The message you see may be slightly different than this. The message may also tell you to call a 1-800 number. The message has the Apple Care logo to trick you into believing that the message is an official Apple warning message.

This is a tech support scam. The alert is not coming from Apple or Apple Care. Do not call the number or do not click Scan Now. You should not interact with pop-ups or webpages that seem to take over your screen. These web sites and messages are designed to steal your personal information. Just ignore everything what the message says and do the followings:

What you should do is to quit your browser. Here is how:

  1. Force Quit from the Apple menu in the upper-left corner of your screen. Or you may press Option, Command, and Esc (Escape) together
  2. Select Safari (or Chrome) in the Force Quit window
  3. Click Force Quit.
  4. Now press and hold the Shift key while reopening the Safari app. Doing so will tell Safari not to load any sites from the last session.

If you are using Safari, turn on security settings. Here is how:

  1. In the Safari app, click Safari (Safari menu bar)
  2. Click Preferences
  3. Click the Security tab
  4. And then select the “Warn when visiting a fraudulent website” box.

Safari Security settings

When you check this setting, Safari will warn you when you are visiting a phishing web site.

Furthermore, you may want to remove stored cookies and other data on your Mac. Here is how:

  1. In safari, go to Safari > Preferences > Privacy
  2. Click Manage Website Data
  3. Wait a few seconds for web site data to load
  4. Click Remove All

If the steps above does not work, disconnect your Mac from the Internet, and delete cookies and other data and reconnect to the Internet.

  1. I once visited a valid French site for some information. As soon as I got there, I got a warning. Not this one, but similar enough. There was no way to close the page, or even close the browser. So, yes, I went to the Force Quit menu to close the app. By the way that won’t always work either, you have to turn the computer off.

    But this did work. I then went to cached sites, and deleted the last site I was at, and that solved the problem. I tried it again, just to be sure it was on that site, and sure enough, it was. Same thing to get rid of it.
