Browser Hijackers are annoying and irritating apps capable of infiltrating pretty much any browser and flooding it with obstructive advertising materials like adverts, redirects to pages that the hijacker is trying to promote and random pop-ups and banners. This is quite similar to adware but in addition to the ads, a hijacker application is also likely to modify your browsers’ starting page and new-tab page addresses and maybe even its default search engine and toolbar settings. Since this isn’t really a virus like a Ransomware, a Worm or a Trojan Horse, it doesn’t matter if you are using a highly secure browser such as Safari, Chrome or Firefox – a hijacker would still likely be able to get inside of it if you accidentally install such an app on your computer. Now, it’s worth mentioning that some of the browsers out there like Chrome have some anti-hijacker features that may stop some hijackers from getting installed onto them but such features do not always against all hijacker-like apps. An important thing to note here is that a lot of browser hijackers are actually legitimate add-on-like apps for different browsers and even though they could be quite irritating with the imposed changes and the obstructive ads, they aren’t actually something inherently malicious. In fact, a lot of them may include useful features that some users might like. However, even if that is the case, the ads and the redirects as well as the imposed changes to the browser may be a bit too much for most users to tolerate.

Here, we will give you some details and instructions on how to successfully eliminate a hijacker app. The recently reported browser hijacker will serve us as an example since there have lately been a lot of complaints from many users regarding this particular piece of software.

Not malicious but still potentially risky

Unlike a threat such as a Ransomware cryptovirus, a Trojan Horse or a Spyware espionage tool, a hijacker like will mostly initiate nothing harmful or anything that can be regarded as malware activity. However, this doesn’t mean that apps like are perfectly safe and there are actually quite a few things that you need to remember about them. For instance, a lot of their adverts may not be what they seem – oftentimes you may get tricked into installing software on your PC that may be more of the same or you may get misled into buying overpriced low-quality product that you don’t need on your computer. Some redirect links and banners may even land you on sites and pages with potentially hazardous contents. Therefore, the extended presence of a hijacker in your system is not advisable and could potentially lead to a lot of different issues if you are not careful.

After you get rid of, make sure you stay away from anything obscure and questionable on the Internet and also remember not to visit any sites that seem unreliable or have low reputation, otherwise you may once again get an app like installed on your computer.

Detection Tool



We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading ComboCleaner to see if it can detect parasite files for you.

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.



To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading ComboCleaner
a professional malware removal tool.

The next step is to safely launch Safari again. Press and hold the Shift key while relaunching Safari. This will prevent Safari’s previously opened pages from loading again. Once Safari is opened up, you can release the Shift key.

On the off chance that you are still having trouble with scripts interrupting the closing of unwanted pages in Safari, you may need to take some additional measures.

First, Force Quit Safari again.

Now if you are using a Wi-Fi connection turn it off by selecting Wi-Fi off in you Mac’s Menu. If you are using a cable internet (Ethernet connection), disconnect the Ethernet cable.


Re-Launch Safari but don’t forget to press and hold the Shift button while doing it, so no previous pages can be opened up. Now, Click on Preferences in the Safari menu,

and then again on the Extensions tab,

Select and Uninstall any extensions that you don’t recognize by clicking on the Uninstall button. If you are not sure and don’t want to take any risks you can safely uninstall all extensions, none are required for normal system operation.

The threat has likely infected all of your browsers. The instructions below need to be applied for all browsers you are using.

Again select Preferences in the Safari Menu, but this time click on the Privacy tab,

Now click on Remove All Website Data, confirm with Remove Now. Keep in mind that after you do this all stored website data will be deleted. You will need to sign-in again for all websites that require any form of authentication.
