is a program that can often be mistaken for a virus. In reality, however, is a browser hijacker that can change the configurations of your web browser and spam your screen with nagging pop-ups.

The Virus will interfere with your browser.

On this page, we’ll give you more details on what this program is capable of, how can it affect your machine and how can you uninstall it effectively. So, if you really want to get rid of its irritating behavior, stay with us and take a look at the removal guide at the end of this post.

As most browser hijackers, can impose changes on your browser, such as replacing the homepage or the default search engine, redirecting your searches to other pages that have nothing to do with your actual interests and displaying hundreds of pop-up ads on every website that you visit. If this particular piece of software has unexpectedly invaded Chrome, Firefox, Edge or another web browser of yours, then the instructions below will show you how to uninstall it and remove all the unwanted changes. Luckily, the removal of is not as hard as the removal of a real virus, such as a Trojan or Ransomware infection, but if you still can’t handle with it, on this page there is also a professional removal tool that can help you.

When you first hear the term “browser hijacker”, you probably don’t know whether this is a bad thing or not. We’ve got some good news for you, though. Browser hijackers are non-malicious programs and are not a threat to your computer. Their features greatly differ from those of malware such as Trojans, Ransomware, Spyware, and so on because such programs are typically used as online advertising tools.


Despite not having harmful features, however, browser hijackers like Margefrick are often considered potentially unwanted. Their activities are linked to an aggressive approach that includes changing the browser settings and generating a stream of unregulated pay-per-click advertisements, various supported messages, promotional links, and page-redirect invites.

Changes like those are not the worst thing that you can expect from this software if you have on your PC. What can been considered a little disturbing is that the browser hijacker will most probably enforce these changes and advertisements without asking for your permission. 

This is the reason why most users prefer to uninstall the browser hijacker entirely from their device and reset their browser preferences. That is also the only effective way to remove the unauthorized changes and distracting messages from your screen.

What problems can cause?

Aside from messing with the settings of your main browser, a piece like may monitor your online activities, keep track of your searches and cause frequent browsing redirects to random websites. This is usually done for marketing reasons because the people who advertise through this program can effectively use the “traffic data” that the browser hijacker gathers to find out more about your interests. This, in turn, can help them target users individually with more relevant ads and offers.

Nonetheless, this activity is somewhat disturbing and some people may find it as a sufficient reason to uninstall the browser hijacker. Besides, can also affect the computer’s normal performance as it may consume a significant portion of system resources and can cause system unresponsiveness, screen freezing or unexpected crashes, which not only reduce the quality of the online experience but also the overall performance of the machine.
