Many commercial or free antivirus and internet security applications will offer some sort of built in protection. This is to stop unauthorized users from tampering with the settings of the program or disabling its functions. It’s especially useful if the computer is used by children or less experienced users. They cannot inadvertently leave the computer more vulnerable by disabling real-time protection or altering other configuration options which could weaken security.
While generally a good thing, it can also lead to issues if there’s a problem with the password stored by the software. Avast Antivirus and Internet Security is one such range of software that has this ability and has been able to restrict unauthorized users from changing its settings for some years. This is done by setting a password to protect the required areas of the program, then anyone else trying to access a protected area is greeted with a password authorization dialog.

The authorization window will darken the rest of the screen and show just the password dialog.
An attempt has been made to enter a protected area of Avast. This may be a legitimate action, but could also be the result of a malware attack.

Cancel or enter the wrong password and you will be locked out of the areas selected for protection. There are several different parts of Avast that can be protected. Program settings, protection control, protection settings, scan control, scan settings, virus chest control, and backup/restore settings are selected by default when you check the option to apply password protection. The additional areas are update control and general program access. This last option will lock you out of the software entirely unless you know the password.

Back in 2016, Avast acquired AVG software for over 1 billion dollars so it now also owns AVG Antivirus and Internet Security as well. For 2017 AVG released a major update to its antivirus software. It now looks a lot more like Avast Antivirus with some functions also transferred over. The password protection function in AVG is identical to Avast’s apart from some minor cosmetic changes.

Over the years we’ve heard stories of users that have been locked out of Avast even though they claim to have known and entered the correct password. Whether you know the password is correct, somebody else has locked you out or you just can’t remember what the password is, not being able to properly access the software can be frustrating.
To try and find a way around this issue, we analyzed Avast a while back and found out where the password is stored and how to remove it from the system. It will leave your Avast or AVG software free of the password lock. As AVG’s password protection is identical, our methods to get around the issue are the same for both applications.
