Musmentportal is a rogue browser add-on specifically designed to take control of the browser it gets attached to, replace its homepage and/or search engine address, and flood it with obscure web advertisements. File-bundles and misleading site notifications are typical Musmentportal distribution methods.

Of all the annoying, nagging, irritating and obstructive forms of software you could unwillingly get on your computer, browser hijackers seem to be some of the most frustrating and also some of the most widespread ones. A browser hijacker is an application that looks and for the most part operates similarly to an extension for popular browsing programs like Chrome, Firefox, Safari and more.

However, if your regular free browsing add-on may or may not have some ad-generation functionality to help its developers financially support themselves, with hijackers the advertising materials that are put on your screen are ramped up to eleven! Constant intrusive page redirects, randomly generated advertising messages, discount offers, suggested downloads and so on and so forth is all likely to show up on your screen if a hijacker’s on your computer.

And, on top of that, the homepage, the search engine, the toolbar buttons as well as other elements of your browser may be altered to further increase the effectiveness of the advertising activity that the hijacker app is supposed to conduct. Some users, understandably, may actually think that their computer has been attacked by a malicious ransomware cryptovirus or Trojan horse infection since the intrusive activities launched by browser hijacker apps may indeed at times be really overwhelming and quite disturbing.

The good news is that this is probably not the case if any of the aforementioned symptoms are currently occurring on your computer. Hijackers are not typically intended to cause damage or to be used in cyber-criminal agendas. For example, the Musmentportal hijacker, despite being a really irritating newly released piece of software, is not really an innately harmful app. However, in case you are one of the many user who have recently had it installed on their machines, you likely want to remove it, in which case we would suggest that you take a look at the uninstallation guide down below.

The potential dangers of browser hijackers

As we previously pointed out, apps such as Musmentportal are different from Trojans, ransomware, spyware and other similar cyber threats in the sense that their purpose and abilities are not aimed at messing with your computer system and with the data that’s on your machine’s HDD or at causing some other issues concerning your virtual security and safety.

Despite that, however, we strongly advise you to get rid of Musmentportal if it is presently on your computer as this will help you protect your computer from potential future dangers and hazards. What we mean by that is the increased number of advertisements, page redirects, banners, pop-up requests and so on will invariably increase the chances of you landing on some sketchy web location with questionable contents. Since this is something you certainly would not like to happen, it is better if you uninstall Musmentportal using the guide in this article and/or the automatic removal tool we have provided on this page. Also, remember to stay away from danger on the Internet in the future – browser hijackers are mere annoyances in comparison to some of the worst malicious programs that you may come across online.
