My past experience with Norton is horrible. I consider it a virus and was very frustrated with the trouble it caused me interfering and slowing down my computer. I wouldn't use it if they paid me.
Norton is a PITA. I just bought a brand new HP Pavilion 490t with a six core processor and 10GB RAM and Norton had it running like my old Win XP Gateway. I removed Norton and installed McAfee enterprise and now it’s fine.
