Apparently Norton thinks the autorun.inf file on my USB stick (which, guess what, launches the U3 system -- and which I don't use anyway as I have this kind of autorun functionality turned off in Windows) is a Trojan horse. *eyeroll* Every so often it keeps "quarantining" it when I plug it in (note: not every time, not even most of the time) and periodically asking me did I want to clean the file (note: often when it's not even inserted). grr.
