Not if it's an Alternative Data Stream; you could launch it without any audit trail.  These are generally tied
to the main file, which could be anything (eg.  something.txt:trouble.exe).  These aren't detectable without
specifically looking.  You can fairly easily execute an ADS without it showing in the task list and other
niceties.  I'm not certain if common BU utilities actually save ADSs.
