Received an alarm & pop up for me to call 877-563-5714 to fix a serious security issue, not to restart computer. Is this a scam?

I'm pretty sure that's a scam. Can you get rid of that page using any of these methods:

  • Esc key (cancels certain dialogs, resizes pages that go full screen using a script)
  • Ctrl+w (close tab shortcut)
  • Ctrl+F4 (close document shortcut)
  • Alt+F4 (close window shortcut)
