This page aims to help you remove the Moosjs.cn “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.
The article you are going to read has been written with the sole purpose of explaining how a program called Moosjs.cn normally acts, and what the proper methods of removing it are. To begin with, you have to know that this product is based on browser hijackers, which means that it can only infect and affect your browsers (Chrome/ Firefox/Explorer) and it is fully capable of:
- displaying numerous advertisements like colorful boxes, banners and pop-ups;
- authorizing your browsers to redirect you to often unfamiliar web pages, that you have never had the intention of visiting;
- making your browsers substitute the usual homepages and search engines you are already used to with entirely new ones, which could be unknown to you.
Browser Hijacker basics
In general, browser hijackers count as ad-generating programs, which are NOT hazardous at all. This means that there is a big difference between Moosjs.cn, for instance, and the most widely spread viruses such as Ransomware and Trojan horse versions. To prove this statement we are going to mention the basic differences between these two types of software.
- Always remember that the hijackers we have come across so far only possess the aforementioned features, plus some more slightly disturbing ones. Such an annoying possible consequence that may result from the activities of Moosjs.cn is the potential slowdown of your machine. Sometimes the redirecting and ad-producing processes might consume a lot of RAM and CPU, thus making your device a little slower. Nevertheless, such a possibility entirely depends on the characteristics of your computer. Another slightly unpleasant effect of most of the developed hijackers is that once they have infected your browsers, they could receive access to their history records. Consequently, you can expect to see only ads containing familiar goods or advertising services you have recently been researching. Also, the same could happen with the redirecting process. The pages you are being sent to could have to do with your common search requests.
- The viruses we have mentioned above, on the other hand, are capable of doing many more dangerous things to your PC – Trojans could steal important private details (such as banking info or account credentials); they can record your key strokes, turn on your camera and watch you remotely. The Ransomware-based viruses could access all your disks and drives, determine which files you use most and lock them up so that you won’t be able to access them.
- Based on the above arguments, we can conclude that Moosjs.cn is not a malicious program and at least, you don’t have to worry about that.
One more quite shady characteristic of the Moosjs.cn “Virus” and its sibling programs is the way they normally get spread. Among the potential sources we can name the illegal software and torrent-distributing websites, some torrents, spam in any form, and contagious pop-ups. Nonetheless, the source to be blamed for the biggest number of infections ever is called program bundling. To bundle means to gather all kinds of software (games/apps/programs/ Adware and hijackers) together and spread them in such mixtures. Normally, such combos are completely free for the user and you may get very excited, because of the prospect to use free software, which seems new and interesting to you. Here comes the basic mistake most of the victim users make that gets them infected with the Moosjs.cn “Virus”. In case you have decided to really download and use such bundled software, you need to calm down and act in a sensible way. Briefly speaking, you need to install the bundle in the most harmless way, which means that you shouldn’t use the following installer options:
- Recommended/ Quick/ Default/ Automatic – as they cannot give you the entire power to change and customize the installation process. Generally, they could only install the entire bundle and you may end up infected as a result of that.
Instead, the wizard options which will work best in your interest are called:
- Custom/ Advanced – if you select one of them, you will have the power to change the number of the programs you want installed on your PC, as well as their specific features that you desire.
To be completely precise, this piece of advice is very general and could save you from very serious threats such as malware contamination. Learn to perform such a controlled installation process and you will completely minimize the chances of catching a browser hijacker (and all other kinds of irritating programs).
