I have Norton Internet Security on my MacBook Pro through my XFINITY subscription. I use Application Blocking and generally do not have issues, but cannot eliminate Norton Notifications for the Snagit app. Both Snagit.app and Snagithelper are blocked by Norton even though I always select "always allow this application." Sometimes the Norton Notification Dialog makes me make my selection three times in a row and on the third iteration, the "Next" button is greyed out. I also tried shutting down Snagit immediately after making the "always allow..." selection in Norton, then restarting Snagit, and the Norton dialog box still appears. I use the latest versions of Safari and Chrome as well as Snagit 3.3.5 (78049). Help!
