Hello Sm9

Have you tried to restart your computers to see if it fixes the issues? Norton requires a complete Shutdown and Startup. To accomplish this, You have to use Restart and not Startup. Please see this link.

Here is a link for turning off Fast Startup in Windows 10


Hope it helps.


Success always occurs in private and failure in full view. Windows 10 Pro 64 bit Norton Core Security Plus Core Firmware 282 I E 11 Chrome latest version.
