This page aims to help you remove Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

The majority of browser extensions and add-ons out there are helpful software tools that are supposed to improve your overall experience while surfing the Internet by offering you some useful function or making your browser safer and better optimized for your specific needs. However, there are also those extension-like apps that would actually worsen the way your browser functions by filling its tabs with nagging ads and page-redirects and/or by making unwanted alterations to the search engine tool of the browser, to its starting page or to the toolbar. Pretty much every browser could get affected in such a way so it doesn’t matter what your default browsing program is – Chrome, IE, Firefox, Edge as well as most other browsers out there are all susceptible to this kind of unpleasant effects caused by a specific type of software components that are usually referred to as browser hijackers. As the name suggests, an app of this kind is capable of hijacking your browser without your permission. But what does “hijacking” mean? Is it similar to a malware infection with a cyber threat such as a Trojan Horse or maybe a Ransomware virus? Fortunately, this isn’t what we are talking about here. For all intents and purposes, browser hijacker apps are not in the same category of software as actual malware viruses such as the ones we mentioned above. Of course, this certainly doesn’t meant that hijackers are not unwanted. Quite the contrary – pretty much every user who comes to face the effects of a browser hijacker on their main browser, quickly realizes that the best thing they could do in such a case is to remove the pesky app and, in that way, bring the browser back to its regular state.

This brings use to the main topic of this article – the removal of is a piece of software that, similarly to most other browser hijackers, can get added to your browser in order to tinker with its settings and display nagging ads on your screen while your browser is being used. Understandably, if you currently have this annoying component inside your PC, you’d most likely want to have it uninstalled at once. If that’s indeed the case with you, we advise you to have a look at our removal guide.

If you think that you might not be able to manually deal with the steps from the guide, remember that you can always ask for pour assistance through our comments section on this page. Also, you might have noticed that there’s a removal program added to the guide – this is a professional removal tool that can take care of for you so you could also use that as means of eliminating the intrusive piece of software that you are currently struggling with. The important thing is to make sure that is removed from your machine because hijackers, though not rel viruses, could actually sometimes make your machine less secure.

Dangers of browser hijackers is likely not going to try to steal or encrypt your data, corrupt your OS, block your antivirus program or spy on you – those are criminal activities normally carried out by malicious malware threats like Trojans, Ransomware, Spyware and Rootkits. In comparison, hijackers are mainly utilized within the online marketing industry as means of allowing for greater exposure of certain products, sites, online stores and web services through the intrusive and oftentimes aggressive advertising campaigns that such apps tend to conduct. However, your PC is likely to stay unharmed. The problem here is that the different ads you might come across on your screen while is active inside your PC might be unsafe or at least might link you to some sketchy sites or display to you misleading web offers and download requests. With that in mind, it should be pretty obvious why you ought to get rid of at once instead of allowing you to operate from within your system.

The key to keeping your machine clean in the future

Of course, it’s always better to prevent the installation of hijackers in the first place. But how can one do that? Well, for starters, by avoiding questionable download sources and websites in general and also by never opening any obscure spam messages and fishy-looking ads. One very important thing that a lot of users tend to forget is to always go for the detailed setup options such as Advanced, Custom or Manual when setting up new software on your PC. Through those options, you should be able to see if there aren’t any bundled and potentially unwanted apps put inside the main program’s installers and leave them out if you think they are not to be trusted.
