AVG not working properly

Hi,

I'm using AVG subscription plan for my PC protection. The program does not work properly anymore. If I hover my mouse on the AVG icon in the tack bar a red square appears saying ''Internet security you are not protected''. But when I double click on this icon to open AVG only a white square appears instead of opening the application. I'm using WIn 10.
When I right-click on the AVG icon in the taskbar nothing happens.

I tried to reboot my computer severa times but it does not solve the issue.
