- "Google Updater Helper" - Firstly started by /Library/Preferences/loginwindow.plist (from here) and subsequently by launchd - (seen by running launchctl list | grep com.google.Updater.helper) - more info on startup from Apple.
Removal: edit/remove the google item in that file using property editor/textedit/Pacifist - "googleml-modwatch" - Started by launchd from: /Library/LaunchDaemons/com.google.GoogleML.plist.
Removal: rename com.google.GoogleML.plist to com.google.GoogleML.plist.off e.g.:
sudo mv /Library/LaunchDaemons/com.google.GoogleML.plist /Library/LaunchDaemons/com.google.GoogleML.plist.off - "GoogleSoftwareUpdateDaemon" - another launchd startup
Removal: sudo mv /Library/LaunchDaemons/com.google.keystone.daemon.plist /Library/LaunchDaemons/com.google.keystone.daemon.plist.off - "GoogleSoftwareUpdateAgent" - another launchd startup
Removal: sudo mv /Library/LaunchAgents/com.google.keystone.agent.plist /Library/LaunchAgents/com.google.keystone.agent.plist.off
Then Restart and they should all be gone.... You can still manually run the updates when you want to by running:"/Library/Google/Google Updater/Google Updater.app".
