Hello.
Few months ago I wrote about problem in this thread: https://community.norton.com/en/comment/5363833
Bug remained the whole time, but recently it became very bad. Norton doesn't start almost every boot. (I can run it, by few start\stop of ns service manually)
But now after os starts, "Norton Autofix" window appearing with error 8506, 421. It trying to find the problem but hangs on "checking installation" step (I waited very long and nothing happens).
I did everything: reinstall ns (according to instruction), reinstall Windows, changed some hardware since then.
Do you have any solutions?
