Password forgotten problem

Yes, Adhem. We're afraid as the setting password can't be reset. Instead we can remove a specific file to regain access to the program without a password.

To do so : Boot your computer in safe mode - Navigate to : C:\Program Data\AVG\Antivirus\ - Locate & delete the file aswResp.dat - Restart in normal mode.

Note : Program data might be hidden. To get to the folder, please type %programdata% in runline command. To get runline command box, please press Windows logo key & R key together.

You can also check this article which has the screenshots & steps to remove the file. 
If the above method fails, we may need to uninstall AVG using AVG Clear & then reinstall AVG.
