Norton Security Live Update gives an Update Error

Norton Security Says I am At Risk?

 

This evening when I started my Mac, Norton Security popped up and said that my Mac is at risk because "Your Mac is not set to receive all the latest protection and program updates automatically", which is not correct. Clicking the "Fix Now" button runs LiveUpdate, but LiveUpdate says my product is up to date. Once the "fix" is completed, clicking the "Done" button just takes me back to the original screen that says "attention" Fix this issue. Live Update summary shows the AntiVirus Signatures Vr. 150624037 failed. Last weeks similar issue occurred also 2x times, and 3 items were failing to be updated. I've uninstalled and re-install the product and for 3days everything was OK and it happened again within automatically updating the product after required restart. It's getting slowly so annoying, honestly I've never faced so often problem within my norton products since 10years until 2015.

 

I've also attached a screenshot of the error screen. 

Is there a way to solve the issue without re-install.

 

Thanks for any assistance.
