How to remove ExtendedCommand (Mac)

What is ExtendedCommand

ExtendedCommand is an adware-type application that targets Mac systems. It is part of the AdLoad malware family and is designed to generate revenue for its developers by running intrusive advertisement campaigns. These campaigns typically display adverts on visited websites and other interfaces. The presence of software like ExtendedCommand on devices may result in system infections, severe privacy issues, financial losses, and even identity theft. The ads displayed by ExtendedCommand mainly promote online scams, untrustworthy or harmful software, and even malware. Some intrusive adverts can be triggered (i.e., by being clicked) to execute scripts that perform downloads or installations without user consent. The gathered information can be monetized via sale to third-parties, leading to potential privacy issues. To remove ExtendedCommand from your Mac, you need to check for adware-generated files in the /Library/LaunchDaemons/ and /Library/LaunchAgents/ folders. Look for any recently-added suspicious files and move them to the Trash. In the preferences window, select “Extensions” and look for any recently-installed suspicious extensions. When located, click the “Uninstall”. It’s also recommended to use legitimate antivirus software to scan your Mac and eliminate possible malware infections.

How ExtendedCommand infects Mac computers

ExtendedCommand is often installed by users, either knowingly or unknowingly. This type of program is frequently offered through advertisements or bundled with other software, leaving the user puzzled about where the software came from. Some free downloads do not adequately disclose that other software will also be installed, leading to unexpected installations of adware like ExtendedCommand. Once installed, ExtendedCommand adds a browser extension to control your web browser and a profile to hijack your Mac settings. It changes your browser settings, such as your homepage and search results, and floods your screen with pop-up ads.
