Remove ExtendedService related files and folders

Now you need to try to find ExtendedService related files and folders, and then delete them manually. You need to look for these files in certain directories. To quickly open them, we recommend using the “Go to Folder…” command.

ExtendedService creates several files, these files must be found and removed. Below is a list of files associated with this unwanted program.

• /Library/LaunchDaemons/com.ExtendedService.system.plist
• ~/Library/LaunchAgents/com.ExtendedService.service.plist
• /Library/Application Support/.(RANDOM)/System/com.ExtendedService.system
• ~/Library/Application Support/.(RANDOM)/Services/com.ExtendedService.service.app

Some files created by ExtendedService are hidden from the user. To find and delete them, you need to enable “show hidden files”. To do this, use the shortcut CMD + SHIFT + . Press once to show hidden files and again to hide them. There is another way. Click Finder -> Applications -> Utilities -> Terminal. In Terminal, paste the following text: defaults write com.apple.finder AppleShowAllFiles YES

Press Enter. Hold the ‘Option/alt’ key, then right click on the Finder icon in the dock and click Relaunch.

/Library/LaunchAgents

This will open the contents of the “/Library/LaunchAgents” folder. Look carefully at it and pay special attention to recently created files, as well as files that have a suspicious name. Move all suspicious files to the Trash. A few examples of files: com.google.defaultsearch.plist, , search.plist, com.ExtendedService.service.plist, installapp.plist, com.net-preferences.plist, macsearch.plist and com.machelper.plist. Most often, browser hijackers, PUPs and adware create several files with similar names.

In the “Go to Folder…” window, type the following text and press Go:
/Library/Application Support

This will open the contents of the “Application Support” folder. Look carefully at its contents, pay special attention to recently added/changed folders and files. Check the contents of suspicious folders, if there is a file with a name similar to com.ExtendedService.system, then this folder must be deleted. Move all suspicious folders and files to the Trash.

Check for ExtendedService generated files in the “~/Library/LaunchAgents” folder

In the “Go to Folder…” window, type the following text and press Go:
~/Library/LaunchAgents

Proceed in the same way as with the “/Library/LaunchAgents” and “/Library/Application Support” folders. Look for suspicious and recently added files. Move all suspicious files to the Trash.
