This guide provides comprehensive instructions to assist Windows users in uninstalling and removing Chromium viruses and rogue Chromium-based browsers from their computers. By following these steps, you will not only learn how to eliminate the Chromium virus but also restore your browsing experience to its normal, secure state. Please note that some of the methods detailed in this article may require administrator permissions to execute fully. This guide is applicable to both Windows 11 and Windows 10 operating systems, ensuring a broad range of users can benefit from these instructions.
What Is Chromium?¶
Chromium is fundamentally a legitimate open-source browser project, often referred to as the Chromium project. Its core objective is to create safer, faster, and more stable browsing technologies, ultimately delivering a seamless and efficient browsing experience for users. It serves as the foundational framework for the widely recognized Google Chrome browser. However, the similarity in names between Chromium and Chrome has unfortunately been exploited by malware developers. These malicious actors misuse the Chromium name to distribute and install harmful code onto unsuspecting Windows computers, creating confusion and security risks for users.
What Is the Chromium Virus? What does it do?¶
The Chromium virus is a type of malware that can infiltrate your computer system regardless of whether you actively use the Google Chrome browser or not. Numerous Chromium-based browsers with questionable origins can secretly install themselves on your system, thereby compromising its security and functionality. These malicious browsers are designed to engage in a range of harmful activities. They can meticulously track your online behavior, gather personal information without your consent, and potentially steal sensitive data such as passwords and financial details. Furthermore, they are notorious for aggressively displaying intrusive advertisements and pop-ups, significantly disrupting your browsing experience. More seriously, they can facilitate identity theft or cause unwanted browser redirects, leading you to potentially harmful websites.
BeagleBrowser, BrowserAir, BoBrowser, Chedot, eFast, Fusion, MyBrowser, Olcinium, Palikan, Qword, Tortuga, and Torch are just some examples of suspicious Chromium browsers that are known to employ these deceptive and harmful tactics. It’s particularly noteworthy that all these malicious programs are constructed using the same open-source Chromium software, often making them appear deceptively similar to legitimate browsers.
Once a user unknowingly installs one of these malicious browsers, it can redirect them to fake search engine results, convincing replicas of bank login pages, and even websites designed to steal credit card information. Alarmingly, all the data entered on these fake pages is captured and transmitted to a remote server controlled by cybercriminals, who then exploit this stolen information for fraudulent activities.
How Does Chromium Browser Infect the Computer?¶
The primary methods of entry for the Chromium virus into computer systems are often through freeware downloads, acting as bundleware, and via deceptive spam emails. These Potentially Unwanted Programs (PUPs) are designed to infiltrate your computer stealthily. Therefore, it is crucial to maintain vigilance during the installation of any new software. Always carefully review the installation process and ensure that no additional, unwanted third-party software offers are hidden, typically under “Advanced” or “Custom Install” options. In some instances, Chromium viruses can also be installed through malicious browser extensions, further highlighting the need for caution when adding extensions to your browser.
Once installed, a Chromium virus can aggressively take control of various system settings. It can hijack file associations, URL associations, and forcibly set itself as the default web browser. Furthermore, it will often change your browser’s homepage and default search engine without your explicit consent. Adding to the deception, these malicious browsers often closely mimic the appearance of Google Chrome, even using the Chrome logo or a very similar design. This visual similarity makes it easy for unsuspecting users to be targeted and tricked into using the malicious browser, believing it to be a legitimate application.
Signs the Chromium Virus Is on Your Computer¶
Identifying a Chromium virus infection early is crucial for timely removal and minimizing potential damage. Here are some common signs that may indicate your computer is infected:
- Unconsented Search Engine Change: Check if your browser’s default search engine has been altered without your explicit permission. This is a frequent tactic of Chromium viruses.
- Persistent Search Provider Changes: Notice if the search provider unexpectedly changes every time you open a new tab or click within the search bar in your browser. This erratic behavior is a strong indicator of infection.
- Irrelevant Search Results: Evaluate the relevance of your search results. If they are consistently less relevant or filled with advertisements compared to your usual experience, it could be a sign of a compromised browser.
- Unnatural Advertisement and Pop-up Frequency: Observe the number of advertisements and pop-ups you encounter while browsing. An unusually high and intrusive volume of ads is a hallmark of adware and browser hijackers like the Chromium virus.
- Offers of Free Premium Versions: Be wary of browsers that suddenly offer a “Premium” version for free or aggressively push upgrades. This is often a deceptive tactic used by malicious software to gain legitimacy.
These Chromium viruses are also classified as browser hijackers, and they often masquerade as legitimate open-source web browsers to deceive users.
How to Remove Chromium Virus from Windows 11/10¶
If you suspect or confirm that your system is infected with Chromium malware, it is imperative to take immediate action to remove it. The following step-by-step guide will help you effectively eliminate the virus from your Windows 11 or Windows 10 computer.
Removal Steps Overview:
| Step | Action | Description |
|---|---|---|
| 1 | Kill Suspicious Programs | Terminate any running processes related to the Chromium virus using Task Manager. |
| 2 | Uninstall Malicious Programs | Remove suspicious applications from your system through the Control Panel’s “Programs and Features” section. |
| 3 | Remove User Data & Settings | Delete the Chromium user data folder from the local AppData directory. |
| 4 | Check Chrome Extensions | Examine browser extensions for any unknown or malicious additions and remove them. |
Remember, you may require administrator privileges to complete some of these steps successfully.
1] Kill Suspicious Programs¶
The first step in removing the Chromium virus is to terminate any active processes associated with it. Begin by closing all open web browsers on your computer. Next, launch the Task Manager. You can do this by pressing Ctrl + Shift + Esc keys simultaneously, or by right-clicking on the Windows taskbar and selecting “Task Manager.”
Once Task Manager is open, navigate to the “Processes” tab. Look for any processes that are named “chromium.exe” or “chrome.exe.” The Chromium process might display a logo that is similar to the Google Chrome logo but could be distinct, potentially blue in color, or slightly different in design. Carefully examine the list of running processes and identify any that seem suspicious or unfamiliar, especially those with the Chromium or Chrome name. Select each of these suspicious processes one at a time and click the “End task” button located in the bottom right corner of the Task Manager window. This action will forcefully close these processes, preventing them from further interfering with the removal process. It is crucial to ensure that all instances of these processes are terminated before proceeding to the next step.
2] Uninstall Malicious Programs¶
After terminating the running processes, the next crucial step is to uninstall any malicious programs associated with the Chromium virus from your system. To do this, you need to access the “Programs and Features” section of the Control Panel. You can open the Control Panel by typing “Control Panel” in the Windows search bar and selecting the Control Panel app.
Once the Control Panel is open, navigate to “Programs” and then click on “Programs and Features.” This will display a list of all programs currently installed on your computer. Carefully examine this list and look for any programs that have a blue Chromium icon or any other icons that appear suspicious or unfamiliar. Pay close attention to program names that you do not recognize installing or that seem out of place.
Specifically, be on the lookout for known malicious programs that are often associated with Chromium infections. These include programs with names like Power+, APP+, Smash APP+, PDFPoof, BatBitRst, MessengerNow, SearchAd, MyPrintableCoupons, Reading Cursors, ProMediaConverter, PDFOnline-express, See Scenic Elf, Clickware, Easy Speedtest, or WebDiscover. This list is not exhaustive, so remain vigilant for any other unfamiliar programs.
If you identify any suspicious programs in the list, select the program you want to remove and click the “Uninstall” button located at the top of the program list. Follow the on-screen prompts to complete the uninstallation process for each malicious program you identify. It is important to uninstall all suspicious programs to ensure the complete removal of the Chromium virus and associated components.
3] Remove Chromium user data and settings¶
As an added precaution to ensure the complete eradication of the Chromium virus, it is recommended to manually delete the Chromium user data folder. This folder may contain residual files and settings associated with the malicious browser. To access this folder, you will need to navigate to the hidden AppData directory.
Open File Explorer and in the address bar, type C:\Users\%username%\AppData\Local and press Enter. This command will directly take you to the Local folder within the AppData directory for your user account. Note that the AppData folder is typically hidden, so you may need to enable “Hidden items” in the “View” tab of File Explorer to see it.
Within the Local folder, look for a folder named “Chromium.” If you find it, right-click on the “Chromium” folder and select “Delete.” This action will remove the Chromium user data folder and its contents.
It’s important to note that if you are using the legitimate Google Chrome browser, deleting this “Chromium” folder will not harm your Chrome installation. Google Chrome will automatically recreate this folder with genuine user data when you next launch the browser. This step primarily targets the data associated with the malicious Chromium virus, ensuring its settings and potential remnants are removed from your system.
After deleting the Chromium folder, it is also crucial to examine your installed browser add-ons and extensions for any suspicious or malicious entries. Open each of your installed browsers (Chrome, Edge, Firefox, etc.) and navigate to the extensions or add-ons management page. In Google Chrome, you can type chrome://extensions/ in the address bar and press Enter. For other browsers, the process is similar and can usually be found in the browser’s menu under “Extensions” or “Add-ons.”
Carefully review the list of installed extensions. If you find any extensions that you do not recognize, did not intentionally install, or appear suspicious in nature, remove or uninstall them immediately. Malicious extensions can be a source of reinfection or continue to compromise your browsing experience even after removing the main Chromium virus program.
4] Check for Unknown Chrome Extensions¶
While some Chromium viruses manifest as standalone browsers, others operate as browser extensions, making them equally critical to identify and remove. When attempting to eliminate the Chromium virus, it is just as important to check for and remove any unwanted or malicious extensions that might be hijacking your browsing experience.
These malicious extensions might have been installed unintentionally, come bundled with other software, or even deceptively listed in the Chrome Web Store or similar extension marketplaces. To check for and remove suspicious extensions in Google Chrome, follow these steps:
- Open Chrome: Launch the Google Chrome browser.
- Navigate to Extensions: In the Chrome address bar, type
chrome://extensions/and press the Enter key. This will open the Chrome Extensions page, displaying a list of all extensions currently installed in your browser. - Examine the Extensions List: Carefully review the list of installed extensions. Look for any extensions that you do not recognize installing, that have vague or misleading names, or that seem to have excessive permissions.
- Remove Suspicious Extensions: If you identify any suspicious extensions, click the “Remove” button located next to the extension in the list. Chrome will prompt you to confirm the removal. Click “Remove” again to proceed with uninstalling the extension.
- Restart the Browser: After removing any suspicious extensions, it is advisable to restart your browser to ensure the changes are fully applied.
The same process applies to other browsers like Microsoft Edge and Mozilla Firefox. Each browser has its own method for accessing and managing extensions, but the principle of reviewing the list and removing unfamiliar or suspicious items remains the same. Once you have removed any malicious extensions, you may also consider resetting your browser to its default settings to undo any changes made by the virus and ensure a clean browsing environment.
After completing these manual removal steps, it is highly recommended to perform a thorough scan of your computer using reputable antivirus software. Additionally, utilize a specialized tool like AdwCleaner. AdwCleaner is particularly effective at detecting and removing browser hijackers and Potentially Unwanted Programs (PUPs), which are often associated with Chromium virus infections. Running both an antivirus scan and AdwCleaner will provide a comprehensive cleanup and further enhance the security of your system.
Once you have completed the virus removal process, it is good practice to set your desired webpage as your browser’s homepage and change your preferred search engine in your browser settings. This will help restore your preferred browsing configuration and prevent the Chromium virus from reasserting control over these settings.
Finally, consider using CCleaner to clear out any residual junk files and registry entries that may have been left behind by the Chromium virus or the removal process. This can help optimize your system’s performance and ensure a cleaner system environment.
Why is Chromium popping up on my PC?¶
If you observe the Chrome browser repeatedly launching itself even after you have removed it from the Startup programs and closed it from the Task Manager, this behavior is not normal and is a strong indication of a problem, likely a Chromium virus infection. In such cases, it is best to proceed with removing any suspicious applications that are causing this behavior.
Navigate to Control Panel > Programs and Features and carefully examine the list of installed programs. Look for any application that sounds like “Chromium” or has a similar name, or any program that you do not recognize installing. Select the suspicious app and click “Uninstall” to remove it from your system. This should resolve the issue of Chromium persistently popping up on your PC.
Chrome vs. Chromium: What’s the Difference?¶
It is important to understand the distinction between Google Chrome and Chromium. Chrome is a fully-featured web browser developed by Google and widely used by consumers globally. Chromium, on the other hand, is an open-source browser project. Google Chrome is built upon the Chromium project, incorporating the core Chromium engine along with additional proprietary features and functionalities developed by Google.
Chromium is primarily oriented towards developers and serves as a platform for browser development and experimentation. While both share a similar core, Chrome is a more refined and user-friendly browser aimed at general consumers, whereas Chromium is more of a base platform for browser innovation.
Why can’t I remove Chromium from my computer?¶
In some situations, you might not find any program explicitly named “Chromium” in your installed programs list, yet you continue to experience Chromium-related pop-ups or browser hijacking symptoms. In such cases, the Chromium-related components might be integrated as part of another software package or application that you have installed. To address this, you will need to identify and uninstall the entire software package that is causing the issue.
When you observe Chromium running (e.g., when the pop-ups appear), open the Task Manager. Locate the “chromium.exe” process in the “Processes” tab. Right-click on the “chromium.exe” task and select “Open file location.” This will open File Explorer and show you the folder where the Chromium executable file is located. Examine the files and folders in this location to identify the parent program or software package that is running Chromium. Once you have identified the parent program, go back to Control Panel > Programs and Features, find the identified program in the list, and uninstall it. This should remove the Chromium components that were bundled with it.
By following these detailed steps, you should be able to effectively remove the Chromium virus from your Windows 11 or Windows 10 computer and restore a secure and clean browsing experience. Remember to stay vigilant about your online activities and software installations to prevent future infections.
