How to remove BoostCoordinator from Mac?

What is BoostCoordinator?

In most cases users download and install apps like BoostCoordinator unintentionally, unknowingly, for this reason they are called potentially unwanted applications (PUAs). This particular app functions not only as adware but also as a browser hijacker. It means that it serves advertisements and promotes address of some fake search engine by changing browser settings. Also, it collects sensitive information.

BoostCoordinator adware

As a rule, when adware is installed on a browser and/or operating system, it serves banners, coupons, pop-ups, surveys and/or other advertisements. It is common that those ads are designed to promote (open) questionable websites, also, in some cases they can execute scripts designed to cause unwanted download and/or installation. As mentioned in the introduction, BoostCoordinator functions as a browser hijacker: it changes browser settings such as address of a homepage, default search engine and/or new tab to an address of some fake, questionable search engine. Typically, such search engines do not generate unique results (provide results generated by some other, legitimate search engine) or they generate results that may include links to untrustworthy pages. It is worthwhile to mention that users can remove address of a fake search engine only when the app promotes it is no longer installed. Another problem with BoostCoordinator adware/browser hijacker is that it can collect data such credit card details, passwords, telephone numbers and other sensitive information. It could be misused for malicious purposes, for example, to steal identities, personal accounts, make fraudulent purchases, transactions. Therefore, it is strongly recommended not to have BoostCoordinator installed on a browser and computer.

A couple more examples of PUAs like BoostCoordinator are InitialWindow, ConnectionFormat and ExpandedSkill. Usually they are advertised as legitimate, useful, etc. Although, most of them are designed only to generate revenue for their developers by serving ads, promoting shady addresses and/or gathering various data. Also, users who have installed such apps are exposed at issues related to browsing safety, privacy, they may even become victims of identity theft, suffer monetary loss, or experience other serious problems. If such app is already installed on a browser and/or computer, then it should be uninstalled immediately.

How did BoostCoordinator install on my computer?

Sometimes users download and/or install PUAs by clicking deceptive advertisements that are capable of executing certain scripts. Although, more often they download and/or install such apps alongside with programs that they download and/or install willingly. It is common that developers distribute PUAs by including them in download and/or installation setups of other programs as additional offers. The problem is that not all users notice those offers/decline them. Usually they can be declined in "Advanced", "Custom" and other similar settings of download and/or installation setups. When users download and/or install programs without changing them, they allow for PUAs to be downloaded and/or installed too.

How to avoid installation of potentially unwanted applications?

It is common that PUAs (or even malicious applications) are distributed through Peer-to-Peer networks like torrent clients, eMule, unofficial pages, third party downloaders, installers and other download and/or installation sources, tools of this kind. Programs (and files) should be downloaded and/or installed only from official pages and via direct links. Also, quite often download and installation setups include settings like "Custom", "Advanced" that can be used to decline offers to download and/or install various potentially unwanted applications. It should be done before completing downloads and/or installations. Advertisements that are displayed on shady pages can open questionable websites or cause unwanted downloads, installations. For this reason such ads should not be clicked. If there are any unwanted, suspicious extensions, add-ons and/or plug-ins installed on a browser, then they should be removed from it. Programs this kind that are installed on the operating system should uninstalled too. If your computer is already infected with BoostCoordinator, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
