If you suspect Search Marquis has infected your system, you should immediately scan your Mac with a trusted antivirus. Search Marquis alters your default search engine, redirects your searches to possibly malicious sites, and bombards you with unwanted ads.

Fortunately, eliminating Search Marquis from your Mac’s browser manually isn’t excessively intricate. Nonetheless, this process might result in leaving malicious traces, which could necessitate the utilization of a specialized Mac antivirus program to ensure comprehensive elimination. Considering that the majority of security software isn’t tailored exclusively for Mac systems, I rigorously evaluated multiple choices to pinpoint the most efficient ones.

After testing 25+ top brands, I picked the best antiviruses for removing Search Marquis on Macs. Intego is my top choice as it offers 100% real-time detection against complex zero-day threats. You can use Intego risk-free with its 30-day money-back guarantee.

  • Includes web protection, a powerful firewall, personal backup, and tune-up tools.
  • Compatible with macOS 10.14 or higher and has an app for Windows too.

Intego is the best macOS antivirus to remove Search Marquis and prevent it from hijacking your Mac’s browser. In my tests, it detected all the Mac-specific viruses I had planted on my MacBook like Flashback, CresentCore, and KeRanger. The full scan scanned over 1 million files in about 30 minutes with no major impact on system performance.

Its Safe Browsing feature provides real-time protection against Search Marquis and other cyber threats. It blocked known malicious links in spam emails and pop-up ads that contain the browser hijacker, so I surfed the web with complete peace of mind with Intego. Safe Browsing also ensures your browser’s anti-phishing settings are always on.

In my tests, Intego gave me a 100% real-time protection score. It uses behavior monitoring and heuristic analysis to block unknown and fast-emerging threats before they can hijack your browser. Besides that, Intego offers:

  • Powerful firewall — blocks incoming connections when your Mac is connected to public WiFi to prevent hackers from remotely planting Search Marquis on your device.
  • Mac Washing Machine — includes a range of optimization tools that clean junk files and remove cache from your browser to improve your Mac’s performance.
  • Personal Backup — periodically saves important data onto an external drive or server to keep it safe from potential attacks caused by Search Marquis.
  • ContentBarrier — lets you keep your child’s Mac secure from Search Marquis and other data-stealing malware.

I had no trouble finding features on Intego’s user-friendly interface. That’s because the features are split into standalone apps but are available in a single package if you get Intego’s premium subscription. Intego is available in 20+ languages, including English, French, and German which adds to its beginner-friendliness.

A small issue with Intego is that despite being an Apple-exclusive antivirus, it doesn’t have a native app for iOS. However, you can still scan your iPhone by plugging it into your Mac. But if you want real-time protection for your iOS device, here are some of the best iOS antivirus apps worth checking out.

To get the best value deal, I suggest signing up for Intego’s Premium Bundle. You can protect 1, 3, or 5 Macs for up to 2 years of subscription with tiered pricing. It includes all the 5 apps you need for comprehensive protection against Search Marquis and other complex malware. You can try Intego risk-free with its 30-day money-back guarantee.

MacKeeper’s Adware Cleaner easily removes Search Marquis from Safari and other adware hidden in your Mac apps. It uses a sophisticated scanning engine with deep cleaning algorithms to identify browser hijackers and hard-to-detect adware on your Mac. In my tests, MacKeeper detected my Mac’s Safari was compromised and removed Search Marquis instantly.

With its 100% real-time detection score, MacKeeper can easily remove Search Marquis from your Mac and prevent future infections. It blocked the Pegasus zero-day virus, designed to be invisible on Macs and spy on you. It also prevented me from opening 10 malicious URLs known to contain Search Marquis. Also, MacKeeper protects you with its:

  • Ad blocker — blocks most pop-up ads, including malicious ones that might infect your Mac with Search Marquis.
  • ID Theft Guard — checks if your email address has been compromised in past data breaches, so you can take appropriate measures to secure your accounts.
  • Optimization tools — lets you clear up space on your Mac by removing junk files and apps with a memory cleaner for better RAM allocation.

If you have trouble using any of MacKeeper’s features, check out its online knowledge base as it contains answers to most general queries. If that’s not enough, the 24/7 live chat is the fastest way to contact the support team. I got prompt responses to my queries, but the support agents weren’t always very helpful with technical questions.

I was super impressed by MacKeeper’s clean dashboard. All the features were neatly organized on the left pane, and I saw my Mac’s overall security status in the middle. MacKeeper also showed me recommended actions like cleaning up junk files and turning on Privacy Protection to improve my security score.

My only reservation with MacKeeper is its lack of a firewall. I consider it a must-have to prevent malicious online traffic, especially while using your Mac on public WiFi. However, MacKeeper’s perfect real-time scores compensate for a missing firewall. You can also check out these top antiviruses with rich macOS apps.

All of MacKeeper’s plans have the same features, but you can choose between the monthly or yearly plan with tiered pricing for the number of Macs you want to protect. I recommend the 1-year plan as it offers the best-discounted price of $5.97 per month. You can try MacKeeper risk-free for 30 days with its money-back guarantee.

3. TotalAV — WebShield Browser Extension Blocks Infectious Downloads With Search Marquis

Key Features:

  • Has a real-time protection score of 99% against Mac-specific malware
  • Includes web protection, optimization tools, data breach checker, and more.
  • Works on macOS 10.15 or higher and has apps for Windows, Android, and iOS too.
  • Offers 24/7 live chat, email, and phone support with an extensive knowledge base.

TotalAV’s WebShield is an excellent defense against Search Marquis from getting on to your Mac. It’s a browser extension available on Chrome, Firefox, Edge, and Opera but unfortunately, not Safari. In my tests, it blocked 30+ malicious links leading to infected downloads with Search Marquis and various other spyware, trojans, and rootkits.

Adding to that, TotalAV’s Safe Search feature routes your web queries through its secure search engine. As a result, it gives you 100% online protection against browser hijackers like Search Marquis. However, its real-time score was 99% in my tests as it didn’t detect a couple of rootkits inside zip files. But overall, TotalAV keeps your Mac safe with its:

  • Ad blocker — gets rid of all pop-up ads, preventing Search Marquis from planting cookies into your browser to spy on your online activities.
  • Browser Clean-Up — deletes your browser cookies and history to prevent Search Marquis from tracking your data.
  • Password manager — automatically fills in your online credentials to circumvent the risk of malware recording your keystrokes and stealing sensitive data.

The easiest way to contact TotalAV’s customer support is via live chat. For some reason, I had to log out of my account to locate it on the website. I connected to an agent in under 30 seconds after filling out a quick form and got my queries answered promptly to my satisfaction.

One issue with TotalAV is that its WebShield extension isn’t available on Safari, so you’ll have to use Chrome or Firefox on your Mac to protect yourself online from Search Marquis. This was an issue at the start as I always prefer using Safari, but it didn’t take time to get used to Chrome.

I recommend the Total Security plan, which covers 6 Macs. It includes an unlimited VPN, an ad blocker, a password vault, and all the features of its predecessor subscription. You can try TotalAV before committing as it provides a 30-day money-back guarantee.
