I have the same problem. Avast Free Antivirus told me to renew the licence. Doing so ("jetzt erneuern"), the status "Auslaufend, 3 Tage verbleiben" does not change. I de-installed Avast (Avast cleaner) and re-installed the latest version (17.9.2322 build 17.9.3761.0). After installation the status "Auslaufend, 3 Tage verbleiben" reappeared. What should I do?
