ExtendedWindow Removal

ExtendedWindow is a browser hijacker that targets Mac computers

ExtendedWindow browser hijacker is also known as a redirect virus, and is mainly an infection targeting Macs. It isn’t directly damaging, so when it comes to infections, it isn’t that serious. Take into account, however, that hijackers lead you to dubious web pages so they could generate traffic and revenue, which is why they may be somewhat damaging. Even if the hijacker managed to install without you knowing it, you will notice it as soon as it’s inside the system. You’ll observe your browser acting unusually, search results will be a mixture of sponsored content and legitimate results and you’ll be randomly redirected. Users who are not familiar with browser hijacker might not associate the unusual behaviour with the infection. Simply researching the symptoms/page redirected to with Google generally leads users to the correct conclusion that it’s a hijacker.


Besides the strange redirects, hijackers also make modifications to browser’s settings. Another homepage/new tabs will greet you when you open your browser, and you might find it difficult to undo these modifications. Changing your browser’s settings permits hijackers to redirect you.

Hijackers need you to install them as they aren’t actually malware, even if many users regard them as such. Usually, users allow the hijacker to install themselves, though it occurs accidentally. Hijackers, and other pests such as adware and potentially unwanted programs (PUPs) are attached to freeware as added items, and when users install the freeware, they end up installing the added items as well. The following section of the article will explain how you can stop these undesirable installations.

Despite the fact that the hijacker is not particularly severe, you ought to remove ExtendedWindow. Not only will your normal browsing be disturbed, malware, scams among other dangerous content might be forced upon you.

How are hijackers installed

We’ve mentioned this above, but free programs is usually the reason hijackers are able to install. Bundling software is how this method is referred to, and it includes attaching infections like hijackers as additional offers to free programs. The dubious thing about this method is that the added offers are hidden from users but are permitted to install, unless users manually prevent them from doing so. It is worth noting that as long as you are attentive when installing programs, preventing these undesirable installations should not cause too many problems.

During free programs installation, choosing Advanced (Custom) settings is essential. The additional items will not be made visible if you choose Default settings. However, in Advanced, the offers won’t only be made visible, but you will be able to deselect them. To stop their installation, deselecting the boxes of those items is enough. Opting for Advanced settings and unchecking the offers doesn’t take a long time, while removing threats like browser hijackers would take much longer. In addition, if you are vigilant when installing applications, your computer won’t fill up with junk programs.

What does the hijacker do

Hijackers are not hard to see as they take over browsers (Safari, Google Chrome and Mozilla Firefox) and redirect you to random sites. It’ll modify your homepage and new tabs to its advertised page and you’ll be redirected to it whenever your browser is launched. The browser will also have another search engine. If you search through your browser address bar, you will be redirected to a hijacker’s promoted page and displayed modified search results. Keep your eye out for sponsored content being inserted among legitimate results. Hijackers intend to redirect users to sponsored websites so as to generate traffic and revenue. Bear in mind that being redirected to odd websites isn’t only irritating but also possibly damaging. Avoid engaging with any sponsored or advertisement content until you remove the hijacker. The site you’ll be led to by the hijacker won’t be reviewed, so you might end up on one that is harmful. A sponsored site may be encouraging you to participate in a scam or install malicious software. So even if hijackers aren’t directly damaging to the system, do not keep them installed.

We ought to also say that browser hijackers spy on users, and collect various data related their searches, visited sites, IP address and more. It is not strange for hijackers to permit third-parties access to that data as well, which is likely to not be something you want.

If you’re still uncertain about whether the hijacker is something you should delete, it installed on your Mac without explicit authorization, made modifications to your browser’s settings, and aims to redirect you to sponsored pages which might be hosting dangerous content. ExtendedWindow elimination is paramount, and the quicker you do it the better.
