  • 3. Remove the Search Marquis Extension — Go into your browser settings, click on extensions, and remove Search Marquis. You may also have to reset some settings and change your homepage — read my full guide to see how.
  • 4. Stay Protected — Invest in a high-quality internet security suite to avoid further viruses and infections.

Search Marquis is a browser hijacker that commonly affects Safari and Chrome users on Mac computers. Any time you open a new window, Search Marquis navigates to a handful of websites that generate ad revenue for hackers. Search Marquis is also known as Search Baron, which is an older version of the same browser hijacker.

There are several signs that indicate you have Search Marquis on your computer. Most users notice they’ve been hacked by Search Marquis because the homepage in their browser has been replaced with, and their browser won’t let them change their homepage back. In addition to redirecting your searches and inserting suggested searches into the Bing search bar, Search Marquis also collects user data, sharing all of your browsing and search information with hackers.

Search Marquis runs as a browser extension, but it’s usually installed in your browser by malware running on your desktop. What this means is that you will need to run an antivirus scan to remove the Search Marquis files from your desktop and also manually remove any trace of Search Marquis from your browser in order to completely remove this browser hijacker from your system.

I recommend most users download Intego, which consistently scores the highest ratings in our malware detection tests for Macs. However, Norton is also an excellent antivirus program for Mac users. All of these programs are offered with money-back guarantees, so there’s no risk involved in giving them a shot! With a good-quality antivirus installed, you can remove Search Marquis from your system in less than an hour — here’s how!

Risk-Free For 30 Days — Try Intego Now

Step 1. Run a Full System Scan With Your Antivirus

IMPORTANT: Do not connect your cell phone, tablet, or USB drive to a computer you suspect is infected. In doing so, you risk any infections replicating themselves onto those devices.

After downloading a secure antivirus suite like Intego, run a full disk scan on your computer. A full disk scan will detect, quarantine, and remove every virus it finds on your system, such as spyware, rootkits, and worms that can often run undetected — including any files associated with Search Marquis and Search Baron.

Step 1. Run a Full System Scan With Your Antivirus

The full scan can take anywhere from 1–4 hours because your antivirus needs to analyze every single file and process on your computer. Once it’s done so, it will alert you that the scan is finished, and you can be confident that every piece of malware on your system has been identified and put into quarantine.

Remember: Run the full system scan until it’s finished. DO NOT cancel the scan when you see a virus appear on the infected file list. There’s no way of knowing how many other copies of a virus exist in your system.

Step 2. Delete Any Infected Files

Your antivirus will give you the option to delete compromised files after it has identified and quarantined all of your compromised them. Advanced users can go through the quarantined files and make sure there are no false positives before hitting the Delete button. But most users will just want to trust their antivirus software — if it’s been flagged as malware by a program like Intego, chances are you don’t want it on your device.

Step 2. Delete Any Infected Files

It’s a good idea to restart your computer and run a second full system scan once you’ve removed any compromised files from your system. Just like the first scan, it’s important to let this second scan complete. Once the scan is finished and you’ve reviewed and deleted compromised files in your quarantine folder, your disk will be 100% malware-free — but you’re not finished with Search Marquis yet!

Step 3. Remove Search Marquis From Your Browser

Now you have a few options to remove what’s left of Search Marquis from your browser. It’s pretty simple:

Step 4. Keep Your Device From Getting Re-Infected With Malware

New malware is released every day, with increasingly inventive methods of infecting unsuspecting users. You also need to keep yourself safe from data breaches, identity theft, and more.

How can you keep your devices and data safe? There are several things you can do:

  • Keep Your Software, OS, and Drivers Up-To-Date. Hackers often exploit vulnerabilities in outdated software and drivers, but antivirus programs like Intego can scan for and update any outdated software, patching those vulnerabilities. It’s also a good idea to regularly check your Mac’s System Preferences menu for any outstanding macOS updates.
  • Don’t Download Suspicious Files. Whether it’s from an email or a suspicious website, don’t download files unless you’re 100% sure you recognize where they’re coming from. Even if you do recognize where they’re coming from, you should only download files if you have a good antivirus program running in the background.
  • Secure Your Wireless Network and IoT Devices. Ensure your wireless network and IoT devices are password-protected. If they’re not, use a good password manager like 1Password to generate and store super-strong passwords for them. Also, ensure your antivirus has a decent firewall. All of our recommendations below include a pretty good firewall.
  • Install a Secure Antivirus Program. Only a few antiviruses provide all of the security protections you need to stay safe online, and I can honestly say Intego is the best choice for Mac. It uses advanced machine learning tools and a massive malware database to keep malware off your device. Below are some more top picks.

How to Manually Remove Search Marquis

Manually removing Search Marquis from your computer is a multi-step process that requires a good attention to detail. It’s important to follow these steps carefully to ensure complete removal and to avoid potential damage to your system. That said, if you’re not confident, I strongly recommend using an antivirus instead.

Step 1: Uninstall Suspicious Applications.

Open the Finder app and go to the “Applications” folder. Look for any applications that seem suspicious or that you don’t recall installing. Right-click (or control-click) the application and select “Move to Bin”. Proceed to empty the Bin.

Note: you can also drag and drop the item into the bin on your taskbar.

Step 1: Uninstall Suspicious Applications.

Step 2: Remove Search Marquis from Browser Extensions.

In Safari, go to Preferences in the menu bar. Click on the Extensions tab. Find any extensions you don’t recognize and click Uninstall.

Step 2: Remove Search Marquis from Browser Extensions.

Likewise, if you’re using Google Chrome, Firefox, or Edge, click the puzzle piece icon on your toolbar and click Manage Extensions.

Note: if you can’t see the puzzle piece icon, click on the drop-down menu first (3 dashes or dots in the top right corner, depending on your browser), and then click Extensions/Add on and themes.

Step 2: Remove Search Marquis from Browser Extensions.

Look for any unfamiliar extensions that could be related to Search Marquis. Click Remove to uninstall them. Don’t simply toggle them off, as this will disable but not remove Search Marquis from your browser.

Step 3: Reset Browser Settings to Default.

If removing the suspicious extensions doesn’t resolve your issue, you need to reset your browser’s settings to ensure all changes made by Search Marquis are reverted (if it did fix your issue, you can jump to step 4). Just be aware, resetting your browser settings will also delete all extensions.

In Safari, go to Preferences, and then Privacy. Click Manage Website Data and Remove All.

Step 3: Reset Browser Settings to Default.

Go back to Preferences, select the Advanced tab, and tick the Show Develop menu in menu bar box.

Step 3: Reset Browser Settings to Default.

Then, in the menu bar, click Develop and select Empty Caches.

Step 3: Reset Browser Settings to Default.

In Google Chrome, go to Settings, then Reset settings. Click Restore settings to their original defaults, and confirm your choice when prompted.

Step 3: Reset Browser Settings to Default.

In Mozilla Firefox, go to Help, then Troubleshooting Information. Then click Refresh Firefox at the top right.

Step 3: Reset Browser Settings to Default.

Step 4: Check Your System for Malware.

Even after you’ve finished with the manual removal of Search Marquis, it’s a good idea to run a full system scan using a reputable antivirus. Once you’ve done this, you can move onto step 5.

Step 5: Modify Hosts File (Advanced).

If Search Marquis has modified your hosts file, you need to revert these changes manually.

To do this, open Terminal and type sudo nano /etc/hosts and press Enter. Enter your password when prompted. Now, look for any entries related to Search Marquis and delete them. Finally, press CTRL + O to save changes, then CTRL + X to exit.

Step 6: Monitor for Re-Infection.

To avoid problems with Search Marquis in the future, keep an eye on your browser and system performance for signs of re-infection. Regularly update your security software and practice safe browsing habits to prevent future infections.

Note: Manual removal can be effective, but there’s always a risk of missing something. If you continue to experience issues, consider seeking help from professional malware removal tools.
