You are surfing the internet and a pop-up appears stating your mac is infected, or a problem exists in some form. The pop-up states you need to call a specific telephone number in order to solve the problem. First of all do not call the scam telephone number in order to solve the problem. These support scams are expensive, do not solve the problem and might even cause more problems.

There are many examples available on the internet of users that experience these kind of scam pop-ups, they are not only for Mac OS but also for Microsoft Windows and even Android mobile phones and tablets. What ever happens, do not call the support telephone number. Restarting the computer seems like a reasonable solution but the pop-up might appear when you restart the Safari browser.

Scam pop-ups might occur when you visit a compromised hacked website, cybercrooks seem to inject compromised websites with their malicious code and redirect your browser to a scam support pop-up. The good thing is, these pop-ups are scams they are not actually malware on your computer. These pop-ups are only used to scare the user into calling a deceptive telephone number in order to make money or steal personal information.

Remove Safari pop-up Scam (Fake Alerts)

Here are a few example or scam pop-ups:



Solution 1: Close the tab or pop-up

  • When a pop-up appears, click it’s OK button and select the checkbox “Don’t show more more alerts from this webpage“.


  • Now close the tab causing the pop-up (doesn’t always work!) for example using “Command + W”.

Solution 2: Force quit Safari (or another browser)

Sometimes a pop-up scam prevents shutting down your browser or closing a tab by using javascript code or a authentication dialog. It’s just not possible to click anywhere in the screen and the browser is locked with the scam message.

  • Try pressing the “Command ⌘ + W” button at the same time. Try closing the window, it’s not very successful in most scams but worth a try.


  • Try pressing the “Command ⌘ + option + ESC” button at the same time and select “Safari” from the window and press the “Force Quit” button.


If these techniques are successful there might be another problem. As soon as you open Safari the tab with the pop-up scam will open again.

How to prevent the scam tab for opening again?

  • Hold down the “SHIFT” key and open Safari. This will prevent Safari from opening windows that were open when Safari was forcibly closed.
  • Disconnect from the internet and open Safari. Navigate to a legitimate website e.g. and connect again to the internet.

Solution 3: If nothing worked…and the pop-up still opens.

Reset Safari is the only option left, make sure Safari is closed.

  • Goto Finder
  • Goto Go > Go to Folder


  • Type the following: ~/Library/Preferences


  • Find a file named: and remove it (drag to trash)


  • Goto Go > Go to Folder
  • Type the following: ~/Library/Saved Application State


  • Find a folder named: and remove it (move to trash).


  • Goto Go > Go to Folder
  • Type the following: ~/Library/Safari


  • Find a file named: LastSession.plist and remove it (move to trash).


  • Open Safari and the pop-up should be gone. If you experience the follow message select “Don’t Reopen”.
