I just renewed my licence at the beginning of this year.
However about three weeks ago Avast fails to start.
When it normally launched upon system startup and Avast service was set to run automatically - it's no more.
Whenever I attempt to tick Avast antivirus box at startup programs - it automatically unticks after hitting apply.
And when I attempt to start Avast via Services, I get "operation failed" message.
Is it the result of some malicious process/service? What shall I do - reinstall Avast or install a different antivirus?
