How irritating is this problem? (6 votes, average: 4.33)

This page aims to help you remove Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows. is a application that appears like a simple browser add-on but its abilities to modify the settings of the users’ browsers might create a lot of irritation. A number of users have recently contacted our “How to remove” team with complains that this strange new application has made some changes to their Chrome, Firefox or Explorer browser, which they have not approved. They report the appearance of a new homepage domain, the replacement of their default search engine or the installation of a new toolbar which puts hard-to-remove ads, pop-ups, banners and automatic page-redirects on the screen. Unfortunately, is not the only application which can make such changes to the users’ browsers. An entire software category named as browser hijackers consists of applications with such abilities and, in the next lines, we are going to tell you more about them. In many web forums, these pieces of software are referred to as viruses, but if you stay with us, we will explain to you why they are not as dangerous as, say, a Trojan horse infection or as a Ransomware cryptovirus. We will cover their specifics, their distribution channels and, of course, the safest and the fastest methods to have them uninstalled from the system. Those of you, who have on their system, can find a detailed Removal Guide as well as a professional removal tool, both of which can help you to get rid of the ad-generating application and bring your browser settings back to normal.

The good news is that even if you don’t uninstall the browser hijacker right away, likely no major damage would get inflicted upon the system. and other similar apps do not contain the malicious code of a typical computer virus. A hijacker’s presence on the system, however, might affect the way you surf the web in a very irritating way by forcing you to deal with undesired browser changes, constant pop-up ads and automatic page-redirects. The hijackers may also eat up a fair share of your system resources by launching a “traffic data” collection service in the background of the system which is aimed at analyzing your latest searches and web activities and using that info to display ads that are more in-line with your supposed preferences.

Why do people create browser hijackers and what are those apps used for?

The browser hijackers may seem like quite annoying pieces of software and you might be wondering who creates them and for what reason. As we said above, they have no relation to popular pieces of malware such as Ransomware, Spyware or Trojan horses and, luckily, they are not created by some anonymous cyber criminals. These applications are usually creations of legitimate (or semi-legitimate) software developers, who use them for online advertising purposes. The purpose of the hijackers is to promote different sponsored ads, links, web pages, search engines, toolbars, homepage domains and other products on the users’ screen while the users are browsing. Every time people click on the displayed content or use the promoted tools, pay-per-click revenue is generated for the developers of the given hijacker. There is usually nothing criminal in this method of advertising according to the law. According to some users, however, applications like are sources of browsing irritation and unwanted interruptions and that’s why users seek methods to have them uninstalled.

How may you end up with on your system?

Most of the people don’t pay close attention to the installation wizard when installing new software on their computers and this is how they usually end up with a bunch of potentially unwanted or sometimes even hazardous applications on their PCs. If you also have this habit of not reading the EULA and of using the Automatic installation options instead of the Advanced or the Custom settings, here is a tip we have for you. Do not skip that and carefully explore each customization option, small text or pre-selected checkmarks in the installer because this is how you can spot and leave out applications like before they get installed on your system. Another very important piece of advice we have for you is to use your common sense and avoid downloading and installing new apps, free applications, browser add-ons or other components from shady sources such as questionable torrent sites, fishy-looking software packages from unknown developers, freeware platforms, different free pop-ups, spam messages or email attachments if you want to avoid any potentially unwanted software in the future.
