Dear Avast, Forum,
old story with Bank Mode crashes. At first it seemed imputable to the Browser, Avast or Firefox, when the issue arises connecting usb devices (Cellular most) when in Bank Mode or using a wi-fi connection through Roaming (Cellular).
It always crashes when you first connect usb device and then open Bank Mode, sometime when you first open Bank Mode and then you connect the device. At least it seems to behave this way.
Bank Mode freezes for several seconds or more, to end starting flashing Windows Taskbar if you are able to get back to Standard Desktop, or having to restart pc.
Thanks a lot for you attention,
Best regards, Bartleboom
