Moosjs.cn virus is a potential threat to your web browser

Moosjs.cn virus is a suspicious website that tends to appear on users computers out of nowhere. However, computer infections to do not magically show up on the devices. Most of the time, users did something wrong. In this case, they installed a new program incorrectly[1] and let browser hijacker[2] get inside the system. This cyber parasite travels with various programs as an additional component and many people did not notice when they agreed to install it too. Once Moosjs.cn browser hijacker finds its way to the computer, it suddenly modifies web browsers’ settings and sets its domain as the homepage and default search engine. Then, it changes Registry, various shortcuts and appends the argument http://moosjs.cn to them. When users notice the hijack, they always try to reset browser’s settings; however, previously mentioned modifications prevents them from saving these changes. However, ignoring the appearance of the browser hijacker is not recommended as well. It might initiate many unpleasant activities and disturb browsing the Internet, for instance, you might receive lots of pop-ups and ads, experience sudden redirects, etc. Besides, if you decide to use this suspicious search engine, you might discover the world of commercial content and dangerous websites. We want to encourage you to initiate Moosjs.cn removal as soon as it hijacks your beloved web browser.

The main page of the browser hijacker is full of various links to social media websites, gaming, and shopping sites, etc. Quick access to the favorite social networks might be useful for the users who are too lazy to make their own bookmarks. However, we recommend staying away from these links. After the click, you might be redirected to the shady third-party website and only then to the preferred one. Moosjs.cn redirect tendencies are quite frustrating. Users might end up on potentially dangerous websites[3], phishing sites[4] or other suspicious domains where they might be asked to reveal personal details, suggested to install bogus applications, and so on. People might also end up on the questionable Internet site if they use this suspicious search engine. Moosjs.cn search engine delivers modified results and might replace relevant links with sponsored ones. Not only might they be irrelevant but also potentially dangerous. That’s why we highly recommend eliminating browser hijacker immediately. The best way to remove Moosjs.cn is to scan your computer with Reimage or other trustworthy anti-malware program.

When did hijack happen?

The developers of the potentially unwanted programs (PUP) use questionable software marketing method called “bundling[5].” It allows hiding the PUP under “Quick” or “Standard” installation mode, and if users trust this setup, they agree to install add additional programs. Therefore, Moosjs.cn hijack has probably occurred when you installed one of the recent programs. Next time you should be more careful with software installation. Opt for “Advanced” or “Custom” installation mode and do not rush. Check each installation step carefully and make sure you did not leave any pre-selected application or statement claiming your agreement to make Moosjs.cn your default homepage. If you skip this step and leave some questionable programs selected, you might have to deal with lots of computer-related problems. We believe that correctly installing software takes less time than virus elimination.
