The Chromstera browser

The Chromstera Browser is basically a sneaky piece of software that takes over your web browser without your consent. It does this by installing its own version of the Chromium browser, which is an open-source project that Google Chrome is based on. Once the Chromstera Browser is on your system, it makes a few changes to your browser settings. For instance, it sets its own page called “Chromstera New Tab” as your browser’s default homepage and new tab page. So, when you open your browser, you see this page instead of your usual homepage. In addition to that, it hijacks your browser’s search functionality. When you perform a search, it redirects your queries through “Chromstera Search,” which, in turn, redirects you to search results from

What is Chromstera?

Chromstera is a type of software that quietly enters your computer and messes with your web browser. What it does is a bit tricky – it changes your browser so that it takes you to websites you didn’t plan to visit. It could even change your homepage, which is the page your browser opens to when you start it. Sometimes, it might also change your search engine, which is what you use to find things on the internet. The tricky part about Chromstera is that its main goal is to make money for the people who made it by showing you pay-per-click ads. Even though this is not as harmful as a Trojan Horse attack, it can still mess up your internet use and make your online time less enjoyable.

Is Chromstera safe?

If you are wondering is Chromstera safe, you should know that while not as malicious as some other cyber threats, this program should not be underestimated in terms of potential risks. It falls into the category of browser hijackers, which means it can make alterations to your browser settings without your consent. These changes may affect your browsing experience, privacy, and even expose you to potentially hazardous online content. Therefore, to protect against Chromstera safety issues, it’s essential to regularly update your browser, use robust security tools or antivirus software, exercise caution when downloading and installing extensions or plugins, and promptly address any unusual occurrences in your browser are all prudent practices.


The frustration that arises when your browser suddenly redirects you to unfamiliar websites, often promoted by browser hijackers like Chromestera, cannot be overstated. These redirects primarily serve the purpose of generating revenue through pay-per-click models and are often marketed as a means to enhance user engagement with tailored content. However, in reality, these automatic redirects, especially those to Chromestera, can significantly disrupt your browsing experience and pose security risks. Therefore, if you’ve been dealing with these disruptive activities, our strong recommendation is to eliminate the browser hijacker responsible for the redirects. By doing so, you can regain control over your browser and safeguard yourself from potential risks associated with these unwanted redirections.

Chromstera Virus

Although they serve different purposes, the unwanted alterations in browser settings, redirection to unfamiliar websites, and the bombardment of ads by a browser hijacker can often be wrongly associated with a computer virus. Hence, it’s not unusual for users to refer to Chromstera as “the Chromstera virus.” In reality, both types of software can indeed disrupt your online experience, causing unexpected changes and slowing down your computer’s performance. However, their intentions are distinct: a virus aims to damage files and compromise system integrity, while the Chromstera virus, categorized as a browser hijacker like Nighridadered, primarily impacts users’ online activities to generate financial gains without directly harming your computer’s files or system.

Chromstera Pop-ups

The sudden invasion of numerous Chromstera pop-ups on your screen can undoubtedly raise alarm bells. While these pop-ups aren’t inherently harmful, they do pose inadvertent risks by potentially leading users to misleading or harmful content. Clicking on such content can redirect users to questionable or compromised websites, where various security threats may lurk in the shadows. Moreover, these Chromstera pop-ups might trick users into sharing sensitive information, which could later be exploited for targeted advertising campaigns and offers that entice them to install more potentially unwanted software on their system. In essence, while these pop-ups may seem innocuous at first glance, they have the potential to set off a chain of risky events, making their removal a wise choice for a safer online experience.

Chromstera on Chrome

When Chromstera on Chrome takes control of your homepage or default search engine without your permission, it’s time for immediate intervention. The first step is to meticulously inspect recently installed software and browser extensions, as they might be the culprits behind these unwanted changes. Additionally, it’s essential to proactively remove any unfamiliar applications and recently added extensions that don’t align with your regular web surfing habits. After completing these steps, you can venture into your browser settings to manually reset your homepage and search engine preferences, ensuring you reinstate the ones you trust and commonly use. By following these measures, you significantly improve your chances of effectively addressing Chromstera on Chrome and regaining control of your hijacked web browser.

Step1 Uninstall the Chromstera app and kill its processes

The first thing you must try to do is look for any sketchy installs on your computer and uninstall anything you think may come from Chromstera. After that, you’ll also need to get rid of any processes that may be related to the unwanted app by searching for them in the Task Manager.

Note that sometimes an app, especially a rogue one, may ask you to install something else or keep some of its data (such as settings files) on your PC – never agree to that when trying to delete a potentially rogue software. You need to make sure that everything is removed from your PC to get rid of the malware. Also, if you aren’t allowed to go through with the uninstallation, proceed with the guide, and try again after you’ve completed everything else.

  • Uninstalling the rogue app
  • Killing any rogue processes

Type Apps & Features in the Start Menu, open the first result, sort the list of apps by date, and look for suspicious recently installed entries.

Click on anything you think could be linked to Chromstera, then select uninstall, and follow the prompts to delete the app.

This can enable the malware to stay on the computer or automatically reinstall itself after you’ve seemingly deleted it. Therefore, you need to check the following elements by going to the Start Menu, searching for specific system elements that may have been affected, and pressing Enter to open them and see if anything has been changed there without your approval. Then you must undo any unwanted changes made to these settings in the way shown below:

    • DNS
    • Hosts
    • Startup
    • Task
    • Services
