I have used Avast Free & Secure Browser a long time with no probs. Now the Bank Mode in Secure Browser won't launch. That's the first problem. I checked my Avast Free by trying to launch it-refused to,saying UI Failure,whether I tried from Start Page,desktop or tray icons. So I un-installed the Free and re-installed it. Now I have a further problem,because the Apps list says it is installed,but it doesn't appear on the Start Page and there are no ions at all,so I can't launch it! The Bank Mode still won't work. A perfectly working longterm system suddenly disintegrates! I have the paid Avast VPN but there is no effect whether it's on or off.
