Search Marquis – How to Remove This Browser Hijacker (Mac Guide 2025)

What is Search Marquis?

Search Marquis is a persistent macOS browser hijacker that redirects your browser traffic through several unwanted domains—usually searchmarquis.comsearchbaron.comBing.
It changes your default search engine, installs configuration profiles, and forces unwanted ads and redirects.

This threat is part of a well-known adware ecosystem that targets macOS versions including Ventura, Sonoma, and early 2025 releases.

Why Search Marquis is Dangerous!

Although it looks like a simple search engine, Search Marchise is categorized as a browser hijacker and PUP (Potentially Unwanted Program).

Search Marquis is more than an annoying redirect. It can:

  • Track your searches and visited websites
  • Inject ads into Google results
  • Modify your browser settings and lock them
  • Install malicious configuration profiles that reapply the hijack
  • Redirect you through advertising networks
  • Degrade Mac performance and stability

Although it’s often bundled with seemingly harmless apps, the hijacker creates a persistent loop that makes manual removal frustrating if you miss a single component.

How Search Marquis Infects macOS

Search Marquis spreads mainly through:

  • Fake Flash Player installers (common AdLoad vector)
  • Torrent sites and cracked software installers
  • Bundled installers on file-sharing websites
  • Malicious advertising networks (malvertising)
  • Fake system optimization tools

Important:
Search Marquis is a macOS-only threat.
No verified Windows or Linux variants exist.

Quick Fix (Recommended)

Run a trusted anti-malware tool that scans for browser hijackers and removes malicious profiles, LaunchAgents, and rogue extensions including Search Marquis.

Quick Steps:

Remove Search Marquis manually

Follow these steps in order to completely remove Search Marquis from your macOS.

Step

Remove Malicious Configuration Profiles

Search Marquis almost always installs a rogue config profile that forces the redirect.

  1. Open System Settings
  2. Go to Privacy & Security
  3. Scroll down to Profiles (only appears if something is installed)
  4. Look for suspicious profiles such as:
    • AdminPrefs (known real Search Marquis profile)
    • Anything locking homepage/search settings
  5. Select → Remove Profile

If you see AdminPrefs, you found the primary persistence mechanism.

Step

Remove Suspicious Applications​

    • Search Marquis
    • Unknown “Manager” or “Data” apps
    • Fake cleaners or boosters
  • 3. Move them to Trash → Empty Trash.

Step

Check LaunchAgents & LaunchDaemons​

Search Marquis components often use generic random names but belong to the broader macOS AdLoad family.
However, NO confirmed unique plist names exist specifically for Search Marquis.

You may safely check:

  • User LaunchAgents
    • ~/Library/LaunchAgents/
  • System LaunchAgents
    • /Library/LaunchAgents/
  • System LaunchDaemons
    • /Library/LaunchDaemons/

Chrome

  • Settings → Reset Settings → Restore Settings to Default
