Multiple Language Bin Files in Temp Folder

About a month ago my Temp folder started to contain multiple bin files for
every language imaginable. I think I've done a fairly good job of trying to
find a program installed that would be producing these files but no success.
I normally don't install language files if given a choice.
To my knowledge they're not causing any harm but I'd like to permanently get
rid of them. I'm now wondering if it's spyware??? Ad-Aware (paid version)
Spybot, Spyware Blaster, AVG Free Version, Spyware Dr, hasn't found any
spyware for a cpl months now.
When I run JV Power Tools and Registry Mechanic these files don't appear as
suggested deletions.
Can anyone shed some light on possibilities of why I've inherited these bin
files?
I did update Java but can't see a folder containing these named files.
I can't think of any other program that I would have installed
that would have multi language files. Thx for any suggestions.
