Bank Mode disappears before it opens. The tab shows for a few seconds, then disappears. I have done every step Avast lists, nothing works. And everything has been uninstalled, and installed, updated, restarted, the lot. I even did someone's suggestion to put Avast into passive mode, reboot. Nothing. I have tried to open it from all angles, and the tab shows for a few second then disappears. I would appreciate a fix for this. Thank you, joan
