Im a mcaffee man, runs great takes no resources, upgrades over internet, or network mapped drive, or ftp server (net or local server) Great support. Ez to install.

Cant stand Norton, nthing but problems. it will blue screen windows, make it run slow just to bulky... (free upgrades and dats)

my opinion:

Amd - Mcaffee
Intel - NAV

Asus/intel/msi - NAV
Gigabyte/soyo/tyan - mcaffee

Dont now but its like who sticks with intel seems like like the poor things in computer systems...hummm

Its like, getting a amd chip faster cheaper. Getting a asus board it sux never works frys out other hardware. Installing NAV screws up windows (not like windows is perfect)

Mcaffee has free upgrades, NAV doesnt.
