Short on time? Here’s how to remove Search Marquis in 2023:

  • 1. Scan Your Mac — Use a premium Mac antivirus like Intego to run a full system scan on your computer.
  • 2. Clean Your Device — After the scan is complete, let the antivirus remove all instances of adware, spyware, and other malware that may have been installed while your browser was hijacked by Search Marquis.
  • 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. Intego is the best choice for Mac — it has a highly effective Mac-specific anti-malware engine, plus other useful features like a system optimizer and parental controls. All Intego plans come with a 30-day money-back guarantee, so you can try it risk-free.

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.

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, McAfee and Norton also make excellent antivirus programs 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!

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.

Once you’ve downloaded a secure antivirus program, run a full disk scan on your computer. A full disk scan will detect, quarantine, and remove every virus it finds on your system, including spyware, rootkits, or worms that can often run undetected — including any files associated with Search Marquis and Search Baron.

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

If your antivirus has identified and quarantined all of your compromised files, it will give you the option to delete 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.

After you’ve removed any compromised files from your system, it’s a good idea to restart your computer and then run a second full system scan. 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 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 Avira 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 (such as Norton).
  • 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. Many options in our list of top 10 best antiviruses have a firewall bundled in them.
  • 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.

3 Best Antivirus Programs for Removing Search Marquis

  • 🥇1. Intego — Best antivirus for Mac in 2023.
  • 🥈2. McAfee — Great scanning capabilities and excellent web protections.
  • 🥉3. Norton — Fast malware scans and great web security

🥇 1. Intego — Best Antivirus for Mac in 2023

3 Best Antivirus Programs for Removing Search Marquis

Intego is my favorite antivirus for Mac in 2023. It comes with perfect malware detection rates, a wide range of security features, a well-designed user interface, and good customer support.

The malware scanner worked really well in my tests. It scanned my entire Mac in an hour and removed every malware sample I’d hidden on my device. What’s more, the scanner is very lightweight, so there was no system slowdown during the full system scan, meaning I could browse the web, stream movies, and play games without interruptions.

I also like Intego’s built-in safe browsing feature — it’s a good way to ensure you’re protected from sites that contain the Search Marquis browser hijacker. The safe browsing feature checks to see if your browser’s anti-phishing settings are enabled and alerts you if they’re switched off (some viruses will attmept to disable your anti-phishing protections to make it easier to target your system).

Intego for Mac also includes:

  • System optimizer.
  • Secure backup tool.
  • Parental controls.
  • VPN (separate purchase).
  • And more…

The system optimizer tool is pretty good — you can scan your Mac for specific junk files, such as caches, downloads, log files, or trash, and quickly remove them. In my tests, I was able to save 4 GB of space on my MacBook Pro, which is excellent. You can also scan for duplicate files, which is a handy way of keeping your machine organized.

Finally, Intego’s secure backup tool is a lot better than Apple’s built-in backup feature. For example, you can schedule multiple backups or backup specific files and folders. Honestly, it’s a really effective way to protect your personal data from malware — including the Search Marquis browser hijacker.

Intego offers several pricing plans, starting from $1.67 / month, but my favorite plan is Mac Premium Bundle X9. It costs $34.99 / year and includes every Intego feature. If you just want to scan your computer after removing Search Marquis, you can also pick Mac Internet Security X9 for $19.99 / year. All Intego plans come with a 30-day money-back guarantee.

🥈2. McAfee — Excellent Malware Detection Rates & Web Protections

3 Best Antivirus Programs for Removing Search Marquis

McAfee provides an excellent malware scanner, along with really good web protections, a ton of additional features, excellent customer support, and more. Its scanner found and removed all of my malware samples during testing, and its anti-phishing tool (WebAdvisor) blocked more dangerous websites than the built-in protections on Chrome and Safari.

McAfee’s security features include:

  • Secure firewall.
  • VPN.
  • Password manager.
  • Performance optimization tool.
  • And more…

McAfee’s performance optimization tool can remove web trackers from your device, speed up your internet, and clear junk files from your computer. It isn’t quite as customizable as Intego’s performance optimization tool, and it only saved me 2 GB of junk files compared to Intego’s 4 GB of junk files — but it still works really well.

McAfee has a wide range of plans starting from $39.99 / year, but their names and features depend on your location. That said, all of the plans are covered by a risk-free 30-day money-back guarantee, which gives you enough time to test all of McAfee’s features and see if it’s right for you.

🥉3. Norton — Fast Malware Scanner + Good Web Security Extensions

3 Best Antivirus Programs for Removing Search Marquis

Norton comes with really good web security tools that can prevent you from downloading Search Marquis. It also includes excellent malware detection rates, a wide range of additional features, and impressive customer support.

Norton uses file-caching technology, so its malware scans are very fast. When I scanned my MacBook, the full scan finished in 40 minutes and found every malware sample (including samples of the Search Marquis virus). This is very similar to the results I had with Intego.

Norton’s security features include:

  • Anti-phishing protection.
  • VPN.
  • Password manager.
  • Parental controls.
  • Dark web monitoring.
  • And more…

Norton’s anti-phishing protection (called Safe Web) is pretty good, too. Like McAfee, it blocked more dangerous websites during my tests than the built-in protections on Chrome and Safari.

Norton’s plans start from $54.99 / year. Norton 360 Standard is a good option for Mac users. It costs $19.99 / year, offers coverage for 3 devices, and comes with Norton’s malware scanner, web protection, VPN, and more.

If you want to extend your coverage to 5 devices, you can upgrade to Norton 360 Deluxe for $24.99 / year, which also adds 50 GB of cloud storage and Norton’s parental controls. Whichever plan you choose, you get a 60-day money-back guarantee.
