When we add freeware AV choices to the mix, we can no longer say you pays your money and makes your choices. But at any rate, you still take your chances, and choose wrong and its your computer that gets compromised and not mine. Which is all well and fine for me until I realize I too am taking my own risks.
But the somewhat predictable AV choices are now in somewhat of a state of flux. Not only has, AVG, IMHO, self destructed as a choice, a brand new freeware choice called rising is entering the competition. Although not up to Avast in my opinion, its still impressive to go from nowhere to competitive in the first year. So it bears watching at a minimum. The other new joker in the deck may be comodo, who plans a stand alone active antivirus called Cavs3 which may be released this month. Comodo already has something called Cavs2, but even comodo does not tout it as even competitive. But comodo seems to think cavs 3 is going to revolutionary with a totally new AV model, and given their programming team, it certainly bears watching.
