Norton Family message flashing on screen

The following message keeps flashing onto my sons computer screen every 8 seconds and then goes away and comes back again. It is extremely annoying. I have tried to stop notifications and that has not worked. I tried uninstalling the program so I can reload but it wont let me uninstall. Please help as I am ready to cancel my subscription as I have spent many hours trying to fix this problem. I hope you can help.

This is the annoying message.
