Norton 360 keeps spamming me to install the Chrome toolbar

Everyday I get a popup in windows from my Norton 360 taskbar icon stating that my Norton Chrome Extension is not installed and despite the fact that I click "Do Not Show Again", the popup keeps reappearing. I'm not paying $80/year to be spammed by a program that is supposed to be protecting me. I don't need this toolbar and don't want it and don't want to have to keep seeing this pop-up every time I open Chrome. How do it turn it off?
