A few things to know about browser hijackers…

Browser hijackers like Moosjs.cn are often referred to as potentially unwanted programs that create a significant browsing-related disturbance to some people. The reason for that is, these programs fill their screen with nagging sponsored advertisements and place some unwanted extensions and toolbars or impose some unauthorized changes in their default browser, which are a bit tricky to remove. Very often, the users’ searches may get redirected to different websites and sponsored pages, and they may end up on unknown web locations that may eventually hide some viruses or malware from the rank of Ransomware and Trojans. Moreover, browser hijackers may collect some data about the users’ browsing habits, the browsing history, bookmarks and most visited pages and use it to match their sponsored ads to it. By doing this, programs like Moosjs.cn may heavily obstruct the users’ normal browsing experience, and make them end up being frustrated from surfing the web. That is the main reason why so many people want to remove such programs and uninstall all of the imposed changes and components from their computers.

However, despite being so annoying, browser hijackers differentiate from viruses and malicious threats, such as Trojans, Ransomware, Spyware and others. Their purpose is not to compromise your machine or do harm to your system and data, but to generate profit from the clicks on the displayed ads. Programs like Moosjs.cn are specialized in that, and they are involved in the Pay-Per-Click scheme, which turns all the clicks that users give when they are exposed to the ads and the sponsored pages that the hijacker displays into profit. The owners of the hijacker earn some good revenue from that, and this is the main reason why they load so many annoying promotional messages on your screen. Basically, ad-generating software of this type is just one of the ways that the online advertising industry uses to promote their products and services directly on the users’ screen. There is nothing illegal about that, but sometimes the huge amount of redirects and promotional messages may cause so much disturbance, that the affected users will eagerly look for ways to remove the hijacker and clean their browser from the ads.

How can you catch a browser hijacker?

There are several commonly employed techniques for distributing ad-generating components like Moosjs.cn. Spam emails, ads, sketchy websites full of free software, online installation managers, shareware platforms, and torrents are some of the most common places where browser hijackers could be found. How they get installed on your computer, however, has a lot to do with your habits of installing new software on your system. Usually, programs like Moosjs.cn come bundled inside the installer of a free program or an application that you want to install, but you may not see them if you run the installer with the “Standard/Quick” installation option. To see them, and prevent them, you need to click on another option in the setup, which is called “Advanced” or in some setups – “Custom”. This is where all the programs in the bundle will be visible and you will be able to prevent the installation of the programs you may not want. Skipping this will land a browser hijacker or other potentially unwanted piece of software, the uninstallation of which may require a removal guide like the one below.
