My Billy.exe’s a part of “AutoRun Eater” (by Old McDonald’s Farm Freeware) which prompts and where optioned, destroys suspicious autorun.inf files pretty much wherever found (usually on pen drives is where malicious autorun.inf’s are pervasive, eg; bar311′s one that has the ability to basically crate havoc by screwing up your MBR such that the second you log on, Windows (actually the malicious autorun.inf’s resulting effects) immediately log’s you off, such that even safe mode may not allow you to access your machine. Of note my Billy.exe’s located inside my XP’s c:\program files\autorun eater
