At your suggestion, I am trying a 30 day free trial of this AV. I have used Norton for a couple of years, but with the upgrading of Windows 7 to 10, and their total change of systems during the same time, it has caused problems for lots of their members, like myself who were not updating to W10, my computer hardly worked, and I was not getting windows updates or able to install ones I got. What happened was they had changed my new update to W10, so it was not compatible to my system and thousands of others. I had to clean all of Norton out of my computer, then installed the ESET AV8, which I love, computer is quicker, it updates automatically, my computer is a lot quicker. Think it is a keeper after trial run. Hope that Norton can get it's problem fixed, you can't get support, unless you want to wait 90 minutes on your computer, then the tech can't fix problem. I still get updates from their forum, and people are still experiencing problems, who had this issue.
