"Extra Window"

The Extra Window will redirect your browser searches.

Chrome, Firefox, Internet Explorer, Microsoft Edge as well as most of the other popular browsing programs are regarded as generally safe. However, a browser hijacker such as Extra Window could easily invade them and totally change the way they operate in its attempt to launch its aggressive online advertising activity. Almost immediately after being installed, the pesky application would start to interrupt your normal web browsing with different irritating ads, pop-up messages and banners that cover every page that you may visit. Additionally, and most commonly without your permission, Extra Window tends to install a new toolbar, a sponsored homepage domain or a new third-party search engine to your default browsing program which usually perform automatic redirects to specific sponsored web platforms and links. All these changes could be extremely frustrating but what is even more annoying is the fact that there is no quick option to remove and uninstall them. Reinstalling the browser or switching to another one will most likely not get you rid of the browser hijacker, because its components should be removed and carefully uninstalled from the system itself.

Extra Window targets Mac

Extra Window is known to be a browser hijacker. Numerous complaints about Extra Window include webpage redirects, unwanted advertisements and unapproved changes to the user’s browser.

The browser hijacker applications are not some super dangerous and harmful pieces of software. They greatly differ from malicious programs such as Rootkits, Trojans or Ransomware because their purpose is not to perform a cyber crime but to advertise different products and websites/webpages. Still, despite not being considered as serious computer threats, applications such as Extra Window are still mostly seen as potentially unwanted. This is mainly because of their rather aggressive online advertising approach which involves unwanted browser changes, automatic redirects and unstoppable exposure to third-party ads, offers and links. Many users find this to be extremely frustrating as they get forced to constantly deal with the pop-ups, the newly installed search engine tools or toolbars while trying to perform a normal web search. Another issue that people with browser hijackers in their system commonly face is browser sluggishness, unresponsiveness and frequent crashes. Some people also fear from accidentally clicking on infected or misleading ads and links while trying to deal with the pop-up streaming on their screen. Because of this, many prefer to simply uninstall the hijacker in order to reduce the risk of landing on something hazardous. Keep in mind, though, that if you want to keep your PC free from nagging ads and unwanted browser changes, it is not enough to remove the hijacker once. You also have to avoid its most common sources (such as free downloads, automatic installers, application bundles, torrents, spam, etc.) and pay close attention to every new component that asks you to make changes to your computer or your browser.

Extra Window Virus App Removal


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.
