I have been a Norton User for many years. I renewed my subscription in Feb 17. I then discovered that the restore system in Windows 10 no longer worked on either my PC or laptop. Many hours with Dell we unable to resolve the errors in the registry. My son discovered that Norton Tamper Protection prevents the restore system from working. Even worse if you have tried to restore with this protection on, turning it off will not solve the problem. Just reloading windows does not repair the damaged registry, you have to reinstall windows to a clean drive, in other words loss of everything on the drive. Norton are aware of this problem and if you dig you may find reference to this on Norton's site. Why was this not brought to my attention on renewal? Where is Norton's fix? None. Even VW have fixed my Audis.
