How irritating is this problem? (3 votes, average: 5.00)

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

Nowadays, it seems inevitable to get ads in your Firefox, Chrome or whatever other browser you could be using as the majority of sites out there use them either to support or to earn extra revenue for their creators. Either way, online ads are here to stay and there isn’t too much you could do against them. Maybe you can get an ad-blocker that would stop at least some of the nagging pop-ups and banners or simply avoid those sites that tend to be overly aggressive with their ads. The real problem, however, comes when you aren’t visiting any site that generates a lot of ads and yet you are still getting your screen flooded with all kinds of blinking boxes, flashy messages and page redirects that seem to be coming out of nowhere. Changes to the starting page and the search engine tool as well as to the toolbar could also occur in such a case because, if this is the situation you are presently dealing with, there’s most likely a browser hijacker in your system. A browser hijacker is a specific type of software that is supposed to generate revenue for its developers through web advertising. All the ads that such an application would put on your screen are there to earn money for the creators of the unpleasant piece of software. Most users do not actually realize when such a pesky app has gotten inside their PC and onto their browser due to the rather sneaky and stealthy methods that hijackers utilize in order to get distributed. However, once inside the computer, a browser hijacker would certainly not try to hide its presence – quite the opposite. A piece of software that belongs to this category of apps would not stop nagging you with its flashy banners, irritating ads, obstructive pop-ups and unpleasant page redirects during the time it is active on your computer. In most cases, the only way you could effectively deal with this intrusiveness and put an end to the seemingly endless ads streaming would be by uninstalling the unwanted software from your computer. To help you with that, we have prepared a specialized guide for eliminating one of the currently most popular browser hijacker apps, the so-called Removal

The reason why is the focus of our guide and of the whole article has to do with the fact that this is one of the newer browser hijackers out there and, as such, it is currently very widespread. If you are reading this, then the most likely reason for that is because you too have this irritating app on your PC. If that’s the case, feel free to make use of the guide from this page. Aside from the manual instructions in it, you could also find a specialized removal program that can help you get rid of the intrusive and also aid you in keeping your computer safe and clean in the future.

Hijackers and viruses – what’s the difference?

A hijacker app, though intrusive and unpleasant isn’t actually a virus. Pieces of software like are different from insidious malware threats such as Trojans, Spyware, Ransomware and so on, because they are usually not illegal and are normally not used for any actual malicious activities. The ads, the unauthorized browser changes and the nagging page redirects can certainly be unbearably irritating, there’s no argument here. However, a hijacker wouldn’t actually be used for anything really harmful in the majority of cases. That being said, you are not supposed to trust software elements like Though not inherently malicious, their ads, imposed browser components and their page redirects are not something we would advise you to interact with. Clicking on random pieces of online advertising content is never a good idea as it could expose your machine to all sorts of nasty cyber threats like Ransomware, Rootkits, Worms and so on and so forth.

Remember to keep your PC clean!

A clean PC normally also means a safe PC so be sure that, after you remove, you do not allow any more hijackers to sneak inside your system. But how can you ensure that this never happens again? Well, for starters, be more careful with what you do online – sites that do not seem trustworthy are to be avoided. Same goes for messages that might be spam and ads and offers that seem unreliable or too-good-go-be-true. A great tip is to always go for the Advanced installation option when installing new software. Once in the Advanced setup menu, look for any added bundled apps and disable the ones that seem undesirable to avoid installing anything unwanted on your PC alongside the main program from the installer.


Type  Adware/Browser Hijacker
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)
Symptoms  Usually, the main symptoms would be the changes to your browser and the random ads that seem to pop-up out of nowhere while you are browsing.
Distribution Method Hijackers can get on your PC through spam messages, alongside low-quality downloads and installation bundles and also with the help of malvertising ads.
