nortan might have more Features, but i think it's a bit slow on scanning and stuff. i have had nortan 2002 for a year and when i needed to get a renewal i just un-installed it as it was not worth the cash. now i use avg and it's workin good, plus it's free. theres some other ones out there too such as anti-vir XP and Bit defender free edition. Theres also one called kaspersky which is prettey good, but not free.
