A browser hijacker is any piece of software that can add itself to the user’s browser and impose unwanted changes to the browser and flood it with intrusive adverts and page redirects. is one example of a hijacker – it is an app that functions similarly to a browser add-on for popular browsing programs like IE, Firefox and Chrome. However, the main difference between this piece of software and other extensions for browsers is that is typically regarded as unwanted due to the unpleasant activities it might conduct and the unwanted effects it might have on the user’s browser. Aside from the nagging advertisements and redirects to unknown web locations and pages, this intrusive software could also potentially replace certain elements of the user’s browser like the search engine, the toolbar, the starting page and the new-tab page. Usually, any such changes are imposed without the user’s direct permission and instead of actually improving the functionality of the browser, they mostly tend to promote the hijacker’s advertising campaigns. For instance, the new search engine is very likely to push certain sites and pages instead of showing relevant search results and the new starting page and toolbar are also usually added for the purposes of increasing the view count to certain web locations that the hijacker app is supposed to advertise. All in all, there’s usually little to be gained from the presence of a hijacker on your computer which is why it’s advisable if you get rid of or any other similar app in case you currently have such unwanted software on your computer. In the guide below, you can learn how to do that manually. The instructions will help you find the hijacker in your system and fully remove it from your computer and from your browser. However, if you think you might not be able to uninstall the app manually, you can always resort to the recommended security tool from this page that can automatically take care of the pesky hijacker for you. Regardless of what way you choose to handle the hijacker issue, however, we strongly advise you to eliminate the undesirable app as soon as possible.

Why it’s best if hijackers are removed

Obviously, a hijacker can be a really irritating software issue that could heavily affect your online experience in a rather negative way. This, however, isn’t the only reason why security experts recommend that any such apps get removed as soon as their presence in the computer system is noticed. The reason for that has to do with the potential security hazards that software pieces like could lead to. Now, we need to mention that here we aren’t talking about some insidious and malicious virus like a Ransomware threat or a Trojan Horse infection as hijackers really aren’t all that dangerous. However, because most hijacker apps tend to generate all kinds of ads and page redirects many of which have questionable and obscure origins, you can never be hundred percent certain that some of the advertising materials brought to you screen by or any other similar app won’t be hazardous and unsafe. One of the top most popular malware distribution methods that hackers tend to use is the so-called malvertising where unsafe online ads are used to lure users into unknowingly loading malicious viruses like Spyware, Trojans and Ransomware on their computer. This is why it’s always better to keep a safe distance from any online advertisements that look shady and unreliable which is, in turn, the reason why, in order to keep your PC safe, you should probably uninstall the hijacker from your system.

The distribution techniques used to spread unwanted software like

Keeping your PC clean is a very important rule if you want to ensure that your virtual safety and privacy are secured. Some of the more important tips that we can give you here is to never go to any sites or web locations with unknown or shady reputation. Never use download sources that might not be trusted and abstain from downloading stuff that is illegal and/or pirated. A common mistake that many users make is they tend to open attachments from spam messages and e-mails – something that could easily land you a hijacker like or even some other more dangerous program. Also, remember to uncheck any suspicious-looking bundled components that have been added as bonus content to the setup installers of programs you want to install. Be sure to customize the setup configuration when installing new software in order to ensure that nothing unwanted gets inside your system.
