Q: When starting Safari, I get following error and Safari is stuck.

The address bar says:

    This is a scam, not legitimate.

     

    Click  in the menu bar and choose "Force Quit".

     

    When the Force Quit window opens up, select Safari and click "Force Quit"  button at the bottom.

     

    Relaunch Safari holding the shift key down,
