The Internet is full of useful content and different applications which offer you help and entertainment in many ways. But every computer user knows that in the web space, there are also numerous tricky threats,such as Trojan horse viruses, Spyware, Ransomware and other malicious pieces of software which will do no good to your system if they manage to sneak inside of it. Which group does “Virus” fall into? Well, fortunately, this piece of software is not among the most dangerous computer viruses which you may encounter. In fact, “Virus” is not a virus at all. This application is what is known as a browser hijacker. Now, if you have no clue what exactly a “browser hijacker” means, you should know that this is a term which refers to pieces of software specialized in online advertising. Basically, this software is programmed to promote and aggressively advertise certain web pages, toolbars, search engine tools, homepage domains, browser extensions, ads, pop-ups and banners of different products on the users’ screen during their web browsing sessions. That is why, if becomes part of your system, you may notice that most of your web search queries may get redirected to certain sponsored websites while some new toolbars and browsing components may get integrated with your default browser without your actual approval.

To many users, this is a rather intrusive advertising behavior which is regarded as potentially unwanted. However, the general idea behind this advertising behavior is not to cause any type of harm, system corruption or destruction. The purpose of the hijacker is to promote and to generate revenue for its developers from sponsored page redirects via Pay-Per-Click remuneration models or similar paid ads-generation. Its aggressive promotional approach, though, despite not being as dangerous as the attack of a Ransomware or a Trojan horse for example, may often cause irritation and disturbance to the affected users. This is the main reason why a lot of people want to have applications like uninstalled from their systems. Additionally, in most of the cases, such pieces of software get installed by default (usually via free software bundle installations) and are not really welcomed when they impose their browser changes.

Fortunately, the browser hijacker can be removed without any major risks for the computer and there are two main methods for that. In the Removal Guide below, we have posted some manual instructions which can help you detect and eliminate the unwanted application on your own but you can save some time and effort if you scan your PC with a professional removal tool such as the one on this page and get rid of the hijacker in a few clicks.
