If your Chrome, Firefox or other default browser has been suddenly hijacked by it, then the removal guide below is dedicated to showing you how to uninstall Kyubey.exe Virus and remove all of its changes.

Browser hijackers – what kind of programs are they?

If you face the term browser hijacker for the first time than you probably have no idea whether this is something malicious or not. Fortunately, we have some good news for you. The browser hijackers are non-malicious programs and are not classified as computer viruses or any other type of malware like Trojans, Ransomware, Spyware, etc. These pieces of software are generally used as online advertising tools, but they are often referred to as potentially unwanted. Their activity is related to a rather aggressive marketing approach which involves the modification of the users’ default browser settings and the uncontrollable generation of Pay-Per-Click advertisements, different sponsored messages, promotions and web pages. If you have Kyubey.exe Virus on your PC, then this is the most common disturbance that you are probably facing with this program. What is a bit alarming tough is that the browser hijacker may impose these modifications and ads without your approval and this is what has gained this software the fame of intrusive and annoying one. Many users, who are forced to endure its activity, even decide to fully uninstall it from their system. In fact, this is the only effective way to remove all the unauthorized changes and annoying ads from their screen.

How can this software get inside your machine?

As strange as it may sound, Kyubey.exe Virus or any other browser hijacker usually gets installed on the computer with the active assistance of the users. However, in most of the cases, they are not clearly notified about this installation. This happens thanks to one tricky method known as program bundling. Browser hijackers and other potentially unwanted programs like adware and bloatware commonly get distributed and installed on the peoples’ machines thanks to different software packages (aka bundles), which the users really want to install. These packages usually contain some free program, an attractive application, a game, or some useful piece of software, which promises the users some free functionality, but usually comes along with another program like Kyubey.exe Virus . Such bundles could be found mostly on different platforms for free software distribution, file sharing, torrent sites, spam messages, and emails or free downloads from the web. If users skip reading the EULA in the first place, and don’t pay close attention to options like “Advanced” or “Custom” during the setup itself, they will most probably not be clearly notified about the full list of programs that the given bundle contains and will end up installing the full package by default.

What issues may Kyubey.exe Virus cause?

Apart from messing up your browser, making it unresponsive to your searches and causing frequent browsing redirects and ads interruptions, Kyubey.exe Virus may also be used to track your online activity. This is usually done for marketing purposes, because the “traffic data” that the browser hijacker collects, can be effectively used by the advertisers to learn more about your interests and latest searches. Naturally, this can help them advertise more of their products and services and target them according to the individual users’ search queries. However, this can be disturbing to some extent, and some people may even consider it a privacy invasion, which gives them enough reasons to uninstall the browser hijacker from their system. Not only that, but Kyubey.exe Virus may also affect the normal performance of their computer. Its constant ad-generating activity usually consumes a lot of system resources and can cause some system lags, screen freezing or sudden crashes, which may decrease not only the online experience but the overall performance of the PC.
