Installed norton security on my laptop and I had a issue were the app would not run any scans and the security button was red. Live update was working. Windows 8.1 is showing antivirus and firewall not on and will not change. Removed fast start up, ran power eraser, restarted computer many times. Still Red. Went to Norton security website Had them remotely access my laptop. He did somethings in the registry. He restarted my laptop now it is stuck on 10% scanning and repairing drive for 4 hours. He called me and said this will take a hour! I am still waiting. Has anyone else had this problem with Windows8.1. I installed this Norton Security on my desktop windows7 and had no problems I have a license for 5 devices.
