I have tried the shade decrypter but it does not work.
The files all have the extension firstname.lastname@example.org. at the end that are encrypted.
It was shut down in the middle of messing up the data. We are sure it is gone. But the files need to be decrypted. The backup failed.
Any ideas? We are running Windows 7 and the file that infected the pc was Kaligula.caesar.exe
