Hello. I lost my current Norton 360 program during a complete PC refresh. Somehow, I ended up with a trial version of Norton Internet Security, while I was reinstalling programs. I've received notification that this will soon expire. I still have my authorization code for my current 360 subscription and instructions for how to download the program. My question is whether I need to uninstall the existing trial version of Internet Security before I attempt to download 360 again and reactivate my subscription?
