I've compared all 3 myself in the past, and AVG is far and away the winner. AntiVir & avast are both much slower in their scanning, and avast launches an excessive number of relatively memory-hogging processes. AVG has the better track record as far as detection according to VB100.
No OS should go without antivirus software. A lot of people are going to get caught with their pants down when some virus writer decides they want to write a nasty one for Linux. Security through obscurity isn't really security.
