Not wanting to tread on anyone's feet here, but apparently this is a hoax. I did a search on it & all I got back was sites saying it is a hoax, that the file is a valid one (a Java debugger manager), although deleting it shouldn't cause any major problems.
Anyhoo, this could be wrong too, so everyone look into it themselves & decide. Kudos to Stuart for at least bringing it to our attention :)
Oh, and apologies if someone has already said this... I've not checked the other forum it's posted in yet :)
