Search Marquis program

Search Marquis 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, the Search Marquis 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. 

Questions about

After such actions, the Search Marquis virus starts initiating its bogus 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 redirect activities.

Search Marquis 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. redirect virus 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 such as Search Marquis 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.

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 Search Marquis from Chrome, it might come back with all the unwanted activities.

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 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.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
