24b.eu Virus


24b.eu is a program that is known or its ability to integrate with your browser and spam it with various online ads. Therefore, 24b.eu is commonly referred to as a browser hijacker.


The 24b.eu virus try to gather browsing data from you in order to determine your exact preferences

Browser hijackers are very widespread type of software, and most users have encountered one of these pieces at least once in their lives. But if this has been your first time dealing with a hijacker, then its effects may have been quite unsettling to you. Specifically, the introduction of a new homepage in your Chrome, Firefox, Edge or other popular browser tends to throw users off right off the bat. That is usually followed by noticing that the default search engine is no longer the same either, and the plot thickens.

Then normally after they’ve spent some time browsing the web, users begin to take note of the unusually large numbers of ads that are appearing on pretty much every page they visit. And over time it becomes increasingly difficult to maneuver past the endless popups, banners, in-text links, etc. And the only way you can rid yourself of all this madness is by removing 24b.eu from your system with all of its components. However, this task isn’t exactly made obvious by the browser hijacker itself in that it doesn’t have a designated uninstallation option the way that most regular programs have. Therefore, you will need to take some manual steps, which we’ve described in the removal guide below.

The 24b.eu virus

Browser hijackers like the 24b.eu virus are actually designed specifically to generate numerous online ads within users’ browsers, just as we’ve already mentioned. The purpose of the 24b.eu virus is for the hijacker developers to earn commission based on the number of times users have been exposed to this product or that service. This is possible thanks to remuneration schemes such as Pay Per Click.

 And in order to maximize profits from these practices, programs like 24b.eu and Top Captcha Solver may try to gather browsing data from you in order to determine your exact preferences. So, say you’ve been searching online for a new camera. The hijacker will register this information and adjust its ads to have a bigger focus on camera and related products to ensure that you will actually click on them. And while there is nothing fundamentally wrong with this activity, users may feel that they’re privacy is being violated if they didn’t knowingly consent to it. Furthermore, who’s to say that this information won’t be packaged and sold to some third party as valuable marketing data?

With the above in mind, we should still emphasize the fact that 24b.eu does not aim to harm your machine in any way. Unlike viruses and malware such as Trojans, ransomware, spyware and others, this particular piece of software does not have the capacity to steal files, damage them, log your keystrokes or in any way manipulate your operating system. But as a result of its many page redirects, there is a danger of actually being exposed to viruses. So please be very careful when interacting with any content displayed by 24b.eu .
