Suspecious JPEG Files


I recieved via e-mail two JPEG files, one of them was not opened properly (Default error message was displayed on the Windows Picture Viewer).
The sender is known to me, and I suspect he was trying to attack my computer (I recieved also an infected executable file from him just a short time before, and I didn't opened it).

If anyone is interested in trying to analyse the files, I'd be mostly grateful. Please contact me and I will send you the files.
