About MacOSDefender Virus

MacOSDefender Virus refers to a Mac infection that hijacks your browser, which is why it’s classified as a browser hijacker. It’s quite an annoying infection because it will disrupt your browsing by constantly redirecting all your searches to weird search websites showing questionable results. The whole purpose of browser hijackers is to redirect to sponsored sites, whose owners can make revenue from increase traffic. A lot of users put up with a hijacker when they notice its presence on their computers, and they are putting their computers in danger by doing so. Redirects to weird sites are not only annoying but also possibly harmful. You can never know on what kind of sites you will end up, so you could easily be exposed to malware or scams.

In order to be able to redirect you, browser hijackers make changes to your browser. Your homepage and default search engine will be changed without your permission, and you will be unable to undo the changes. These changes to your browser make hijackers very obvious infections. However, plenty of users ignore the signs and carry on without getting rid of the threat. If you notice this hijacker on your computer, you certainly do need to remove MacOSDefender Virus.

Browser hijackers are usually installed by users themselves, albeit unknowingly. They use the bundling method, which is essentially adding unwanted programs to legitimate ones as extra offers. If users do not manually deselect the offers, they will install alongside the program. In the next section of this report, we will explain how you can avoid these unwanted installations, so carry on reading.

How did it install?

Because no one would install browser hijackers knowingly, developers use sly techniques to install their unwanted programs onto users computers. Generally, the bundling method is used which is why paying attention to how you install freeware is important. A lot of freeware comes with added offers, and you need to prevent them from installing. It’s not difficult to do it as long as you know how. The most important thing is that you choose Advanced (Custom) settings during installation. Those settings, unlike Default, will make all added offers visible, and you will be able to deselect them. Once the items become visible, all you need to do is deselect the offers. After you have done that, you can continue installing the freeware without issues.

It’s important that you pay attention to how you install programs as many of them come with other offers. You should also pick your download sources more carefully. If you don’t pay attention to what you install onto your computer and how you do it, don’t be surprised to later find unwanted junk programs installed.

What does MacOSDefender Virus do?

Like we have said before, as soon as this infection installs, you will notice. It will take over your browser, whether you’re using Google Chrome, Mozilla Firefox or Safari. Your browser’s settings will be changed and you will be redirected to a weird site every time you perform a search. These settings modifications will be irreversible while the hijacker is present on your computer because it will just keep reversing all your changes. Until you get rid of it, you will constantly be redirected.

What usually happens is when you try to search something via your browser address bar, as soon as your preferred search engine loads you are redirected to a completely different site. That website will display questionable search results, leading to sites which aim to earn revenue from traffic. Those sites will likely have nothing to do with what you were searching for so there is no reason to click on them. Engaging with sponsored search results can also be dangerous because hijackers can lead you to unsecure websites. The results are not checked before they are displayed to you so something malicious can easily be placed there. You could end up on a site that shows you fraudulent content, like scams. Or you could be redirected to a website that is concealing malware.

Browser hijackers are also known to collect information about users, such as IP address, websites visited, search queries, etc. That information can then be shared with questionable third-parties without your authorization. We highly doubt you want any kind of information about you to collected or shared with anyone, so uninstall MacOSDefender Virus instead of putting up with it.
