So the problem (for me) with not being able to get to the Avast notification window was due to the fact that I was running Nova Launcher. I went in, temporarily reverted back to Samsung’s TouchWiz, and then followed the procedure outlined previously and I was able to successfully get to the Avast notification page where I could clear the “privacy issue”. I re-enable Nova Launcher and so far everything seems to be working correctly without seeing the privacy issue again!

Thanks for all the help!
