What is Search Marquis on Mac?

Search Marquis is a browser hijacker. Forcing you to search through the landing page and search engine, Search Marquis will redirect you to Bing or Yahoo. And on the way, your queries will pass through several advertising networks, making money for those behind the virus.  


That by itself is annoying, but there are other reasons you need to get this malware off your computer. Other symptoms you may see from a Search Marquis infection on your Mac:

  • Unexpected browser add-ons: Search Marquis may install browser extensions without permission. These can further compromise your Mac’s security.
  • Dangerous redirects: This malware may also redirect its victims to dangerous websites, including phishing sites.  
  • More ads than normal: If you find you’re suddenly bombarded with pop-up ads, it could be a sign of a Search Marquis infection.  
  • System slowdown: The presence of Search Marquis can affect the performance of your browser and macOS in general.

In other words, Search Marquis is bad news. And it doesn’t matter whether you use Safari or a third-party browser, like Chrome or Firefox. Search Marquis can affect them all, and it’s something you should fix ASAP.
