I've read a lot of the posts in this thread and find them to be no help whatsoever. I recently started having problems with pop-up ads from Avast (which I pay for, BTW) telling me either that I have been signed out or that I need to sign in to continue my premium protection. After "trying" to follow the advice of tech support, who recommended going to SETTINGS and changing the time to zero, I cannot even find the settings tab that you're talking about. And the option is not there under my account settings. I am very close to removing Avast in lieu of something else. Just stop it.
