Whenever AVG downloads a virus database update, Anti Track disconnects from the licence (I have the AVG Ultimate bundle). Restarting the app, all of AVG, or the whole PC has no effect. Using the licence number of the package for Anti Track alone does not work; Anti Track declines it as invalid. Trying to re-activate the whole package or log-off and log-on to the account from the app after the initiated PC restart after that does not work either.
The only thing that works is to reinstall the whole package. And if the next day comes a new database update, I have to reinstall it again.
