A tech support scam

This “MacOS is infected” alert is fake. It’s a page used by scammers to try and get people to call the provided phone number. It is not targeted – it’s a pop-up ad that’s spread online indiscriminately. It shows the same warning for each and every visitor. The scammers behind this scam only want one thing: to scare people into contacting them.

The goal of the “MacOS is infected” scam is to convince people that their computer is in danger and that the warning is a genuine Apple Support warning. Calling the given phone number connects you to a scammer who pretends to be an official Apple Support representative. The scammer wants a few things:

  • for you to give them remote access to your Mac by installing remote access software,
  • to convince you that your Mac is infected with spyware and other malicious software,
  • to have you pay money (possibly hundreds of dollars) to have this (nonexistent) spyware removed,
  • scammers want to access your computer because they might want to take some of your personal files.

Overall, the “MacOS is infected” warning itself is not harmful. It is frustrating and scary, but it’s not directly dangerous. However, if you call the given phone number or follow any other instructions given by the “MacOS is infected” scam, then you might be put in danger.
