Discovery Engine- How Did I Get It and What Does It Do?
The Discovery Engine application may be downloaded and installed via the so-called bundling method.
What should you know about bundled software installers? Bundling is a form of aggressive advertising deployed by many programs and software download websites, both legitimate and bogus. While many of the bundled programs are generally legitimate, in cyber security this is one of the main ways via which potentially unwanted programs, like browser hijackers or adware such as Discovery Engine, are spread across users’ computers.
Once on your computer system, Discovery Engine may show up that it is a legit internet browser or an app promoted as a useful utility. Nevertheless, the purpose of Discovery Engine is changing the settings of your internet browsers, whether they are Firefox, Chrome, Opera, Safari, etc.
Then, Discovery Engine could trigger different ads on your Mac, including:
- Internet browser redirect.
- Ad-supported search engine result.
- Pop-up ads.
- Banners.
- Highlighted text on the sites you see.
The advertisements themselves could not be harmful; however, some of them may redirect you to different hazardous websites, including fraud sites or harmful sites that can land malware on your Mac
Furthermore, the undesirable application may start providing ads based upon your online behavior. These ads might be actually frustrating and intrusive as their main objective is to trick you into clicking them. Be cautious that these sites might be contaminated and configured to cause the activation process of various other undesired programs.
