How to deal with At Risk message

I updated my subscription Norton Antivirus 12 for Mac just over a month  ago. I recently downloaded Norton Security in response to a message that popped up on my computer several days in a row. Ever since I downloaded it, I get a message saying my computer is "At Risk" when I log in and when I open Norton. When I click "Fix Now", it appears to run live update but the At Risk message remains.

When I click the link beside the message, it says "Your vulnerability protections are not up to date. Your Mac may be at risk." When I click "Fix now" it tries to fix the issue but the At Risk message remains. What do I need to do to fix this issue?

Many thanks for any help you can provide.
