How to configure updater to update Calibre

One of the features I enjoy the most with Free Antivirus is the updater. However, I’ve noticed that my Calibre (64 bit) installation apparently isn’t interrogated by the updater. It’s as if I didn’t even have Calibre installed. Everything on PC (Windows 10 Home) seems to work normally, including both Calibre and Avast. However, it would be convenient to have Calibre included in the list of programs that the updater “sees”. Any suggestions?

Not 100% sure but i think avast consentrate on programs that are security related / often exploited
