Note that Chromium browser virus is not related to Chrome and Chromium open-source web project. The latter project[3] is entirely legitimate and doesn’t contain any malicious codes. It is open to anyone who wants to create a customized browser, however, just like any other open-source tool, it gets exploited by malevolent people. If you noticed that your browser acts suspicious, check if it isn’t replaced by a bogus version.

Chromium browser virus
Chromium browser virus is a set of applications that can disturb users with excessive advertisement campaigns, and sometimes even direct them to malware-laden or phishing sites.

Typically, users infected with Chromium virus do not notice anything suspicious because the aim of this shady add-on is to persuade them into thinking they are using the genuine version of the browser. However, suspicious redirects[4] and also annoying pop-up ads shortly reveal that something is wrong with the browser, and users might start looking for suspicious programs or browser extensions on the system.

Sadly, there might be none because the virus disguises its processes well. On the other hand, if you check Task Manager processes, you might notice Chromium.exe process. It stands out by consuming large amounts of CPU memory energy resources. To recover after such a virus and fix system changes initiated by it, use Reimage Reimage Cleaner . You can detect and remove Chromium browser virus from a Mac or Windows operating system with the help of SpyHunter 5Combo Cleaner or Malwarebytes

Chromium virus is a term used to describe suspicious, ad-supported, and also malicious web browsers built using Chromium browser source code. In this picture, you can see an example of such web browser and also an example of fake Chrome Update ad.

Main features of Chromium browser virus 

It is dangerous to keep Chromium virus on the system as there are numerous unauthorized activities initiated by this unauthorized malware, including the following ones:

  • tracking the user’s online activity and collecting NPII and PII;
  • redirecting traffic to sponsored sites;
  • filling websites with the sponsored content;
  • pushing fake updates, push notifications, etc.

Once you are tricked into installing the malicious Chromium-based website, it starts its activity from tracking your actions online the entire time you use it. Therefore, the virus observes what websites you visit, what ads you click, and entries you type. Such information might be collected by third-parties should reach someone you cannot trust. Besides, the collected data is typically used to deliver targeted advertisements, and it also means that it can be used to serve deceptive, but luring content for you.

Therefore, expect to see a lot of catchy ads offering hard-to-believe deals as well as ads suggesting you check out adult-only websites or install software updates you did not even know you “need.”

Be careful if you notice that your browser causes redirects to a particular website every time you launch it. Chromium browser virus might attempt to force you to use a particular search engine just to provide you with a bunch of sponsored search results next to organic ones and then trick you into clicking them. 

Furthermore, during its stay, the hijacker may bother you with constant redirects and similar issues. Due to this phenomenon, the browser may direct you to potentially insecure domains[5] or ask to disclose personal information[6]. Avoid staying too long on these websites, and, instead, focus on the Chromium virus removal. 

A detailed list of malicious browsers

BeagleBrowser virus

BeagleBrowser by Lollipop Network, S.L. is a potentially unwanted program (PUP) that takes over the victim’s computer and starts displaying annoying ads to the victim. Although the developers of the software present it as a browsing tool that helps to “create a clean and safe environment for surfing the web,” it proved to be yet another adware-type web browser that seeks to push paid content to its users daily. There is no wonder why so many users try to remove BeagleBrowser shortly after installing it.

BrowserAir virus

Although it claims to be “free, fast and lightweight” web browser, it functions as a typical adware program that causes URL redirections triggers pop-up ads and deteriorates browsing experience. It is highly advisable to remove BrowserAir virus to improve computer’s performance and secure browsing sessions.

BrowserAir is one of many Chromium virus variants


Chedot virus is a highly deceptive web browser that loads page on startup. This page quickly redirects the victim to a modified version of Google. Such redirection is required to convince the victim that he/she is using the real version of Chrome (since the majority of Chrome users use Google as homepage). However, further activities initiated by this browser hijackers aren’t pleasant and should not be ignored.

The suspicious browser is ad-supported, which means that it will test all possible ways of serving sponsored offers and pushing ads to the victim. The user of Chedot Browser might run into ads in search results, see them in pop-up or pop-under ads, banners, or full-screen ads. These ads hardly ever provide useful offers and simply annoy the victim, so it is better to eliminate Chedot.

Yandex browser

Yandex browser is primarily used by Russian-speaking users and is basically an alternative to Google in the region. While the application is known to include several security features to protects its users (such as DNS encryption, file scanning, DNS spoofing protection, etc.), it also replaces Cortana with “Alice” and spawns pop-ups even when the browser is off.

The browser is also supported by often features from the company, such as Yandex toolbar, redirect, etc. Without a doubt, users will not get accurate search results while the app tampered with various settings, and will end up on sponsored sites instead. Therefore, better remove Yandex browser and use the original Chrome application instead.

Ways to install fake web browsers

You can accidentally enable Chromium virus hijack if you tend to install new programs with “Standard” or “Default” mode on. It is of high importance to modify installation settings in order to prevent infiltration of potentially unwanted programs.

All you need to do is to find and configure installation settings the right way – choose “Custom” or “Advanced” installation settings and look for suspicious checkboxes with shady statements next to them.

If you can find statements that grant your permission to install unknown programs, browser toolbars and similar pieces of software, do not proceed with the installation until you configure them the right way. Deselect the ticks from these checkboxes and then continue. Finally, we must warn you that Chromium browser virus can be distributed via “Urgent Chrome Update” ads.

However, some fake versions of web browsers can reach the victim’s computer when installed alongside illegal software. We strongly recommend you to stay away from free licensed version packs you can download from torrent sites or other suspicious web sources. Placing them on your system can allow hazardous files to get in as well.

How to remove Chromium virus from Windows and MacOS

Remove Chromium virus windows 10 as soon as you notice that your Chrome browser behaves in a suspicious way. You may want to check the Chrome version via browser settings. However, remember that criminals can make the bogus browser display a fake Chrome version just to convince victims that they are using a legitimate version of the Internet browser, so you shouldn’t trust the information provided in Chrome’s “About” section.

To find out the truth and complete Chromium removal successfully, we advise you to perform a system check using anti-malware programs. It is likely that Norwegian users[7] might be more targeted by this PUP. Thus, they should be more cautious.
