So last week, after getting frustrated because of having to reboot the computer to get Norton Security to load, I uninstalled. Twice, because the first reinstallation got corrupted. But the problem has returned. Randomly, Norton Security decides it doesn't want to load when I turn on the computer. No error message, it just won't do anything. Interestingly enough, the last time it happened, I did the Windows Compatibility Issue test, and Windows claimed the program was incompatible. Again, this was done during a time Norton was refusing to start. Not sure how, given how during the last reinstallation, I followed the prompts and downloaded the correct version.
Rebooting gets it to work, but I'm tired of having to reboot.
