This page aims to help you remove Mshelper. Our removal instructions work for Chrome, Firefox and Safari, as well as every version of MacOS.

Mshelper is a representative of a specific type of software known as browser hijackers which might be able to impose some modifications to your browser once it becomes a part of your system. The way your Chrome, Firefox, Safari, Opera (or any other browser) may get affected by this program may include the installation of some new search engine, the addition of a new toolbar or the replacement of your default homepage/new-tab page. Hijacker applications are also known for triggering redirects to different pages for the purpose of promoting them as well as generating intrusive ads, banners, and pop-ups. Mshelper may launch a redirecting service and modify your search results in such a way that every time you browse for something you will be sent to certain sponsored websites, platforms or offers which may not be relevant to your actual searches. The moment you land on a certain page, your screen may become covered with different blinking boxes, ads, new tabs and commercial messages, which may be difficult to remove no matter how hard you try to close them.

Fortunately, on this page, we may be able to offer you a quick and reliable solution to the browsing disturbance, caused by Mshelper. That’s why, we suggest you read the information that follows and take a look at the Removal Guide below. It contains step-by-step instructions which are specifically developed to help you uninstall this browser hijacker from your system and get your Chrome, Firefox, Safari (or any other browser) back to normal.

Why is Mshelper causing you disturbance?

Despite not being actual computer threats, programs like Mshelper are a common source of disturbance for many online users. The reason is they can take over your browser without your actual approval and may impose certain modifications which may negatively affect the way you normally browse the Internet. Usually, the purpose of such programs is to examine your online behavior and extract some marketing-related data which could be used for targeted advertising.

The moment it becomes part of your system, a piece of software like Mshelper may install a new homepage or a new search engine to the targeted browser, thus replacing the old ones. It may also have access to your browsing history, latest search queries, likes, shares, location, language, bookmarks and similar browsing related information and try to determine what products, services or interests you might have. Based on that, this program may try to display certain ads on your screen or redirect you to sponsored pages which would supposedly be relevant to your preferences.

Step1

WARNING!
To remove parasite, you may have to meddle with system files and registries. Making a mistake and deleting the wrong thing may damage your system.
Avoid this by using SpyHunter - a professional Parasite removal tool.

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.

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,

Fortunately, nothing harmful or fatal would typically result from such activity. Even if you have detected Mshelper on your Macbook, your files and your system should not be under any direct danger because the intentions of this program are likely solely marketing-oriented. Unlike viruses such as Ransomware, Trojans or Spyware, which can cause plenty of problems, the browser hijackers usually do not contain malicious code and normally cannot harm your data or your device. However, the data tracking and ad-generation processes they may initiate may significantly affect with your normal browsing in a negative way and contribute to the slowdown of your system’s performance and browsing speed. This is the main reason why most people prefer to remove such software and uninstall all of its components.

What are the most typical sources of browser hijackers?

Ad-producing software such as browser hijackers, adware, and different ad-supported tools may be found on many web locations. The developers usually bundle them with different freeware programs and distribute them as optional additions to the main program. The usual places where users may download bundles with page-redirecting applications like Mshelper include torrent sites, freeware or shareware platforms, free download links, automatic installation managers and any form of online spam. However, simply downloading a program installer with a hijacker in it is typically not enough for the unwanted software to get inside the system. Most users actually install the hijackers without knowing it when running the installation of the main program from the installer file. In most of the cases, users use the Automatic/Quick installation options without reading the EULA and customizing the setup process. This often lands them the any software that might have been added to the installer including bundled hijackers.

How to remove Mshelper and avoid future contaminations?

Browser hijackers are, fortunately, relatively easy to remove. Unlike threats such as Ransomware, Trojans or other nasty computer viruses, these irritating page-redirects can be uninstalled even by a non-experienced computer user as long as some basic removal instructions are followed. In the Removal Guide below, we have listed the exact removal steps that you’d need to complete with added screenshots so we suggest you use them if you want to get rid of Mshelper.
