How to remove Search Marquis from your Mac

7 min read

Search Marquis is a nasty but curable malware. We recommend you minimize interaction with the infected browser and start the cleaning process as soon as possible. This will help you protect your private information. Let's now jump into the instructions on how to get rid of Search Marquis. 

What is the Marquis virus?

Technically, Search Marquis is not a virus because a virus can replicate itself (just like its natural analog) and gradually infect different files. So, what is Search Marquis? It is a type of malware called a browser hijacker. It "embeds" itself in your browser and changes its settings. It works like this.

After infection, a fake search engine searchmarquis(.)com appears in your browser instead of the homepage (don’t follow the web address). In response to your search query, it redirects you to several intermediate URLs (you may not notice this) and then lands on a Bing search page. It's usually filled with sponsored content that has little to do with your query but just bombards you with ads. 

Purpose of it? To make money from your traffic. Usually, the revenue is generated through those hidden redirects. The advertiser's website receives allegedly unique visits and apparently pays Search Marquis a commission. Another possible source of income is your data. It may be sold to shady marketing agencies, who then bombard you with intrusive ads.

What are the symptoms of Search Marquise?

It's impossible not to notice this hijacker on your computer. You'll probably smell something fishy when you'll encounter two main symptoms of Search Marquise:

  • Your homepage has changed to searchmarquis(.)com.
  • When you try to visit a website, you are redirected to searchmarquis(.)com.

In addition, the websites you visit may suddenly become packed with ads and pop-ups. Your browser may become unusually slow and laggy, and your computer's memory may suddenly become full.

We recommend that you remove Search Marquise as soon as you notice it because it may compromise your privacy.

The easiest way to remove Search Marquis on your Mac

The fastest way to remove Search Marquis is to use apps with an antivirus component. They check all the nooks and crannies on your Mac where malware could have slipped in and clean them up.

We recommend trying CleanMyMac X, a comprehensive tool for cleaning and optimizing your Mac. It's powered by the Moonlock Engine anti-malware technology, which can fight malware, adware, ransomware, and all other macOS-specific "wares". It takes no more than a few minutes to remove any harmful programs.

Here's how to remove Search Marquis with CleanMyMac X:

  1. Download and open CleanMyMac X.
  2. Navigate to the Malware tab.
  3. Click Scan.
  4. When the app detects Search Marquis, click Remove.

In addition, run a smart scan to get rid of system junk that accumulates on 100% of actively used Macs (and being infected could have contributed to the clutter).

At this point, you may need another app that has nothing to do with malware removal. We're talking about iStat Menus, and its job is to monitor all Mac systems. What is its role in the whole story?

The thing is, not all malware behaves as blatantly as Search Marquise. Some are stealthy, but they can't hide their impact on CPU, GPU, network usage, browser load, and more. iStat Menus monitors all these processes and notifies you when something goes wrong.

For example, if your CPU is suddenly overloaded when you only have a few browser tabs and one app open, there's a good chance something malicious is draining your resources. With iStat Menus, you're on the safe side, and you'll be alerted the moment something goes wrong.

Remove suspicious login items

You may have apps on your Mac that launch as soon as you log in - so-called Login items. They usually appear when you install a new app and click Yes to the question "Launch when log in? But malicious tools can sneak in without you knowing.

  1. Go to Apple menu > System Settings.
  2. Click General > Login items.
  3. Use the minus icon to delete any login item containing Search Marquise in the title or other you consider suspicious.
