How to remove ExtraWindow from Mac?

What is ExtraWindow?

ExtraWindow is an adware-type application. It is endorsed as an app, designed to enhance the browsing experience. It is allegedly capable of providing fast searches, accurate search results and etc. ExtraWindow operates by displaying various invasive advertisements. This application is also classified as PUA (potentially unwanted application), since most users install it unintentionally, i.e. they are tricked into installation. It is noteworthy, that adware often has data tracking abilities.

ExtraWindow adware

Adware-type applications display a wide variety of intrusive adverts, such as: pop-ups, banners, surveys, coupons and dozens of other types. These ads can seriously affect the browsing quality, diminish it by limiting browsing speed and site visibility (by overlaying page content). While that may sound as just an annoyance, invasive advertisements are deemed to be a threat. When clicked, they generate redirects to various sale-oriented, untrustworthy and even malicious websites. However, they can also execute scripts, designed to download/install unwanted or malicious content without users' consent. Some PUAs can track data; by spying on browsing activity (URLs visited, pages viewed, search queries typed and etc.), they can collect personal information (IP address, geolocation and real-life personal details). What is crucial to understand, is that this data is then passed onto third parties (possibly, cyber criminals), intent on misusing for financial gain. In summary, adware present on users' devices can not only cause various browser and systems invasions/infections, but also lead to severe privacy issues (even result in identity theft). To ensure device and user safety, all suspicious applications and/or browser extensions/plug-ins must be removed without delay.

PUAs are released by the thousand, adware - by no means a minority in numbers. Most unwanted applications share common traits, ones released by the same developers tend to be identical. WindowMixGenerelOpenFormalSearch are a few examples of similar adware-type apps to ExtraWindow. Usually, undesirable content looks legitimate and further lures users into installation by offering a broad array of "useful" and "beneficial" features. However, it must be emphasized that the only purpose of these malignant products is to generate revenue for their creators; therefore, the abilities and features they boast are rarely operational. Instead of working as advertised, PUAs run intrusive advertisement campaigns, generate redirects to hazardous webpages and gather private data.

How did ExtraWindow install on my computer?

The most common way of PUA proliferation is via the download/install setups of other software. The deceptive marketing method of packing regular programs with undesirable or malicious content is called "bundling". Unfortunately, this technique is often successful. PUAs and other malignant software invades systems, due to rushed download/installation processes (e.g. ignored terms, skipped steps and sections, used pre-set options and so on). Some unwanted applications have "official" websites, where they are typically endorsed as "free" and "handy". Invasive adverts (usually hosted by compromised webpages) once clicked can be triggered to execute scripts, designed to make rogue downloads/installs of PUAs. In summary, inattentive approach to downloading and installing, as well as reckless browsing habits are the main reasons behind various system invasions.

How to avoid installation of potentially unwanted applications?

Desired content (software, updates, tools, features, etc.) should always be researched to verify its legitimacy, before downloading/installing it. Only official and verified channels should be used for downloading. Using Peer-to-Peer sharing networks, unofficial or free file-hosting websites, third party downloaders and similar sources - is ill-advised, as they are more likely to offer undesirable/malicious software or programs bundled with such. It is recommended to treat download/installation processes with caution. That includes: reading terms, exploring options, using "Custom/Advanced" settings and opting-out from downloading/installing supplementary apps, tools and etc. Intrusive advertisements often look ordinary and harmless, however they redirect to unreliable sites (e.g. pornography, adult-dating, gambling and similar). If users experience ads/redirects of this type, they are strongly advised to check their system and remove all suspect applications and/or browser extensions/plug-ins immediately. If your computer is already infected with ExtraWindow, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
