Norton Internet Security 2013 Error: 8506, 421
I see that other people are having similar issues with NIS 2013 "Autofix" failing and generating
Error: 8506, 421. I'm hoping that making a separate post on the problem will generate
some positive action from Symantec.
My problem seems identical to what many others are experiencing. After a clean install upgrade
to NIS 2013 from 2012, back in October, I began to experience the missing taskbar icon issue. The
rollout of version 18.104.22.168 appeared to resolve that.
About 10 days ago the taskbar icon disappeared. A reboot restored it and all seemed
fine for a few days until a LiveUpdate session generated "Error: 8506, 421".
I rebooted and the problem reoccurred the following day.
Yesterday I followed the advice on the Symantec website and ran the Norton Removal and
Reinstall tool. Today the problem is back.
The error message generated by the Autofix fail pop-up reads:
Norton Internet Security
Error: 8506, 421
Windows 7 Home Premium
Norton Autofix Results: 0 item(s)
All other programs are working fine and I can detect no other
issues with my computer. The only program that keeps failing
is NIS 2013. Having an unreliable AV program in this day and
age is unacceptable.
I'd welcome any suggestions on how to resolve this.
