How to Remove Search Marquis
Search Marquis is a browser hijacker that commonly affects Safari and Chrome users on Mac computers. Whenever you open a new browser window or perform a search, Search Marquis may redirect you to websites that generate advertising revenue for its operators. Search Marquis is also sometimes associated with Search Baron, an older name linked to similar browser-hijacking activity.
Many users notice the problem because their browser’s homepage or search engine has been changed, and they are unable to restore their preferred settings.
Search Marquis may appear to work through a browser extension, but the unwanted extension can be installed alongside potentially unwanted software or malware on the computer. Therefore, removing the browser extension alone may not always be enough. You should scan your Mac for unwanted software and then manually review your browser settings.
Step 1: Run a Full System Scan With Your Antivirus
Important: Avoid connecting your phone, tablet, USB drive, or other external storage to a computer that you suspect may be infected. If malicious software is present, it could potentially spread to connected devices.
Start by running a full system scan with a reputable antivirus or anti-malware program. A full scan can check files, applications, browser-related components, and other areas where unwanted software may be present.
Allow the scan to finish completely. Do not stop it simply because the antivirus detects one suspicious file. There may be additional unwanted components on the system.
The duration of a full scan depends on the amount of data stored on your computer and the security software being used. Once the scan finishes, review the detected items and allow your security software to quarantine or remove confirmed threats.
If ransomware is one of your concerns, you can also learn more about how antivirus software can prevent ransomware and what security features to look for when choosing protection.
Step 2: Delete Any Infected or Unwanted Files
If your antivirus has identified and quarantined suspicious files, follow the software’s recommended removal process.
Advanced users may review quarantined items to check for false positives, but you should not restore a file unless you are confident that it is safe.
After removing confirmed threats, restart your Mac. Once the computer has restarted, run another scan if your security software recommends it.
Removing malicious files from your computer is important, but Search Marquis may also have changed your browser extensions, homepage, search engine, or notification permissions. Therefore, you should continue with the browser cleanup steps below.
Step 3: Remove Search Marquis From Your Browser
Once you have scanned your Mac and removed suspicious software, check your browser carefully.
For Safari Users
Follow these steps:
- Open Safari.
- Open Safari > Settings.
- Select the Extensions section.
- Review all installed extensions.
- Remove extensions that you do not recognize or no longer need.
- Check your homepage and search settings.
- Restore your preferred homepage and search engine.
Be especially careful with extensions that were installed without your knowledge. You should not keep an extension simply because it claims to improve browsing speed, search results, or security.
You can also review Safari’s website permissions and remove notification permissions from websites that you do not trust.
For Chrome Users
To check Chrome:
- Open Chrome.
- Select the three-dot menu.
- Open Extensions > Manage Extensions.
- Remove extensions you do not recognize.
- Open Settings.
- Go to Search Engine.
- Select a trusted search engine.
- Open On Startup and remove any unfamiliar pages.
- Review site notifications and remove suspicious permissions.
If Search Marquis continues to appear after changing these settings, another application on your Mac may be responsible. In that case, run another malware scan and check recently installed applications.
Clear Browser Cache and Website Data
After removing suspicious extensions and restoring your settings, clear your browser’s cache and website data.
In Chrome, open Settings > Privacy and Security and select the option to clear browsing data.
In Safari, use its privacy settings to remove stored website data and cached information.
Clearing this information can help remove unwanted website data, although it will not remove malware that is installed elsewhere on your computer.
Step 4: Keep Your Devices From Getting Reinfected With Malware
Removing Search Marquis is only part of the solution. You should also take steps to prevent similar browser hijackers from returning.
Malware developers regularly change their techniques, so keeping your software updated and practicing safe browsing habits is important.
Keep Your Software, OS, and Drivers Up to Date
Keep macOS, your browser, applications, and other software updated. Updates often include security fixes that address vulnerabilities.
On Mac, open System Settings > General > Software Update and check for available updates.
You should also update applications through their official update mechanisms or trusted app stores.
Avoid continuing to use outdated software simply because an older version still works. Unsupported applications may contain vulnerabilities that no longer receive security fixes.
Don’t Download Suspicious Files
If you do not know where a file came from, do not download or open it.
Malware often disguises itself as a useful application, browser extension, software update, document, or media file. Suspicious emails and websites may also use urgent messages to pressure you into downloading something immediately.
Before installing an application, check whether it comes from a legitimate developer and use an official source whenever possible.
A reputable antivirus program can provide an additional layer of protection by scanning downloads and warning you about potentially dangerous files.
Use a Secure Web Browser
Your browser plays an important role in online security because it handles websites, downloads, passwords, cookies, and extensions.
If you are considering switching browsers or want to improve your browsing security, read this guide to the most secure web browsers to use.
Regardless of which browser you use, keep it updated and avoid installing unnecessary extensions.
Secure Your Wireless Network and IoT Devices
Your home network is another important part of your overall security.
Use a strong Wi-Fi password and make sure your router is running current firmware. You should also change default administrator credentials and avoid leaving unnecessary network features enabled.
Internet-connected devices such as smart cameras, TVs, speakers, and other IoT products should also be protected with strong, unique passwords.
If your Wi-Fi network is open or uses weak security settings, unauthorized users may be able to connect to it.
What Kind of Virus Is Search Marquis?
Search Marquis is generally described as a browser hijacker or potentially unwanted program, rather than a traditional computer virus.
It may change browser settings, redirect searches, modify the homepage, display unwanted advertisements, and collect certain browsing-related information.
The exact behavior can vary depending on the software bundled with the browser hijacker.
Search Marquis may also be accompanied by other unwanted applications. This is why simply changing the search engine back to Google may not solve the underlying problem.
A reputable security program can help identify unwanted components that are difficult to find manually.
Download a Secure Antivirus Program
There are many antivirus and anti-malware products available for Mac users. However, you should choose security software carefully.
Look for a solution that offers:
- Real-time malware protection
- Web protection
- Phishing protection
- Regular security updates
- Malware scanning
- Protection against potentially unwanted applications
- Mac compatibility
Do not download antivirus software from a suspicious pop-up claiming that your Mac has been infected. Fake security warnings can themselves be part of a scam.
Instead, download security software directly from the developer’s official website or another trusted source.
How Do I Get Rid of Search Marquis on Chrome and Safari?
You can remove Search Marquis by following a combination of system and browser cleanup steps:
- Run a full malware or antivirus scan.
- Quarantine or remove confirmed malicious files.
- Restart your Mac.
- Check Safari or Chrome extensions.
- Remove unfamiliar extensions.
- Restore your preferred search engine.
- Check your homepage and startup settings.
- Remove suspicious website notification permissions.
- Clear browser cache and website data.
- Keep macOS and your browser updated.
If the problem continues after completing these steps, check your recently installed applications and login items for software that may be responsible for changing your browser settings.
Can Search Marquis Come Back?
Yes. Search Marquis or another browser hijacker can return if the original source of the unwanted software has not been removed.
For example, downloading software from unofficial websites, installing unknown browser extensions, or accepting bundled software during an installation can introduce unwanted programs.
To reduce the risk of reinfection:
- Download applications from trusted sources.
- Avoid pirated or cracked software.
- Do not install unknown browser extensions.
- Keep macOS updated.
- Keep your browser updated.
- Use reputable security software.
- Be cautious with unexpected email attachments.
- Do not click suspicious advertisements or fake security warnings.
Conclusion
Search Marquis is a browser hijacker that can interfere with Safari and Chrome by changing search settings, redirecting searches, modifying the homepage, and displaying unwanted content.
The most effective approach is to deal with both sides of the problem: remove unwanted software from your Mac and restore your browser settings.
Start with a full malware scan, remove confirmed threats, review browser extensions, restore your search engine and homepage, and clear suspicious browser data.
You should also keep macOS and your browser updated and avoid downloading software from untrusted sources. With these precautions, you can reduce the chances of Search Marquis and similar browser hijackers returning to your Mac.
