Sometimes Mac users see suspicious apple.com-fast.live pop-ups that keep bombarding their browsers. This is the problem specifically for Mac browsers – Google Chrome, Mozilla Firefox and Safari. Note that the intention of these alerts is to force you into downloading and installing a lot of malicious programs, such as fake system optimization tools and even rogue security utilities.
