Norton is bugging me

Hi, Now my Norton Antivirus is expired, so norton keeps on poping up saying its expired. Norton never pops up when I am in flight but when a fspassengers window(such as company manager) opens, then Norton seems to like minimize my sim and pops up, normally I just get rid of that window by pressing tell me in 1 day, and come back to the sim by opening it again from the minimized window. But sometimes, the sim won't let me open the window(kinda froze) and I have to shutdown the computer. I don't want to fly 12hrs and while viewing my End of Flight Report, Norton pops up and freezes the sim. Do you think I should uninstall, cuz now its now no use since its expired.
