Honestly I've never heard of it. You really hit the nail on the head though; I think though that as long as you're not retarded on the internet it doesn't matter what AV you choose. I ran my home PC for years w/o anything, but now I just use MSSE. The worst of the viruses that I see now are the rogue AVs that spread via facebook, and then tend to go through any and all AVs. Probably 75% of what I fix at the shop these days are removing those, and most PCs had some up-to-date AV installed (including all the big names).
