In most of the cases where users suddenly realize that the search engine, the starting page, the toolbar or some other aspect of their default browser has gotten altered without their approval, the main cause behind such unauthorized alterations normally is a piece of software that falls under the so-called browser hijacker category. Such apps tend to “target” pretty much every browser that you could think of since they are normally not browser-specific unlike most other browser extensions and could get added to all kinds of browsers.

Some popular examples are Chrome, Opera, Firefox, Edge, IE and so on and even though some browsers like Chrome have protection features against unauthorized modifications, oftentimes hijackers still manage to “invade them”. Aside from the changes that a hijacker is likely to impose to your browser, random page-redirects, intrusive ads generation and display of nagging banners, pop-ups and blinking online messages are also to be expected. All in all, a browser hijacker app is a piece of software that is supposed to advertise stuff on the user screen and in most of the cases the ways in which those browser components could carry out their task are various.

It should be obvious, especially for those of you who currently have such software on their computers, that hijackers can be quite irritating and therefore unwanted by most of the users. This, however, does not make them actual viruses or malicious programs similar to Trojan Horse infections and Ransomware cryptoviruses. Hijackers are still relatively harmless despite their intrusiveness and their unpleasant traits. That said, it’s still better if you don’t allow such software to stay present in your system for longer periods of time – the intrusive ads, the page-redirects and the changes to your browsers could really make it quite difficult to find whatever it is you are looking for on the Internet. Also, there are some security concerns to be had when it comes to hijackers despite their overall non-malicious nature which is another reason why removing them is preferable in most of the cases.

It is important to understand that a hijacker usually can’t be removed by a simple uninstallation. Furthermore, in most cases, there won’t be any option to simply “uninstall” the pesky app mainly because those pieces of software are purposefully programmed to be tricky to eliminate. After all, the longer they stay present on a given PC, the higher the potential profit that they’d be able to generate from clicks and visits to the ads and sites that they seek to promote and advertise. This is, in fact, the whole purpose of those apps and even though some of them might actually offer certain functions to the end-users in order to be more presentable and, therefore, desirable, most browser hijackers are still mostly an unwanted annoyance that few users would be willing to put up with. Of course, in the end, the decision on whether to remove or keep the hijacker is all yours to make but here is where we must tell you something more about the potential risks related to apps like

A piece of software like, as we said, is no Ransomware, Trojan Horse, Spyware or some other type of virus or malicious program. However, it’s pretty much always a security risk if you have random adverts, banners and page-redirects popping-up on your screen since some of them may be unsafe. This means that even though might not be purposefully seeking to harm your system, it might indirectly expose it to a number of hazards which makes it better to simply remove the hijacker so as to prevent this from happening.

Methods of distribution of hijackers and other undesirable software

Clicking on some sketchy online offer, agreeing to download some obscure app or program from some questionable site, interacting with spam messages and visiting fishy web locations could easily land you unwanted software components like The same could also happen if you normally use the Default setup configuration when installing new software on your PC. This is because in many of the cases, the programs people install tend to have additional components bundled within their installers. Sometimes, such components could be browsers hijackers the likes of If you, however, choose to use the Advanced installation menu, you should have the opportunity to see what bundled apps there are and manually leave out anything that might look unwelcome.

This piece of software is a good example of what a browser hijacker really is. Lately, there have been quite a lot of complaints concerning which is why the guide that follows will show you how to remove it:
