What is "CDRUN.EXE"?

[Scooter]

A file named CDRUN.EXE is sitting in Deepburner's Autorun subfolder. It's 664,576 bytes and is dated 12/15/2005.

Is this file a valid part of Deepburner, and if so, why doesn't this executable have any accessible version or author info? This is a major malware flag.
