It also warns you when you are installing it. So it's not "silent", just rather quiet. That said, auto update is the only way I've seen to effectively distribute security patches to the masses. I'd prefer an email. I just don't like the whole concept of a service that is constantly sucking CPU and phoning home to check for a patch that comes out every few months. Adobe, Java, Google, Windows, Apple, and just about every "security" product out there- they are all obnoxious software that could at least have the decency to be cron jobs that run once per week.
