If you’ve recently noticed some troubling changes that have taken place inside your web browser, then stay with us to learn about their most likely source. Whether you are using Chrome, Edge, Firefox, Safari, or another popular web browser, you’ve probably detected a new homepage or some unfamiliar search engine. You’ve probably also experienced some strange redirects to websites filled with aggressive pop-ups, banners, box messages, and colorful ads. Fortunately, these are not symptoms of an infection with some mysterious virus or malware like a Ransomware or a Trojan. The source of these browser modifications is a browser hijacker called “Your computer is infected with a dangerous virus”. In the next lines, we will give you more information about the nature of this software and we will provide you with a removal guide to help you remove the unwanted program and uninstall its changes from any browser that might have been affected.

What is a browser hijacker?

The browser hijackers are programs designed to integrate with popular web browsers in order to promote certain websites, products, and services. In other words, the browser hijackers advertise specific items on the users’ screen during their web browsing sessions. In order to do that, these programs typically install some helper components (such as a new homepage, a sponsored search engine, a custom toolbar, etc.) that “hijack” the browser’s activity and automatically redirect the users’ searches to the pages that need promoting. Since you are on this page, you’ve probably already noticed how invasive and strategically positioned the commercials on your screen are. This is done to ensure that you eventually click on as many ads as possible and land on the pre-defined pages.

But that’s not the only tactic, programs like “Your computer is infected with a dangerous virus” and Humisnee employ to advertise more effectively. Such pieces of software may often keep track of your web browsing history, your search queries and the pages you frequently visit in order to match its ads with your interests. Based on the collected information, the hijacker tries to “guess” what kind of ads could potentially draw your attention and then it fills your screen with them.

Some people may find this activity as helpful as they may land on an ad that is promoting the exact product or service they have been looking for. Others, however, may land on ads promoting some low-quality products or questionable offers which may trick them into downloading virus-infected content.

This is the reason why, in general, many people don’t trust browser hijackers and seek ways to quickly uninstall them from their computers. As a matter of fact, your device is unlikely to get harmed by a program like “Your computer is infected with a dangerous virus” because, apart from spamming you with advertisements, this software can’t hack into your web camera or microphone like a Trojan infection or encrypt your data like a Ransomware virus. However, if you just don’t want to see pay-per-click adverts every single time you open your web browser, we’ve prepared a step-by-step removal guide below to help you remove the unwanted program.
