Mighty Browser

Mighty Browser is considered a Browser Hijacker application by most security experts. The presence of Mighty Browser on your browser may cause the generation of pop-up advertisements and disturb your browsing in general.

Mighty Browser

The Mighty Browser Virus will redirect your browser searches.

Like any other program of this type, Mighty Browser has probably taken over your browser (Chrome, Firefox, Safari, etc.) and has replaced your default homepage and search engine with different ones. However, this is not a reason to worry because our removal guide at the bottom of this page will help you solve this problem and uninstall both the new settings that have been imposed and the annoying pop-up ads that have started to appear all over your screen. All you need to do is just read through the paragraphs that follow as they will give you a better understanding of the software you are dealing with and the methods to remove it all by yourself.

Mighty Browser is on Mac

Mighty Browser for Mac is an application for Mac systems that researchers deem unwanted. Mighty Browser for Mac is classified as a browser hijacker due to its ability to introduce different changes to the browser’s settings without direct authorization from the user.

A Browser Hijacker is typically designed to display advertisements of all types (pop-ups, pop-unders, on-screen ads, banners, etc.) during the users’ regular web browsing. Apart from that, it monitors your browsing activity, taking special note of the sites you visit and the search terms you type in search engines. This information is then analyzed to adjust the next wave of ads that you are going to see on your screen. And the purpose of this is to make it more likely for you to click on those ads. That’s exactly what the people behind Mighty Browser want – they want you to click on the displayed ads. Every click earns them money on a pay-per-click basis and they will do their best to get from you as many clicks as they can.

What is Mighty Browser?

Mighty Browser is an unwanted Mac browser extension, which will try to popularize different sites by redirecting your browser to them. Malware apps like Mighty Browser are known as browser hijackers and their changes in the browser and the system might expose you to hacker attacks.

Although the above may sound like a creative form of online advertising, many web users find such behavior invasive and even worrying. To make matters worse, landing on misleading ads that do not respond to the images or promotions they display is also possible (and quite common). And, in the worst of scenarios, you can even end up clicking on a malvertisement infected with a virus such as Ransomware. If you click on a malvertisement, you either download the virus automatically or get redirected to a website where the malware infects you. Of course, we need to say that programs like Mighty Browser, Prodigy Search or Search Pulse are unlikely to deliberately generate malicious ads with the intention to infect you with Ransomware or other viruses, yet it’s still a risk you shouldn’t be ignoring.

The Mightybrowser App

The Mighty Browser app is an undesirable extension for popular macOS browsers that security experts classify as a browser hijacker. The Mighty Browser app will add new elements to your browser that will cause page-redirects to sites the hijacker is supposed to promote.

The unavoidable browser unresponsiveness and sluggishness is yet another undesirable effect that the Browser Hijacker can have on your computer. This inevitably happens to anyone who has had the invasive software on their computer for long enough. So, if you are hesitant about whether it is necessary to remove Mighty Browser from your system or not, consider the fact that you may soon find yourself frustrated by your browser’s incredibly long loading times, as well by sudden browser crashes. The amount of system resources that programs of this type may use while operating might also lead to software failures and application crashes, as well as to general sluggishness of your entire system. This may be yet another reason to follow the instructions in the removal guide below and uninstall the disturbing software.

Uninstall Mighty Browser from Mac


We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading ComboCleaner to see if it can detect parasite files for you.

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.



To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading ComboCleaner
a professional malware removal tool.
