ExtendedService Mac Adware
ExtendedService is yet another potentially unwanted app designed to compromise macOS systems. If you have this app installed on your Mac, you may be experiencing multiple pop-ups and redirects to suspicious pages.
These pages may be deployed for various scams, such as “Your MAC Has Been Blocked Due To Suspicious Activity!” and “Win The New Playstation 5”. The first scam is an example of fake tech-support that triggers all kinds of fake warnings. The second type of scam may try to convince you to give away personal details, so that you can win a prize. Needless to say, you shouldn’t believe anything that these pages display.
Instead, you should inspect why and how the ExtendedService adware got installed on your Mac, and proceed towards completely removing it. Instructions to do so are available at the bottom of this removal guide.
Note. Unwanted apps such as ExtendedService have been known to generate fake pop-up warnings, claiming that “ExtendedService will damage your computer.” If you see this warning, don’t panic, as this only proves that adware has sneaked into your system. You should consider scanning your Mac to make sure that it is free of unwanted software.

Why Do I Have ExtendedService Installed on My Mac?
In many cases, adware programs appear after you have clicked on a fake update, like the ones for Adobe Flash Player. The pop-up may have suggested that your Flash Player is out of date, making you install a supposed update. Instead of getting any update, however, you got the ExtendedService adware.
Below you will find the most popular ways adware such as ExtendedService gets distributed across the web.
Bundling
A well-known method for adware distribution is called software bundling. It happens via various supposedly useful apps. Thanks to bundling, shady companies can promote potentially unwanted applications as additional downloads in freeware installers. These apps may not be malicious but they can be very irritating and difficult to remove. Furthermore, the longer an unwanted app is running on your system, the more vulnerable it becomes to other, more severe threats.
NB. It should be noted that bundling is not illegal but it often causes unwanted, additional downloads, even of legitimate products. To avoid it from happening, you should be more careful during the installation steps of freeware applications.
The moment ExtendedService adware obtains access to your Mac, it covertly modifies crucial system and browser settings. Changes aim to enable the app to generate intrusive ads on the affected device.
Adware developers monetize their shady apps through ads. Ads generated by ExtendedService may be hazardos, though, as some of them may open corrupted websites. Such sites may host online scams, rogue applications, and even malware.
You should better ensure that your system is secured by removing the adware from your Mac now.
Unsafe Browsing
Another possible installation method that could have brought ExtendedService to your Mac is unsafe browsing. If you tend to visit dubious websites, your browser may be flooded with ads promoting various shady products. If you are tricked by such an ad, you may end up downloading a product that you believe is useful. However, the program turns out to be ad-supported, or adware, as you start seeing various ads, banners, and pop-ups.
