i'm sure you'll get a lot of posts for AVG. after all, it's free and it works....i use it.
in the past, when asked about commercial AVs, i used to recommend other products but then i was struck with the thought, "Hey, if i trust the free version of AVG, why wouldn't i trust their stronger, 'industrial strength' version? and i couldn't come up with a argument against so it...so i would say that i recommend AVG, either free or commercial.
i don't like the norton av...you couldn't pay me to use it.
