Put me into the " I love AVG " camp.
I just dumped Norton and Macafee off of 7 different computers. I tried the AVG virus/firewall program on my 2 home computers and liked it so much that I bought a 2 user license. I'm very, very happy with the results. AVG does what it advertises it will do! ...without being bloated and resource intensive.
I just installed AVG on 5 computers at my church this morning, dumping Macafee. Their subscription process used to be so easy, but now they want you to buy a whole upgrade (for $39.99)
Figuring that I've bought 7 licenses of AVG for $229.00 total, that works out to about $32 per machine. But AVG license is good for 2 years, which brings it down to $16/machine. I think that is a really good deal

And, they don't make you jump through hoops with the rebate crap.
My thanks to the poster who turned me on to AVG.
