Suspecious JPEG Files

Hello,=0D
=0D
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).=0D
The sender is known to me, and I suspect he was trying to attack my compu=
ter (I recieved also an infected executable file from him just a short ti=
me before, and I didn't opened it).=0D
=0D
If anyone is interested in trying to analyse the files, I'd be mostly gra=
teful. Please contact me and I will send you the files. =0D

Thanks!
