Libexec Mac


Libexec is a Mac-compatible piece of software that advertises partnering sites by hijacking user browsers and redirecting their traffic to those sites. To accomplish this task, Libexec installs new elements inside the main browser such as a new homepage, a sponsored toolbar or a search engine.

Libexec on Mac

Libexec can affect almost any popular browser but since Safari, Firefox and Chrome are the most widely used browsers, they are typically the ones that get affected the most. The purpose of the app is to benefit its creators from pay-per-click revenue. It does this by redirecting your search and browsing activity to its partnering websites, whose owners pay a commission for promoting them. The more users are sent to these promoted sites, the fatter is the income earned from the creators of the hijacker. This is the overall behavior of applications of this kind.

Libexec for Mac

Libexec for Mac is online advertising software that actively tries to redirect users to pages it is meant to promote. In order to perform its agenda, Libexec for Mac hijacks the main web browser and installs some sponsored components on it.

For example, the program sets a new search engine that displays paid search results and changes the homepage with a different one that always loads some particular web addresses. As a result of that, the real and the most relevant search results typically get pushed further down the page, and you get prompted to click on sponsored commercials, banner ads, and links.

Also, the homepage placed upon your browser by this intrusive program links to specific websites, so the very moment you start your browser, you automatically get redirected to those sites. The major issue here comes from the fact that some of the sites you may sometimes be rerouted to may contain online dangers like viruses, Trojans, Ransomware and other malware.

What is Libexec?

Libexec is a Mac browser extension that is designed to advertise and redirect users to ad-supported pages. People who have Libexec on their browsers may also be faced with hundreds of hard-to-remove ads, pop-up notifications, and banner messages during their browsing sessions.

The term “Browser Hijacker” is the most common description of such software pieces. Most users almost instantly notice the unwanted application in their browsers thanks to the aggressive pop-up advertisements and page redirects that it starts to generate. But the majority of the victims of hijackers are unable to deal with these ads and seek help to uninstall the software that displays them.
