I know that.
My problem is that my default browser is not Avast Secure Browser.
With Avast Safezone we could use another browser and, when going to bank websites, the bank mode would open automatically.
Now, with ASB this does not happen.
Previous ASZB was based on Opera but the new one is not. It is Chromium-based but is otherwise new in most respects.
Could be Avast has made Bank Mode availability proprietary to Avast Secure Browser only.
Not aware of a prior setting allowing automatic bank mode in other browsers but that is because I didn't look for it nor did I have a requirement for it. In any case, I was ok with using only ASZB browser for Bank Mode.
You need Avast Free at minimum and ASB browser for this to work.
I can open Bank Mode; setting ASB to default is not required here. Right-click avast icon in system tray and selecting 'Bank Mode' works here.
