As far as I know Chrome updates automatically unless you do some registry tweaks on Windows to prevent it. I'm not sure about other platforms. However, I think it has to be a running process in order to update. You're saying that Chrome was trying to start itself to update?
If you don't want auto-updates or the browser calling home all the time then I might suggest SRWare Iron, a Chromium fork.
