SecuRom Copy Protection. It is a harmless file and comes installed with many game titles like GTA IV, Bioshock 1 & 2. If you remove it, you will have to remove the application. It also gets installed when ripping some Audio CD's as well.

Used by some games. Follow directions on link to delete it. A better way to prevent it from returning is to make a new folder and name it CmdLineExt02.dll. This is more effective that the method described on the link and doesn't require special attributes or admin rights to use.
