I have A toshiba laptop running Windows 8.
I had to uninstall and reinstall NIS 21.5.0.19 because I received ERROR 3039,1 and Error 8506,421
After reinstall of NIS when I open Internet Explorer 10 and look under manage add-ons, Norton Vulnerability Protection is disabled. I enable it but when I close Internet Explorer and reopen it Norton Vulnerability is back to disabled.
Any Suggestions would be appreciated.
