What is is a misleading extension that creates issues on various machines, including macOS devices

Search Marquis programThe hijacker modifies the main engine of the web browser app

Searchmarquis is a browser hijacking virus that sets its own engine as default to promote sponsored websites and generate income from advertising. It belongs to the group or Potentially Unwanted Applications (PUA) targeting Macs[1] exceptionally with the help of doubtful third-party Mac app bundles. Upon installation, it tends to change the main search engine, homepage, new tab settings to

Later on, a customized engine may add additional browser-based programs, extensions, or system applications to control more of the online traffic and browsing functions or the device itself. Such infections can be categorized as potentially unwanted programs because of the silent infiltration and intrusive symptoms raging from redirects and pop-up ad display to installations of additional undesired programs.

After such actions, the hijacker starts initiating its deceptive activities – redirecting to advertising services, and collecting income via pay-per-click schemes. The browser hijacker plants cookies into the browser to spy on the user's online sessions and produces attractive adverts. Research showed that Searchbaron is closely related to this browser hijacker, so you shouldn't be surprised if after a few clicks the screen reroutes you to this domain.

There is very little to no value in most browser hijacking applications, so you should clean the machine thoroughly in order to stop the excessive tracking and redirects. The PUP is related to and domains. Users note that these are the ones that searches and browsing sessions get redirected through.

All the additional content that is delivered to your screen when browsing sessions get affected by the PUP triggers pop-ups, banners, and other commercial material. Also, online search attempts via this engine deliver results filled with in-text links and other content without creating any alleged value and usefulness.

This app belongs to the potentially unwanted program category because it uses stealth techniques to enter the targeted computer system. This usually refers to bundling measures or security-lacking websites. Once the app is on the machine, be prepared to face bogus activities.

These are the main symptoms of this shady search engine:

  • default homepage, new tab, and search engine gets changed to Search Marquis;
  • all search attempts redirects to other sites show results filled with links and other types of commercial material;
  • toolbars, extensions, add-ons, and other content gets installed without your permission or knowledge;
  • advertisements appear on sites where they aren't supposed to be.

The app might present itself as a useful product, however, do not fall for believing in these claims as you might easily get tricked by the developers. They might add “handy features” to the browser hijacker such as fast access to popular networks. However, the true feature of this program is to plant tracking components and gather non-personal data:

We collect non-identifiable aggregated information (“Non-Personal Information”) about your device and your use of Services. Non-Personal Information which is collected includes: technical information transmitted by your device, your aggregated use of the Service, statistics, type of browser and default search preference, operating system type, language and the time and date you access and use the Service, website which you lead you to the Offer, approximate geographical location, Internet Service Provider (ISP), Internet Protocol address (IP), etc.

While this type of gathered information might seem meaningless from the first view, note that browser hijackers generate fake offers and deals that rely on this data and attract a big number of users. Do not click on any ads that come from this hijacker as you might be redirected to somewhere dangerous.

Here we end up with another problem related to the hijacker – redirecting.[2] Frequent redirects are mostly caused to take the visitor to an affiliate web source and convince him to buy some useless products. However, sometimes you might be forced to land on a potentially infectious website.

Search Marquis removal is a necessary step to take if you are heading towards the ultimate computer and browsing safety. You can easily find all bogus products that might have been planted on the computer system with the help of proper anti-malware tool. Of course, feel free to choose any other type of program.

System optimizers or PC repair tools like FortectIntego can help you further clean the machine by fixing virus damage and repair corrupted or differently affected files.

Remove virus from Chrome for good

While most browser hijackers are relatively harmless and easy to eliminate, others apply various stealth and persistence techniques that would prevent easy removal. For example, some PUPs might establish the “Managed by your organization” status on the web browser, which will repel any attempts to uninstall the suspicious extension. In such a case, the best way to get rid of these settings is by resetting the web browser altogether.

Additionally, some settings might be stored within Google's database – extensions, apps, autofill, themes, history, and other settings. In some cases, these might hold unwanted components within your Google account. As a result, even if you remove the PUP from Chrome, it might come back with all the unwanted activities.

Therefore, you can reset Chrome sync easily by accessing a specific page on your web browser – Data from Chrome sync. Simply scroll down to the bottom of the page and click on “Reset Sync.” This way you can properly eliminate Search Marquis from the device.

Shady download websites are actively involved in affiliate marketing

Tech experts from[3] state that browser hijackers and other potentially unwanted programs are likely to infiltrate the targeted machine/device through sources that lack the required protection. These locations are known to be various P2P networks such as Torrents.

Additionally, bogus products are very likely to enter the computer via free software packages. Programs that are shared for free for downloading/installing purposes do not include any recommended security. This is why you always have to opt for the Custom/Advanced installation mode.

Besides, having a reputable antivirus program running on your machine will do half of the security job for you. However, you cannot leave everything for the anti-malware as you are the one who is responsible for your own, your programs', and your machine's/device's safety level.

How to prevent from getting browser hijacker

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
