I am having a similar problem. I open the Avast secure browser. Click on the Security & Privacy center to access the bank mode option. When I click on bank mode it opens the bank mode screen. Typically when I am in bank mode the desktop turns black behind the screen (no problem there) but then the black screen turns to white. I can access a website such as my bank but when I try to type in my username or password I can't type anything in either immediately or, my ability to type these in is significantly delayed. It's as though the bank mode somehow disconnects my keyboard functionality or delays it. I can SOMETIMES temporarily resolve this after closing out and "updating" my virus definitions & application versions - HOWEVER, having said that, I should not need to do this as my settings are for automatic update and I should always be up to date. It's as though the updates which are supposedly already installed need to be installed again. That may be a separate issue as I have also noticed that the automatic update does not always seem to be working either. (Yes, I have it set for automatic update). I have on occasion needed to manually do an update check/install. The problem started about 1 or 2 Avast updates ago. Never had a problem before that. I keep thinking it's a temporary glitch that will be resolved with a new update but it has persisted now for far too long. Does anyone have an answer or permanent resolution to this problem?
