The main window shows warning icon with text "Avast Free Antivirus has expired". There are a whole of three buttons to renew it: red "ACTIVATE" on the left, green "SELECT PROTECTION" in the center, green "REACTIVATE" on the bottom panel. Each of those opens "Select you security level" dialog with two options: "Avast Free Antivirus / Your current protection" (white "SELECT" button) and "Avast Premium Security" (green "SELECT" button). Clicking the first button for the free version shows a dialog "Thank you for activating Avast Free Antivirus / Your loyalty pays off -- 73% OFF", I close it. The main window continues to show "Avast Free Antivirus has expired" and does so after a reboot. This has been going on for months. Reinstalling does not help.
