Just happens about 2 days ago. Before I go and do a system restore, I would like to know if there is a quicker way to fix this annoying popup at the bottom of the screen. It appears as soon as I open IE10. I don't have to logon to any website. I have tried Tools > Internet Options > Security > Custom level > under Miscellaneous check the Enable box at "Don`t prompt for client certificate selection". I have also tried to Reset Internet Explorer. The damn popup still shows up.
