Avast Pro stopped working

No reason that I can fathom out either.

The logo in the taskbar has a red X on it and when I click it I get a pop up that tells me that

“YOU ARE UNPROTECTED” Avast background service is not running Start Now

But when I clitk do that nothing at all happens. I’m loathe to uninstall and download gain in case I lose my subscription account.

Any advice ? thanks.

And if you reboot?

If no success try avast repair option from Ad/remove programs > avast > Uninstall/Change > repair…
