i used avast and avg before i got norton
trust me, they're useless
with them, my comp(old one) still got infected somehow
Just fyi, AV programs can't detect all types of malware. Some of
them can cloak themselves from AV programs through the way they're
embedded in the files, paid AV program or not. Among all the free
ones out there, Avast and AVG are among the highest rated ones
If you ever decide to uninstall norton, I'm sure that you'll see
a vast improvement in the performance of your PC. I'm speaking from
experience that I've had in troubleshooting quite a few PCs. Half
the time when someone tells me his or her computer is lagging
horribly, one of the first things I do is to check if they're using
Norton.
Edit: Supposedly Norton has fixed the performance problems to
some extent with Norton 08, but still it's being viewed as a major
resource hog that causes intermittent system hanging. Do check out
some reviews for anti-virus programs. For one, let me direct you to
some reviews posted by users on
PC World here, and on
CNet here .
