browser hijacker (Free Guide) browser hijacker Removal Guide

What is browser hijacker?

Chromnius is a potentially unwanted application that sets itself as the default browser to promote sponsored content and show ads is a web address of the web browser that may bring more ads than usual

If you have spotted that any links you click are opened on a different browser than you're used to, and the homepage is set to the URL, you have a potentially unwanted application installed on your system. Namely, a browser that is presented as an alternative to Google Chrome, Mozilla Firefox, MS Edge, or another used one at the time.

The application operates like any other browser hijacker, except it's using its own browser to do the job. You could have downloaded it via its official website or completely by accident whenever you installed freeware or shareware from third-party sources (software bundling). Likewise, you may have come across ads online that could have convinced you.

Once on the system, the hijacker would search the homepage and new tab to Chromnius New Tab, which would also alter the search engine and its results. You are then would be forced to search via the hijacker's search engine, which would use as a provider. These results would not be accurate and would be filled with sponsored links at the top. Likewise, ads are more likely to encounter while using this browser.

Type Browser hijacker, potentially unwanted program
Distribution Bundled software, third-party websites, official app site
Symptoms An alternative browser Chromnius is set to be default whenever using the internet; the homepage and the new tab are set to be of the app; an altered homepage and search box produce ad-filled results
Risks Data tracking from various third parties, exposure to malicious ads, redirects to phishing sites
Removal You can remove the unwanted program manually, but you should scan your system with security software to ensure it isn't infested with additional viruses
Other tips After removing all potentially unwanted applications, we recommend you employ the FortectIntego utility to clean your web browsers and repair any damaged system files

How Chromnius spreads and how to avoid it

As mentioned, there are three ways one could download and install this potentially unwanted application:

  • Software bundling[1]
  • Official website
  • Advertisements

If you have intentionally installed the app as an alternative to Chrome or another browser, you should consider going back to your original one. With so many choices available, it is not surprising that some of the apps may turn out to be potentially unwanted applications, and users may install them without realizing this fact.

The most likely cause of having installed is due to software bundling – the technique is extremely common when it comes to potentially unwanted application distribution. Typically, third-party websites that distribute freeware are known for this, so if you frequent sites like that, you should be much more careful when dealing with them.

One of the main points to pay attention to when dealing with bundles is the tricks used there. Most commonly, users are tricked by pre-ticked checkboxes, fine print text, misplaced buttons, and similar. Therefore, you should never rush the installation process of new programs from these sites and use Advanced/Custom mode instead of Recommended/Quick whenever it's possible.

It is worth noting that you should stay away from websites that distribute pirated software, cracks, and similar. These websites can be operated by cybercriminals to spread malware to as many users as possible. For example, you may get infected with Aamv ransomware[2] if you execute files downloaded from torrent sites.

How to effectively remove the potentially unwanted app

If you have Chromnius installed on your device and you are not happy with the changes it made due to ads and other issues, we recommend you remove it from your system. Since it's a browser, it had to be installed on the system level, so you can remove it by checking the installed program section on Windows or Mac systems.

Before you proceed with these instructions, we recommend you make a thorough check with SpyHunter 5Combo Cleaner or Malwarebytes security software to ensure that there are no other potentially unwanted applications or malware running in the background without your knowledge. Having a reputable security app on your device would also prevent future malware attacks.

Once you have finished removal, we would also recommend cleaning browser caches to ensure no data tracking taking place.

How to prevent from getting browser hijacker

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. 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 the server or network manager that needs to monitor connections and activities. 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.


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.
