How to remove Search Marquis from Mac

7 min read

As Mac users, most of us have gotten used to the idea that “Macs have no viruses” and definitely relaxed our vigilance in that area. While it’s true that most Windows viruses won’t be able to attack Macs the same way due to their sandboxed architecture, plenty of other malware finds its way into Macs all the time, often being helped by unsuspecting users themselves. 

Since most people believe that Macs can’t get infected, they willingly download all kinds of files and software on their Macs. Software installation, in particular, requires your admin approval. So hackers often bundle up legitimate software with malicious extensions, which get admin access to spread further right from the user. 

One of the most persistent viruses of that type in recent times has been Search Marquis, a redirect virus that hijacks your browser and redirects your homepage to its own.

Let’s see what is Search Marquis, how dangerous it is, and how to get rid of Search Marquis on Mac. 

What is Search Marquis?

Search Marquis is a redirect virus that makes all of your web traffic go through (don’t visit that website), a landing page with a search field that would redirect any search to Bing or Yahoo.

Why would Search Marquis hijack your traffic only to send you to Bing or Yahoo? When you search for anything using Search Marquis’s website, your query will first travel through a bunch of intermediary domain names, most of them advertising networks (e.g.,,, which would pay Search Marquis for such hits. That’s pretty much the reason — generating money through your clicks. 

Unlike some other horror-story viruses that block your computer or encrypt your data, Search Marquis is not destructive but still plenty annoying and taxing for your system.

Symptoms of Search Marquis virus 

Most of the time, you’d have no idea that your Mac was infected with Search Marquis — that is until you open your browser. 

When you see your browser redirecting to Search Marquis, and then Bing or Yahoo, you know your Mac has been infected. It’s likely that you either unknowingly installed Search Maquis browser extensions or downloaded other software that had Search Marquis attached to it. 

You might also notice your Mac runs painfully slow and you might encounter odd pop-ups and new tabs you didn’t intend to open. 

In the future, try to only download software from well-recognized stores and sources. In the meantime, here’s how to block Search Marquis from Mac right now.
