How to get rid of Search Marquis Mac

Search Marquis

Search Marquis is a commonly-encountered browser hijacker for Mac devices that enters the browser unnoticed and introduces unwelcome changes to it. Search Marquis is known for adding a search engine of the same name to the browser and flooding the user’s screen with aggressive ads.

Search Marquis is not a virus in the sense that it doesn’t replicate inside the system and doesn’t try to damage it. However, the effects that this unwanted software has on the browser could lead to a variety of online privacy and security problems. On the surface, all Search Marquis does is it tampers with the browser’s settings, spams the user with ads, and triggers redirects to different promoted websites. However, what remains hidden is the ability of this browser hijacker to secretly collect data from your browser and distribute it to third-parties. Who those third-parties are is a mystery – such information is never disclosed by Search Marquis. Obviously, in most cases, the data from your browser would get distributed to other advertisers who seek to target you with personalized ads. However, there’s no guarantee that hackers and crooks won’t also get their hands on information extracted from your browser. For that reason, it is never advisable to keep unwanted browser-hijacking software such as Search Marquis on your Mac – not only could it automatically send your browser to obscure locations filled with ads but also it may end up collecting and selling data from your browser to anonymous third-parties with unknown intentions.

      • Hi Cal Benton,
        yes we recommend ComboCleaner and its a trusted program. You can download it and use its trial version to remove the malware from your Mac.

    • Hey Brandon, I followed this article (remove search marquis virus mac) up until the point when it told me to go to the action monitor and take a sample of any “suspicious processes.” I am able to take the samples, but I don’t know what to do with them. How do I analyze these samples to know whether or not I should delete them?

      The search marquis has gotten quite out of hand at this point. I am automatically redirected to it every time I open a new tab, or even if I click the back button to return to my google search results. I have removed it from all settings that I can find, yet still the problem persists. Thanks for your help.

      • Hi Dan, I believe you sample any of the suspicious processes so you can find the paths to the files related to these processes, you can use the online virus scanner on the page to confirm or deny your suspicions.

    • Hi Petkov, where is this online virus scanner , please? If it is combocleaner, this function is no longer free and I am unaware of it it’ll remove completely if I pay.
