When search marquis gets installed in your Safari, it changes some settings without permission, such as search engines on our home page, adding new tools to your browser, and other fake buttons.

Additionally, it starts displaying frustrating ads on the whole screen in pop-up ads, banners, boxes, and other promotional materials that stick on a screen like a newly married couple.

Some days ago, unknowingly, I installed the search marquis program in my safari browser. And it’s been killing me since then. Nobody would like to keep such idiotic things, I tried many guides, but none worked. However, I found one method that worked. So if you are facing this problem, read this article until the end.

For your comfort, I have explained everything in detail in a divided process to remove search marquis from your Safari mac in 5 easy steps to ensure you don’t skip any.

Force Quit the Safari

If your Safari browser is opened, the first thing you need to do is quit it. If you have trouble closing it usually, you must force quit the browser.

Here are the steps to Force Quit the Apple Safari browser on Mac Computer:

  1. Click on the Apple apple logo logo for options.
  2. From the options list, click on Force Quit… (another way is to press the Cmd + Option + Esc key).
    Apple macOS System Preferences
  3. Force Quit Applications window will pop up.
  4. Then select the Safari app within the window.
  5. Hit on Force Quit button and close the window.

This will close the Safari browser from the background and terminate all running process threads. Note that you should use this option only when Safari cannot close by Close action.

Find and Delete Malicious Files

Start Activity Monitor by launching Finder and going to Application > Utilities > Activity Monitor.

Activity Monitor Location

Once you are there, start analyzing all the processes; if you think any process can be part of hijacking, highlight that process and click on the ‘I’ (information) button at the top to open up the following box.

In the case of Google Chrome, you can find the process information in this format.

Now click on the Sample command button at the bottom to open the Sample Text of the application.

Do this for all processes you think are part of hijacking and quit the malicious files process from the activity monitor.

Note: Be extremely careful while deleting files or quitting the process. You may damage your system if you delete the wrong file.

Check Browser and Prevent Hacking

Now that we have cleared the hijacked processes, we will check if everything is working fine.

  1. Press the shift key while launching Safari again.
    Pressing the shift key will prevent the previously opened pages from relaunching in Safari.
  2. You can release the shift key once Safari is safely launched.

If you still face trouble closing unwanted pages in Safari, you will need to take additional steps.

  1. Force quit Safari again.
  2. Turn off the WiFi connection from Mac’s menu.
  3. If you are using an ethernet connection, disconnect the ethernet cable.

This will kill the connection between the hacker and your safari browser.

Delete Marquis Search Extensions

There is a high chance that a browser extension might be causing the issue of injecting malicious sites. In that case, you should quickly identify and delete the extensions from the Safari browser.

Here are the quick steps to delete the extensions from the Safari browser on a Mac computer:

  1. Launch the Safari Browser on Mac while holding the shift key.
  2. After the successful launch of the Safari browser
  3. Click on Preferences from the Safari menu. This will open a new Preferences window.
    Safari Preferences Menu
  4. Switch to the Extensions tab.
    Safari Extensions tab with third-party extensions disabled
  5. Within the Extensions tab, select the extension you think might be malicious.
  6. Click on the Uninstall button.

This will remove the extension from the Safari browser and also delete all malicious activity. However, If you are unsure which extension to remove and don’t want to take any risk, you can uninstall all extensions.

Also, if you do not plan to use any extension, then make sure to turn OFF the option. Third-party developers create extensions to customize and enhance your web experience, as shown in the above screenshot.

Clean up Browser Settings and Data

The search marquis may have infected Safari and all other browsers on your mac computer. The instructions below must be applied to all browsers you use on your Mac.

Since we are talking mainly about the Safari browser, the steps below will be applied to Apple Safari. However, similar options will also be available for other browsers installed on your computer.

Clear Website Data

The first thing that we need to do is to delete all browsing data from our safari browser so that any traces aren’t left in the browser. Clearing the website data will delete all the storage, cookies, and cache from the browser.

  1. Open the Preferences option from the Safari menu.
  2. Switch to click on the Privacy tab.
    Safari Browser Privacy Preference
  3. Open the Manage Website Data… option.
  4. Now click on Remove All Website Data and confirm it by clicking on Remove Now

Note: Remember that after following the above instruction, you will lose all your stored website data and need to sign in again for all websites.

Default Homepage Set up

Next, we will ensure that the default Homepage is set correctly on the Safari browser. We just wanted to ensure that the marquis search isn’t the homepage of our safari browser.

  1. Hit on the General tab in the preferences menu.
  2. Check if your Homepage field is the same as you have entered.

  3. If something else, change it to whatever you want to see first when you open Safari – preferably a search engine like Google.

Clear Browsing History

Lastly, we will delete all the browsing history so you won’t accidentally open a problematic web page again.

  1. Within the Safari browser app, go to the History menu.
  2. Click on the Clear History menu at the bottom.
  3. Choose the Time range from the drop-down.
  4. Hit the Clear History command button.

  1. 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?

    1. I tried everything.then as a last resort I upgraded to Catalina os from Sierra now no problems. but download from app store. the first time i tried it was from apple link didn’t complete .

  2. All these steps don’t work. I created a new user and transfered all my data from the infected user and deleted it. Thank me later when u try this

      1. Hi Nada, the “new user” means the new user login on MacBook. You can create new users under the Users and Group settings page.

  3. i have tried every thing suggested…and open empty pages and black histories…but it is like the cat that keeps coming back…i am going to quit using mac…go with samsung

  4. 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.

    All the best

  5. 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.
