OK so a bit of background; I got Windows 8, and my NIS subscription is about to expire in a couple days. It costs a lot more to renew than upgrade to Norton Security so I'd like to upgrade instead. I heard that it's counted as a new product and I have to uninstall NIS. Does Norton handle this, or do I have to manually uninstall and run a removal tool before installing Norton Security? Also, if I choose to upgrade by buying a fresh subscription, would that work the same way as an upgrade?
