Libexec

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.

The Libexec app

The Libexec app is a browser hijacker that can establish control over any Mac browser and force it to redirect users on sponsored web pages. The Libexec app does not have features that can harm a computer but users prefer to remove it in order to regain control over their browsing app.

Besides, many people fear that if they let the browser hijacker redirect them to random web locations, they may bump into security threats like viruses, Trojans or Ransomware-infected pages. That’s why they take advantage of removal guides like the one below and uninstall pieces like Libexec from their Mac computers.

Step1

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.

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

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.

The next step is to safely launch Safari again. Press and hold the Shift key while relaunching Safari. This will prevent Safari’s previously opened pages from loading again. Once Safari is opened up, you can release the Shift key.

First, Force Quit Safari again.

Now if you are using a Wi-Fi connection turn it off by selecting Wi-Fi off in you Mac’s Menu. If you are using a cable internet (Ethernet connection), disconnect the Ethernet cable.

Step4

Re-Launch Safari but don’t forget to press and hold the Shift button while doing it, so no previous pages can be opened up. Now, Click on Preferences in the Safari menu,

and then again on the Extensions tab,

Step5

The threat has likely infected all of your browsers. The instructions below need to be applied for all browsers you are using.

Again select Preferences in the Safari Menu, but this time click on the Privacy tab,
Privacy in Safari

Now click on Remove All Website Data, confirm with Remove Now. Keep in mind that after you do this all stored website data will be deleted. You will need to sign-in again for all websites that require any form of authentication.

Still in the Preferences menu, hit the General tab
