Manually remove Genieo from a Mac computer by searching for and deleting its configuration and installation files. Alternatively, some security software can remove it automatically from the system. An official uninstaller is available, but it doesn't offer complete removal.
Verify the presence of Genieo by looking it up using the built-in utility Activity Monitor. If it is present, close the application, open a Finder window, enter "launchd.conf" in the search box, and modify the search by expanding the scope to include system files. Delete the file when it appears in the results. In addition, search for and remove ".app", ".plist" and ".dylib" files that are related to Genieo, and restart the computer. Be careful not to delete critical system files that keep the system stable and functional.
Security programs by Norton, Bitdefender and Sophos consider Genieo an unwanted adware and a threat to Mac systems. Some of these programs are available as free downloads and can remove Genieo after a complete system scan. Others offer real-time protection that automatically detects Genieo and stops it from installing onto computers. Genieo typically poses as a critical Flash Player update or video codec bundle, so Mac users should be wary of this type of download from an untrusted website.
