Course Practice lab

The scary pop-up

Best ending

Done right. The warning was a web page, not your computer talking. You closed it without engaging, and did not bring it back.

The lesson: Real security warnings never ask you to call a number (FTC). Task Manager (Ctrl + Shift + Esc) or Force Quit (Option + Command + Esc on a Mac) closes a page that will not let go. If it keeps coming back, have the browser checked.
