Hi there! It seems a similar problem has been reported already in the past, for example here: https://support.mozilla.org/en-US/questions/954186 Chances are that you have advanced security software on your computer that you're not using (Password Bank), which can possibly be removed from your computer (because it looks like you're not using it). I suggest finding the control panel for your computer and removing Password Bank from your system, if you know how to do that.
