When I boot up in the morning, my Norton icon has a red X on it. When I click on the icon, it shows Sonar failed to load? After about four or five minutes, the red X goes to the normal green check and it looks like Sonar has loaded. That PC is a dual boot Windows 7 and Linux Mint 18.3 Cinnamon. Could this dual boot feature be causing Sonar to load slowly? The scans, LiveUpdates and performance features all seem to work correctly, Sonar is the only program giving me a problem and that might not even be a problem. When I click on Support, the scan shows no problem found. I an running Norton Security 22.8.1.14 and us updated at least daily. Is my Norton's developing a problem?
