For a year or so I'd get a "No coverage" pop up from Norton. I'd call Norton and they would say that I had a years coverage left as I had an automatic renewal set up. Finally turned it over to sharpie in India that I couldn't understand a word he said but the exchange took place by typing questions and answers. Took him around an hour but he ferreted out the problem no one else could find. When I got my present lap top around 3 years ago it had Windows 8.3 with Norton installed and has been updated through the years to Windows 10. The Norton program for 8.3 IS NOT compatible with Windows 10. I guess the hackers have had open season since I've been on 10.
