Apple.com-speed-macos.live is a social engineering attack directed to less experienced users. Bad actors behind the site are trying to convince victims that their macOS computers are infected by 3 viruses and must be immediately fixed.
The fake pop-up message that users encounter on Apple.com-speed-macos.live domain reads as follows:
