One of the most usual issues that users tend to face with their PCs is the presence of a hijacker app inside their systems that has latched onto whatever browsing program they use. Though many might not know it, browser hijackers aren’t actually scary and malicious malware threats in the sense that they do not seek to harm or cause any system damage or corrupt any of the data on the computer. Real malware threats out there such as Ransomware, Spyware, Trojans and other nasty viruses can be way more harmful than a mere browser hijacker. Nevertheless, if you an app on your PC that belongs to the hijacker group, it is likely that you’d experience random unpleasant page redirects, generation of obstructive ads and changes to your browsers (IE, Chrome, Opera, Firefox and so on and so forth) such as modified search engine, homepage, toolbar settings, new-tab page address, etc. Still, as unpleasant and as irritating as this might be, it is still not something that would directly put your PC at risk. The ads, the redirects and the changes to the browser settings are all imposed with the single purpose of allowing the people behind the hijacker to make money by advertising different products on the users’ screens. One important condition that needs to be met in order for the money to be earned, however, is that the users must, in one way or another, interact with the content displayed on their screens. They are supposed to click on the ads, interact with the pages they might get redirects to and open the promotional requests and notifications in order for the creators of the hijacker app to make money. With this in mind, it should be easy for you to now see why the adverts, the banners, the pop-ups and the page redirects coming from such apps tend to be so incredibly irritating and unpleasant and why they never seem to go away as long as the pesky app stays active on your computer.

Dealing with and its unpleasant effects on your browser

As you can already likely tell, the focus of this article is actually one particular representative of the browser hijacker category of software – the so-called If you need to have it remove, the guide down below can help you:

If you currently have the browser component on your computer, then you are likely constantly getting obstructed by its ads, its random page redirects and also your browser has likely had a number of changes imposed on it without you having agreed to that. In most cases, when users get faced with that, they wish to bring things back to normal – make the ads go away, make the redirects stop and override the unwanted changes made to their browsers. However, in the majority of instances doing that would only be possible if the hijacker gets taken away. This is precisely why you are advised to follow the instructions from the guide on this page in order to uninstall as this normally the only way to ensure that it is no longer capable of disrupting and annoying you. However, since here we aren’t talking about any regular program that could easily be uninstalled through the use of its uninstallation.exe file (mainly because hijackers usually tend to not have one), you will need to follow the detailed instructions from our guide in order to fully eliminate the undesirable component from your browser.

Regarding the dangers of browser hijackers and how to avoid such software from now on

As we already made it clear at the start of this article, a hijacker app isn’t something that’s necessarily dangerous on its own since it isn’t really a virus or some other nasty threat such as a Ransomware or a Trojan Horse infection. However, since there would normally be all sorts of ads on your screen while browsing if you have a hijacker on your PC and since not all of those ads can normally be trusted, it’s still better to get rid of any such software so as to keep your computer safe and secure.

It’s also important to learn how to keep away from hijackers in the future. Normally, such apps get distributed as added components put inside other program’s installers. The problem is that users oftentimes tend to ignore the customization settings in a given installer and simply install new programs using the default configuration which also normally allows for the installation of any bundled apps put inside the installer. If you, however, access the Advanced/Custom setup settings, you will be able to choose what to leave out should anything added to the installer looks fishy or undesirable. We highly advise you to do that in the future each and every time you are about to install something new so as to prevent any undesirable apps from getting inside your PC system.


Type Browser Hijacker
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)
Symptoms It’s actually rather difficult to not notice the presence of a hijacker once the ads and the redirects start flooding your screen…
Distribution Method The creators of such software components normally use program bundles and misleading online requests so as to get their products installed onto more machines.
