Dirty Decrypt
First I used Kapersky Rescue Disk Boot CD to clean my computer of the actual FBI/Dirty Decrypt virus. Then I tried Kapersky rannohdecryptor.exe & pandaunransom.exe. Neither worked. Kapersky, when trying to compare a good file to a bad, kept saying the two files were different sizes! Well one is encrypted, the other clean. I would really just settle with paying the bad guys to decrypt my files, but I don't know how to get in touch with them...
