Because of the rave reviews, and poverty, I grabbed AVG when my new machine got hit by slammer. It was a dissapointment on multiple fronts. (Yes, I know some of them are because it's free.)
When I browsed the folder with the virus, a popup whined about the problem telling me to open AVG. No record of popup, no fixing the problem. When I did enter AVG it cought only 1 of the three infected files. What's worse since I backed up my old machine, (with the 80g orignal drive attached) It insisted scanning everything. (The final straw came when I had to do the 3hr scan multiple times.)
Yes, I know it's free, but I don't think I'd pay for 1/3 virus protection.
For $12, I got free ship for Norton Internet Securty 2002, complete with a decent firewall and a year of updates.
