The most popular free anti-virus is AVG but...

AVG is crap!

Mostly noobs, the naive, the computer illiterate, and children use AVG Free. These types love AVG because they say it is easy to use and almost never bothers them with any pop-ups or warnings. Of course AVG Free never bothers them, it hardly ever finds any virus to warn them about!

etc. etc. etc, ad nauseam, AVG fares poorly.

AVG has proven itself to be a miserable performer at best. Missing almost 20%, while trying to detect known malware, in some tests. Not to mention almost non-existent heuristic detection and infrequent "once-a day" updates.

AVG. = Average, at best!

There are much better free alternatives such as Avria Anti-Vir:

and Active Virus Shield:

The best one to get its McAfee VirusScan!!!
