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 7 Pro 64 bit NSBU Core Firmware 282 I E 11 Chrome latest version.
