The following article explains everything you need to know about Discovery Engine and other browser-hijacker-type programs. We’ll not only explain the origin of the annoyance you’re dealing with but will also give you detailed instructions on how to remove it from your system along with all the pop-up ads, page-redirect links, banners, and new features it has probably introduced to your browser.

The first thing you’ve probably noticed when you opened your browser (be it Safari,Chrome, Firefox, or another one) is a change in the homepage or the default search engine. Another, even more obvious sign of having a browser hijacker such as Discovery Engine on your computer are the numerous ads that are constantly present on your screen, regardless of the websites you visit. These can range from random pop-ups and banners to colorful box message in different shapes and sizes. But the most irritating thing of all is that no matter how hard you try to remove them, your attempts would likely only results in more pop-ups appearing or your screen. The same applies for the imposed homepage or the newly set search engine – you can’t uninstall them no matter how many times you try to reset the browser’s settings.

Discovery Engine for Mac is an intrusive browser add-on that triggers unwanted browser changes and obstructive page-redirects during each online session. Although Discovery Engine for Mac isn’t an inherently malicious app, its uncontrolled activities might lead to issues with your Mac’s security.

Well, the truth is browser hijackers are used as marketing tools that help online advertisers to promote their products and services online. The marketers use programs like Discovery Engine to place specific sponsored advertisements on the user’s screen with the hopes to get more clicks on said ads. This is because they earn money based on the number of clicks the ads get from the users. This explains the strange positioning of the numerous advertisements and their intrusiveness, which leaves the users without an option to ignore them.

What is Discovery Engine?

Discovery Engine is a browser hijacker that installs in popular browsers on macOS computers. Junkware apps like Discovery Engine are known for opening new browser windows and tabs without permission with the aim to boost the traffic to certain websites.

If you have had Discovery Engine on your system for long enough, you may also notice that a lot of the displayed ads mysteriously match your recent search queries. This is because such programs, apart from spamming you with random ads, typically have the ability to track your browsing activity and use this information to determine what kind of products and services you are most interested in. The idea is to display ads that are matching your latest searches so that you eventually click on them. This activity is a common online marketing tactic but is often considered as potentially unwanted since there are many people who are worried about the fact that a program can track their web searches and frequently visited sites.

The DiscoveryEngine App

The DiscoveryEnggine app is a form of unwanted browser extension programmed to generate ads in macOS browsers. To complete its task, the DiscoveryEngine app will install helper elements in the infected browser such as a new search engine or new toolbar buttons.

Despite the rather questionable online advertising tactics it uses, a program like Discovery Engine cannot really do any harm to you or to your machine. This software lacks the destructive abilities of malicious infections such as Trojans or Ransomware. However, you should be very careful about the ads the browser hijacker displays, as they may sometimes land you a real virus, including the above-mentioned Ransomware or Trojan Horses. The thing is, malicious ads exist and they can sneak in the stream of regular ads very easily. With this in mind, clicking on a misleading ad or banner is very possible, and you can never know where it may redirect you to. Therefore, a good solution is to avoid all ads and uninstall any software that spams you with random commercials uncontrollably.
