How to remove CoordinatorBoost from Mac?

What is CoordinatorBoost?

CoordinatorBoost serves advertisements, collects sensitive information and promotes z6airr.com, and adjustablesample.com addresses (fake search engines). Simply said, this app functions as adware and a browser hijacker. Typically, users download and install apps of this type unknowingly, for this reason they are called potentially unwanted applications (PUAs).

CoordinatorBoost adware

Usually apps like CoordinatorBoost serve coupons, banners, pop-ups, surveys and/or other types of ads. Quite often those ads are designed to promote questionable websites, in some cases they can be designed to cause unwanted downloads and/or installations by executing certain scripts. In one way or another, ads that appear because of CoordinatorBoost or (or other PUAs) should not be clicked. Furthermore, this app is designed to change browser settings to z6airr.com (on Safari) and adjustablesample.com (on Chrome). In other words, CoordinatorBoost is designed to hijack browsers. As a rule, apps of this type do that by assigning a certain address (in this case z6airr.com or adjustablesample.com) as a homepage, default search engine and URL of a new tab so that users would visit it when they open a browser, enter search queries into URL bar and open a new browser tab. Z6airr.com generates results that may include links to untrustworthy pages, adjustablesample.com provides results generated by Yahoo (redirects to search.yahoo.com). In most cases users can undo the changes that were made by a browser hijacker only when that app is not longer installed on a browser and/or computer. Another problem with having CoordinatorBoost installed is that this PUA can read sensitive information such as credit card details, passwords, telephone numbers and some other data. Such information could be misused for various purposes, for example, to steal identities, accounts, make fraudulent purchases, transactions. If CoordinatorBoost is installed on a browser and/or operating system, then it should be uninstalled as soon as possible.

CoordinatorBoost is very similar to many other apps, for example, ExtendedLibrary, ExtendedProcesser and DynamicImprovment - all (or most) of them are designed to promote some fake search engine/its address, serve advertisements and collect sensitive information. Therefore, their users may become victims of identity theft, suffer monetary loss, lose access to various accounts, have problems related to online privacy, browsing safety and/or other issues. Therefore, such apps should never be downloaded and installed.

How did CoordinatorBoost install on my computer?

It is common that users download and/or install potentially unwanted apps together with some other programs. To be more precise, when PUAs are integrated in their setups as additional offers and users finish downloads and/or installations without declining them. Typically, such offers can be declined in "Advanced", "Custom" or other settings of setups. This distribution method of potentially unwanted apps is known as "bundling". Sometimes unwanted downloads and/or installations can be caused by clicking deceptive advertisements that are designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

Files and programs should be downloaded only from official pages and via direct download links. Other sources, tools (like unofficial pages, third party downloaders, installers, Peer-to-Peer networks like torrent clients, eMule, etc.) should not be used. Download and/or installation setups with settings like "Custom", "Advanced", "Manual" should be checked for offers to download and/or install unwanted apps. Advertisements on untrustworthy, unofficial pages should not be trusted/clicked - such ads can be designed not only to open other shady pages but also to cause unwanted downloads and/or installations. Any unwanted, suspicious extensions, add-ons and/or plug-ins that are installed on a browser should be removed. Programs of this kind that are installed on the operating system should be uninstalled as well. If your computer is already infected with CoordinatorBoost, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
