Google LLC Running in Background on Mac

This happened to me too. It added itself without any action on my part, and without any Google crud open, to my knowledge. How can I determine what added it, so that I can remove it with prejudice?

Update:

Ran `sfltool dumpbtm`

Update 2:

Contents of `com.google.GoogleUpdater.wake.plist` show it's Google Chrome related:

Still not sure how it got installed when I've got Google background services disabled.

If you delete the files, Google will just replace them and automatically enable them, not unlike malware. I've removed read/write permissions to the files. Untested in the long run, but should render them inoperable and unreplaceable:

chmod 000 ~/Library/LaunchAgents/com.google.*
