Virus Shield (requires you accept spamvertising, which can later be turned off).


Avira PE

AVG anti-virus and anti-spyware



Antidote SuperLite (scanning only)
