Lastly, Clean up Browser Settings and Data

The search marquis may have infected not only Safari but all other browsers on your mac computer. The instructions below must be applied to all browsers you are using on your mac.

  2. Check if your Homepage field is the same as you have entered.

  3. Choose the Time range from the drop-down.

    I’ve gone through this and other tutorials. Nothing seems to work. What am I looking for in the activity monitor? Can’t seem to find anything sticking out as malicious?

      Hello Lesham, If there is nothing suspicious in the Activity monitor, then skip the last steps where you need to clean up the browser data and set a default home page. Also, make sure to have the right search engine setup in the Safari browser.

    This is how i got rid of this menace.

    check if you see this process in your Activity Monitor : LearningNumbers-GamesforKids2

    When i tried to kill using kill -9 it just came back up.

    Next, go to the folder : /Users/Library/Application Support/ :

    Do you see any folder CarbonCopyCloner5 ? If you do, move it to the Trash.

    Try to fore quit any LearningNumbers-GamesforKids2 processes. This procedure helped me get rid of searchMarquis on my iMac.

  8. James

    I tried all of these steps and they didn’t work because it said I had no extensions. I found an application online called CleanMyMacX, downloaded the free trial, they scanned my Mac and detected potentially malicious viruses, and gave me the option to remove them. Now search marquis is gone. Hope that helps.

    1. Editor Staff

      Thanks for the recommendation, James! Do this free trial requires registering an account?
