Query: I've always had Norton but am planning to defect to something else

I read all the bad reviews of this product, but decided I've always gone with Nortons and they are the big name in anti-virus, so I got this. My machine is slow and clunky and I've been reading reviews -- and taking them more serious. This year, I'm planning to defect and give up on Norton's once and for all. Maybe my machine performance will get better -- friends who've removed it say their machine's performance has improved dramatically. I'm sorry I didn't pay attention to the reviews last year.
