Norton 360 using over 30Mb/s! Please help!

PLEASE HELP ME I AM THIS CLOSE TO SMASHING MY COMPUTER WITH RAGE! I am a gamer with a 64 bit windows 10 computer. Recently my computer has been going very, VERY, slowly. I checked my task manager, only to see Norton with 30Mb/s of my disk at use! My Norton 360 subscription expired recently, so is this some stupid technique to get me to pay another 50 bucks for another year? I don't have a job yet! This is the worst my computer has ever been! I have bbeen using your product for many years not! I would give you more specs on my computer, but my computer is so slow it takes 5 minutes to open up the start menu now!
