How to remove malware from a Mac

in Apple

Here’s what to do if you suspect you’ve already installed malware on to your Mac – typically because a website claimed to have detected problems. Follow these steps to remove the software:

  1. If the app is open, check the name of the app.
  2. Move or close the app window.
  3. Open the Utilities folder (Command-Shift-U).
  4. Open Activity Monitor.
  5. Choose All Processes.
  6. Go to the Utilities folder in the Applications folder and launch Activity Monitor.
  7. Look for an app called MacDefender, MacSecurity or MacProtector. Or look for the name of the app (from Step 1).
  8. Click the Quit Process button (top-left) and select Quit.
  9. Quit Activity Monitor.
  10. Open the Applications folder and locate the app (called MacDefender, MacSecurity, MacProtector, or some other name).
  11. Drag the unwanted app to the Trash. Empty the trash.



Malware also installs a login item in your account in System Preferences. Removal of the login item is not necessary, but you can remove it by following the steps below.

  1. Open System Preferences, select Accounts, then Login Items
  2. Select the name of the app you removed in the steps above ex. MacDefender, MacSecurity, MacProtector
  3. Click the minus button
