I have the same problem on Windows 10.
Norton Antivirus doesn't start. I start it manually. Then after a few minutes, I get a "Norton Autofix, Restart required" message with the following information:
Norton Security
22.24.3.2
8504, 101
BucketID: D43D292E
Windows 10 Home
19041.1.amd64fre.vb_release.191206-1406
Norton Autofix Results: 2 item(s)
Installation :: Restart Required
LiveUpdate :: Failed
The Autofix doesn't work.
I've reinstalled Norton twice with the same results.
Norton works after the reinstall. It fails after updates are manually applied.
