This is probably old news to a lot of you by now but I found it in one of the newsletters I subscribe to. The article describes how to completely disable autorun.inf on any media from automatically executing. Yes, there are times that itr will still execute, even if you think you've turned it off.

@="@SYS:DoesNotExist"
