There is a cybercriminal gang on the loose whose activity is shaping up to be a huge concern for the entire Mac community. Although these crooks don’t ruin systems or spread mayhem through greedy crypto-mining behind the victim’s backs, the malicious code they have been creating is hugely obnoxious and extraordinarily hard to remove from plagued Mac machines. The focus of all fishy campaigns under scrutiny is on the web surfing side of computer use. By depositing sneaky apps and plugins onto macOS systems without admins’ consent, the malefactors make browsers act up by rerouting the traffic to sites like searchmarquis.com. What is Search Marquis anyway? It is a manifestation of the virus that gives one’s Internet navigation set-up a malicious overhaul to promote its own landing page.

The Search Marquis virus slithers its way into a Mac by dint of a tricky software packaging scheme referred to as bundling. This technique co-promotes several applications under the guise of one that’s benign and typically free of charge. While legit per se, the mechanism provides attackers with an opportunity to push their harmful programs without notifying the would-be victim. Unless the default setup mode is unchecked and the custom option is selected on the installation client, the malware will rush into the Mac alongside an item that the user is knowingly installing. As a result, the pest gets all the privileges it needs, and the prey is clueless about ever granting these permissions. From that moment on, the Search Marquis infection starts dominating all things web browsing on the target computer without allowing the administrator to revert to their normal configuration in a commonplace way.

As previously stated, this virus zeroes in on web browsers it detects on the compromised Mac. It supports Safari, Chrome, and Firefox – given the prevalence of these solutions, the impact is going to make itself felt in nearly every attack scenario. The rogue helper object incorporated into the victim’s preferred browser instantly tweaks the homepage, search, and new tab page settings to its own advantage. It replaces these values with searchmarquis.com so that the plagued user visits the unwanted page over and over. The offending entity tends to additionally tamper with the DNS server settings for extra persistence. This interference leads to the pseudo search engine being constantly resolved instead of the desired one. To tighten the grip further, the culprit creates a random-named configuration profile under System Preferences that holds sway over the targeted browser settings.

On the face of it, searchmarquis.com seems to be a primitive lookup instrument with a search box and a few links leading to the EULA, Privacy Policy, and the Contact Us page. No matter what keywords are entered in it, the sketchy service will return Bing.com. The route of the navigation, though, also includes a couple of URLs that the victim can only see for a fraction of a second. These transitional items denote advertisement networks where every such inconspicuous hit will count as a unique visit, thereby generating profit for the operators of this hoax. As this malicious campaign evolves, new in-between and destination pages are being added to the wicked mix. A couple of examples are searchnewworld.com and mybrowser-search.com. Both return custom search results powered by a legitimate service, so the hoax keeps heading in basically the same direction, combining clearly harmful activity with benign elements. The shady logic is invariable: the adware hijacks a browser, reroutes it to a worthless provider with no proprietary search algorithms under its hood, and then the traffic reaches a Bing hosted search page. So much for the pranks of the Search Marquis virus. What about the fix? The only way to address the issue is to spot and delete all elements of the perpetrating app. Read the follow-up sections to find out how it’s done.

Search Marquis virus manual removal for Mac

The steps listed below will walk you through the removal of this malicious application. Be sure to follow the instructions in the specified order.

1. Expand the Go menu in your Mac’s Finder bar and select Utilities as shown below.
2. Locate the Activity Monitor icon on the Utilities screen and double-click on it.
3. In the Activity Monitor app, look for a process that appears suspicious. To narrow down your search, focus on unfamiliar resource-intensive entries on the list. Keep in mind that its name isn’t necessarily related to the way the threat is manifesting itself, so you’ll need to trust your own judgement. If you pinpoint the culprit, select it and click on the Stop icon in the upper left-hand corner of the screen.
4. When a follow-up dialog pops up asking if you are sure you want to quit the troublemaking process, select the Force Quit option.
   
5. Click on the Go menu icon in the Finder again and select Go to Folder. You can as well use the Command-Shift-G keyboard shortcut.
   
6. Type /Library/LaunchAgents in the folder search dialog and click on the Go button.
   
7. Examine the contents of the LaunchAgents folder for dubious-looking items. Be advised that the names of files spawned by malware may give no clear clues that they are malicious, so you should look for recently added entities that appear to deviate from the norm.

   As an illustration, here are several examples of LaunchAgents related to mainstream Mac infections: com.pcv.hlpramc.plist, com.updater.mcy.plist, com.avickUpd.plist, and com.msp.agent.plist. If you spot files that don’t belong on the list, go ahead and drag them to the Trash.

8. Use the Go to Folder lookup feature again to navigate to the folder named ~/Library/Application Support (note the tilde symbol prepended to the path).
   
9. When the Application Support directory is opened, identify recently generated suspicious folders in it and send them to the Trash. A quick tip is to look for items whose names have nothing to do with Apple products or apps you knowingly installed. A few examples of known-malicious folder names are UtilityParze, ProgressSite, and IdeaShared.
10. Enter ~/Library/LaunchAgents string (don’t forget to include the tilde character) in the Go to Folder search area.
    
11. The system will display LaunchAgents residing in the current user’s Home directory. Look for dodgy items related to Search Marquis redirect virus (see logic highlighted in subsections above) and drag the suspects to the Trash.
12. Type /Library/LaunchDaemons in the Go to Folder search field.
    
13. In the LaunchDaemons path, try to pinpoint the files the malware is using for persistence. Several examples of such items cropped by Mac infections are com.pplauncher.plist, com.startup.plist, and com.ExpertModuleSearchDaemon.plist. Delete the sketchy files immediately.
    
14. Click on the Go menu icon in your Mac’s Finder and select Applications on the list.
    
15. Find the entry for an app that clearly doesn’t belong there and move it to the Trash. If this action requires your admin password for confirmation, go ahead and enter it.
16. Expand the Apple menu and select System Preferences.
17. Proceed to Users & Groups and click on the Login Items tab. The system will display the list of items launched when the computer is starting up. Locate the potentially unwanted app there and click on the “-” (minus) button.
18. Now select Profiles under System Preferences. Look for a malicious item in the left-hand sidebar. Several examples of configuration profiles created by Mac adware include TechSignalSearch, MainSearchPlatform, AdminPrefs, and Chrome Settings. Select the offending entity and click on the minus sign at the bottom to eliminate it.
    If your Mac has been infiltrated by adware, the infection will most likely continue to hold sway over your default web browser even after you remove the underlying application along with its components sprinkled around the system.

FAQ

Search Marquis is an element of a broad-sweeping adware fraud targeting Mac computers. Hosted as searchmarquis.com, it is disguised as a garden-variety web search provider but turns out to lack the essential feature that should be inherent to the type of service it tries to impersonate. Specifically, it doesn’t return search results of its own. Instead, the page responds to every request by redirecting the user to bing.com.

This is the behavior exhibited on a healthy computer, where none of the above takes place unless you deliberately visit the sketchy site and do some experimenting. However, things get more complicated if the so-called Bing redirect virus infects a Mac. In this case, Safari, Google Chrome, and Mozilla Firefox will be automatically forwarded to searchmarquis.com without any such intent on your end. This is because a malicious app that has previously slithered into the system and took over the web surfing preferences.

The purpose of this nefarious interference is to hijack and redistribute the victim’s Internet traffic. Although Bing plays a role of the final-stage landing page in this scheme, it has nothing to do with the cybercriminals’ shenanigans who chose as a means to outsource the missing search function of Search Marquis.

First things first, this won’t happen unless you configure Safari this way or your Mac is hit by a browser hijacker that imposes unwanted search preferences without permission. If the former scenario isn’t the case, then the whys and wherefores are entirely in the malware domain. The malicious code that sets this plot in motion is referred to as the Bing redirect virus.

Technically, it’s a potentially unwanted application (PUA) that kicked in behind the scenes by modifying the default settings on Safari. The pest usually makes the rounds via tricky software bundles such as spoofed Flash Player update packages peddled through popup ads on hacked websites. If the predicament is underway on a Mac, the only way to address is to identify and remove the underlying app. Fixing the browser settings comes next on your to-do list.

Search Marquis removal is a two-pronged process. First, you need to uninstall the troublemaking application that has skewed the web browser settings and added a malicious configuration profile that maintains a system-wide impact to hamper all cleaning efforts. To pinpoint the infection, examine the Activity Monitor, Applications, LaunchAgents, LaunchDaemons, Login Items, and Profiles on your Mac. Look for entries that deviate from the norm and send them to the Trash. To get a better idea of how to perform this tidying, follow the steps listed in the tutorial above.

If a suspicious one shows up there, disable and uninstall it right away. The infection might not leave such conspicuous breadcrumbs behind, though. If so, the right move is to reset the browser to its default condition – note that in Safari the procedure is a bit more complicated than clicking on one “magic” button. Again, use the browser-related instructions above to take care of the issue.
