You Are Unprotected

my App says "You are uprotected and the avast service is off’ after i update the latest version

Have you rebooted since ? Also did you upgrade from V8 to V9

Same issue here… And yes, I have rebooted. I have also “repaired” the installation as suggested by others and then rebooted. Same problem.

If you upgraded from V8 to V9 then
