Search Marquis

Search Marquis is a rogue search engine that hijacks the homepage of Mac browsers, changing it to Search Marquis enters the system via app-bundles and seeks to promote certain websites and ads through aggressive automatic page-redirects that it causes in the hijacked browsers.

Many users refer to this hijacker as a virus, but that’s not technically correct because, although Search Marquis could indeed make unwanted changes in the browser and control its behavior without your permission, it is not capable of harming your Mac or spreading to other parts of the system. That said, you are still strongly advised to delete this hijacker alongside the app that brought it to your Mac and also revokes any changes that it may have made in your Safari, Chrome, Firefox, or another browser.

What Is Search Marquis?

As we already mentioned, the moment this browser hijacker gets installed on the computer, it automatically changes the homepage of your main browser to the address. At first glance, this may look like a regular search engine but in reality, Search Marquis cannot perform any online searches.

What is Search Marquis
Many users ask “what is Search Marquis?”, once they are infected with it.

Instead, if you use it to search for something on the Internet, when you select the Search button you will be taken to a Bing search results page. Getting rerouted to Bing is obviously not a problem because the latter is a legitimate search engine, but this could be a bit irritating if you prefer to use, say, Google or Yahoo as your default search engine option. The real problem here, however, is what happens between the moment you start the search and the moment you land on the Bing page. Though it may seem like you get redirected to Bing instantly, this is not quite true. Before it gets to Bing, your browser would actually rapidly get rerouted through a series of other websites that it would only visit for a split second, so you may not even notice this. In reality, this is the main goal of the hijacker – to take your browser through those other sites, thus artificially gaining them more views and boosting their ratings. This might seem harmless, but you should know that some of those intermediate sites could be hazardous and unsafe. They might gather data from your browser or even target you with malware despite the fact that your browser is only visiting them for a fraction of a second. Therefore, the presence of Search Marquis on your browser is not to be underestimated – even though the hijacker itself is not capable of causing damage to your Mac, the threats it may potentially expose you to (threats such as Trojans, Rootkits, Ransomware, and Spyware) can be quite harmful to your computer and virtual privacy.

Other problems with Search Marquis

This aggressive hijacker may also cause additional issues that make it even more unwelcome. It may spam the screen with adverts and banners, some of which may be disguised as warning messages from your system claiming that you need to download and install some (fake) security app that would make the (non-existent) problem go away. Also, the hijacker could install helper elements in the system and the browser (such as rogue browser extensions) to gain more control and persistence and thus become more difficult to uninstall. Last but not least, you must also not forget that most hijackers tend to gather info from the browser and then sell it to third parties who may use it in potentially harmful ways without your knowledge.

With all that said, it should be apparent that the only viable action for those of you who have Search Marquis in their computers is to uninstall the unpleasant hijacker, which is what we are going to show you how to do in the following removal guide.

How to Get Rid of Search Marquis

To get rid of Search Marquis you should start with quitting its process and deleting the app that caused it to get installed on your Mac.

  1. Go to Finder, open Applications > Utilities, then start the Activity Monitor, and find and Quit the hijacker process(es).
  2. Next, to get rid of Search Marquis, go back to Applications and there try to find and uninstall the rogue app that got this hijacker in your system.
  3. Click on the Apple logo menu, go to System Preferences > Users & Groups > Login Items, and there remove any suspicious items you are not familiar with.
  4. Lastly, from System Preferences, go to Profiles and delete all Mac accounts that you don’t recognize.

Those short four steps are a quick way of getting rid of the hijacker that would hopefully work for most of our readers. If, however, you need more detailed instructions and/or if completing those steps didn’t rid you of Search Marquis, below we have prepared a more in-depth explanation of how to uninstall this unwanted hijacker where we’ve included some extra steps to ensure that nothing from it would remain in the system.

Detailed how-to get rid of Search Marquis Instructions

  1. From the menu bar at the top of your screen, select the Finder button and then click on the Applications icon that’s in the left sidebar.
  2. From the Applications folder, go to Utilities, and there open the Activity Monitor app.
  3. Look through the listed processes and try to find the one that has been launched by Search Marquis. The process will likely not have the same name as the hijacker so use your own discretion to figure out which one it is. Here are some tips on what you need to be looking for:
    • Processes with odd names that seem out of place or are unfamiliar to you.
    • Processes that are using up large chunks of your system resources (RAM, CPU, battery life) without being related to any program that’s currently running on your Mac or any important system function.
    • Processes that appear only when the browser is running yet have different names from the other browser processes.
  4. If you have a high level of certainty that a given process could be linked to the hijacker, select its entry in the Activity Monitor and then click on the button in the upper-left corner to quit the process.
    • If you are unsure about whether you must quit the process that you suspect, try to find more information about it on the Internet by searching for its name – in most cases, if it is an unwanted process, that should show up in the search results.
      Activity Monitor Mac
  5. After you stop the suspected process, return to the Applications folder and there try to find an app with which you think the hijacker may have been bundled – app-bundling is one of the most common distribution methods for hijackers like Search Marquis so this is likely how it got on in your system too.
    • Note that apps that have been downloaded from third-party sources (rather than from the official Apple App Store) are more likely to carry hijackers that have been bundled with them due to lower security standards in most third-party app download platforms.
  6. If you think you’ve figured out which app must be removed, drag it to the Trash icon on your Desktop and then empty the Trash.
  7. Next, select the Apple menu from the top-left of your screen and go to System Preferences.
  8. Select the Users & Groups settings and then go to Login Items.
  9. There you will see the different apps that are automatically launched when your Mac starts – if any of them seem sketchy or you think could be linked to Search Marquis, remove them from the list by clicking on them and selecting the minus button below the list.
    Maclogin Items
  10. Again from System Preferences, select Profiles and remove any profiles from the list that haven’t been created by you or by other admins of the computer.
    • Note that even if the profiles seem to have legitimate names such as “Safari settings” or “Chrome settings“, they should still be removed unless you or another admin has purposefully created them.

      • Hi Cal Benton,
        yes we recommend ComboCleaner and its a trusted program. You can download it and use its trial version to remove the malware from your Mac.

    • Hey Brandon, I followed this article (remove search marquis virus mac) up until the point when it told me to go to the action monitor and take a sample of any “suspicious processes.” I am able to take the samples, but I don’t know what to do with them. How do I analyze these samples to know whether or not I should delete them?

      The search marquis has gotten quite out of hand at this point. I am automatically redirected to it every time I open a new tab, or even if I click the back button to return to my google search results. I have removed it from all settings that I can find, yet still the problem persists. Thanks for your help.

      • Hi Dan, I believe you sample any of the suspicious processes so you can find the paths to the files related to these processes, you can use the online virus scanner on the page to confirm or deny your suspicions.

    • Hi Petkov, where is this online virus scanner , please? If it is combocleaner, this function is no longer free and I am unaware of it it’ll remove completely if I pay.

      • Hi Emily, I presume you have followed the removal guide in this article. Can you please be more specific which step is giving you trouble?

    • I am getting a message “You can’t open the application “SpyHunter-Installer.exe” because Microsoft Windows applications are not supported on macOS.” Please advise.
