Praying Computers?

Today we received what has to be one of the most unusual service requests ever in our 25 year history in the computer business.  A client called to report that their computer was praying. Actually they said it was reciting The Lords Prayer.  When I arrived on site, sure enough, after hearing heavy breathing coming out of the computer speakers, a voice did start to recite the prayer over and over for a couple of minutes.  Another user standing nearby reported hearing a gun shot as the praying stopped.

I ran several of our anti-malware programs and discovered 3 Trojans embedded in the system and removed them.   After a re-boot the praying stopped.

 It was obviously some sort of WAV file playing but the $64,000 question is how did it get on this business PC?  A search of various support blogs turned up previous references to this behavior but the causes listed varied from a extraneous audio file left over from a game, to malware and also to paranormal activity.  It stopped after I removed the malware so I'm going with answer #2 for now but if they call again with a recurrance of the problem, I'm bringing holy water and a priest on the next service call.
