My main objection to Norton is that it is "arrogant"...by that I mean that it seems to assume that there is nothing else running on the system?

It tends to have problems with other suppliers' products, such as firewalls, which could well be causing the problems that Ali refers to. Also, it seems a bit slow to load, so you might have to "tweak" your boot sequence to get it to load and complete and return the RAM before something else cuts in and contends with it. OK "memory leaks" aren't quite the issue they used to be because systems have a lot of RAM these days, but that is no excuse for sloppy programming IMHO

As a product I think that it is just fine, but I have had just a few too many problems with it (because of the above issues) to recommend it to my "granny" so to speak

Please do not get me wrong, I am not against Norton as a product, and know a lot of people for whom it works just fine. It is just that it is the main AV product that I have had issues with.

AVG is a sound product that I have never had any contention problems with, same goes for McAfee and PC-cillin.

Just my thoughts.......if NAV works for YOU just be sure to keep it up to date, and watch for firewall issues.

Cheers
