This page aims to help you remove Bookness Virus. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.
Browser hijackers aren’t really fun to deal with, but every now and then they seem to find their way into our computers. One of the latest variants of this type is called Bookness Virus and it will be the topic of our article today. Just like other programs of this type, Bookness Virus will change your browser’s homepage and will set its own search engine as the default one. On top of that, you are likely to experience frequent page redirects during the time that this hijacker is on your PC. And if you’re wondering what kind of browser it is that a browser hijacker might be more prone to invade – pretty much all of the most popular ones can become infected. So it doesn’t matter, whether you’re using Chrome, Firefox, Edge, Opera or a different one. You will also not be able to restore the settings of your browser to the state they were in prior to the infection. That you will only be able to do as soon as you remove the hijacker from your PC. And that is where we come in – we are offering you a detailed removal guide, which will help you locate and uninstall Bookness Virus from your system. But before you head over to the guide, do read through the article here first.
The purpose of Bookness Virus and how risky it can be for you
Browser hijackers basically exist for the single purpose of generating and displaying numerous online ads. Such are, for example, popups, banners, box messages and in-text links. We’re sure you’ve already seen plenty of them on your screen and they have by now also probably driven you nuts. Well, the producers and vendors of the various products and services that are being promoted by those ads actually pay the browser hijacker developers for that. Only that happens in a fairly interesting way. The developers earn revenue based on the number of clicks their ads collect from users just like yourself. This happens in accordance with remuneration models like the infamous Pay Per Click scheme or PPC.
However, this very remuneration system is what dictates the aggression with which the ads are basically shoved in the users’ faces. But aside from the blatant aggression, there’s also something else that the developers highly rely on in order to maximize their profit. They usually program their hijackers like Bookness Virus to be able to track the browsing patterns of the users. For example, they can monitor the kind of websites you visit, as well as those that you bookmark or favorite. In addition, they also pay attention to the things you search for online, as well as even the things you post and like on social media. All of this information can give the hijacker the necessary insight into your interests and will allow it to determine which of its ads will be more attractive to you. after some time you can actually begin to notice yourself, how the ads you keep seeing oddly relate to your recent online activity.
Now, this may seem pretty disturbing to you and while it certainly is a violation of your privacy, it’s nothing illegal, nor is it genuinely dangerous to you. Browser hijackers like Bookness Virus are not viruses, but they can have the ability of unwillingly exposing you to them. This could happen as a result of the changes that the hijacker may introduce to your Registry, which may, in turn, weaken your system and make it more susceptible to outside attacks. Alternatively, the many ads that you constantly keep seeing on your screen can equally expose you to various threats, such as Trojans and ransomware. Various cybercriminals and hackers often rely on things called malvertisements for the distribution of their malicious programs and viruses. Malvertisements are online ads that are injected with malicious scripts and once you click one of them, you can end up getting infected immediately. They are all the more dangerous, because they look no different than your regular online ad. For this reason we like to advise our readers to simply abstain from interacting with any form of popups, banners and similar ads. there’s no telling, which of them may be malicious and it’s simply not worth risking your security to find out.
|Danger Level||Medium (nowhere near threats like Ransomware, but still a security risk)|
|Symptoms||A chamge in browser’s settings, such as a new homepage and new search engine.|
|Distribution Method||Progrma bundles distributed on various freeware and shareware platforms, and similar.|
Some threats of this type reinstall themselves repeatedly if you don't delete their core files. We recommend downloading SpyHunter to scan for malicious programs. This may save you hours and cut down your time to about 15 minutes.
