Strange files on my desktop

[nyartist63]

I recently downloaded several Adobe programs for use on my MacBook Pro (15", late 2008 version). I noticed after doing this (it could be just a coincidence) I now have three files which look like Excel files from their icons, but I can't open them to be sure. I can't delete them and I can't get info on them. They were never there before and I mention the Adobe downloads only because these files appeared about the same time. The names of the three file are: D2AF1000 64082000 9A733000

Can anyone tell me what they are and how to get rid of them? Thanks.
