I didn’t have a chance to see if someone already posted this, but there is a less destructive way to turn off the updater.

Rather than compromising your install of google based software (thus removing your ability to run crucial updates for security reasons), you can just disable Google Software Update from checking for updates.

Just put this in your terminal
defaults write com.google.Keystone.Agent checkInterval 0
