If you are still having adware issues after scanning with Malwarebytes Anti-Malware for Mac, removing that adware and restarting the computer, then you may have a bad browser extension.


Try disabling the browser extensions one at time to see which extension might be the issue.



  1. From the browser, go to Extensions.
    • In Safari:
      1. Click the Safari Menu, then click Preferences.
      2. Click the Extensions icon.
    • In Chrome:
      1. Click the Window menu, then click Extensions.
    • In Firefox:
      1. Click Tools, then Add-ons.
      2. Click Extensions on the left side of the page that loads.
  2. Next, begin disabling your browser's extensions one at a time. Do not disable more than one at a time!
  3. After disabling one extension, use your browser as you normally would until either the problem returns or you feel certain the problem is gone.

    Be aware that more than one extension might be causing a problem, so keep an eye out for the details. If certain types of ads stop after disabling an extension, but not all of them, you may have multiple bad extensions installed.

  4. If the problem returns, repeat the process, disabling a different extension. Do not re-enable any previously disabled extensions yet! If the problem is gone, the last extension you disabled was the cause of the problem.
  5. Once you have found the cause of the problem, do not delete the extension yet!

  7. Create a support ticket:
    • In your problem description, include the names of the extensions that were found to be a problem. 
    • Attach the system snapshot from step 6.
    • After that, you can delete them from your web browser.
  8. If you have disabled all extensions and the problem continues, the source of the problem must be something other than browser extensions. Refer to KB article: What should I do if Malwarebytes Anti-Malware for Mac didn't solve my problem? .
