What avast version are you using latest being 17.1.2286 ?
I’m running the latest beta version 17.2.2287 and opening the virus chest doesn’t show a Scan button.
If you select a file and right click it has many options, Scan is just one of them, but that doesn’t work for me either.
It looks like that is a bug that hasn’t yet been squashed.
