Windows 8.1: Information Message showing up from Charms area

Whenever I go to shut down my computer at night, a message from Norton pops up on the right side of the screen. I believe its some kind of information message. I am using Windows 8.1. It comes up as a notification from the right side of the screen from where the Charms bar can be found. I will try and get a screenshot to post soon. Can someone provide me a solution to fix this?
