Correct,
I don’t think you can renew a just about to expired license ahead of time. (More than 10 days out.) As stated, about ten days before expiration, you will get a pop-up notice on every reboot, or probably after every four hours, when Avast checks for updates by default. The pop-up will tell you it is time to renew your license.
Than you can go to Registration, by right-clicking in the system tray, or through the GUI and renew your license at that time.
If you ever need to reinstall the program, you MUST re-register using the above method.
