Mcafee sucks too,, trust me we have it at work, corporately, and other than lockups, memory glitches, sound issues, and update delays with the scheduler, it looks good,,
Norton i prefer if given the choice of the two,, but then again, could be that you have an MBR scan at boot, and if you have a hell of a lotta software,,, that will take a looong time,,
plus,, maybe your machine is poorly installed, low ram,, lacking HDD space, bad processor, or maybe ,,,, A GATEWAY!!!
eeekk!
