You are dealing with TeslaCrypt Ransomware
. Unlike other ransomware that typically target images, documents, videos, and applications databases, TeslaCrypt also targets over 40 different video game related files. Any files that are encrypted will have the .ecc extension
added to the end of the filename. At this time there is no fix tool and no way to decrypt the files
You can submit a sample of an encrypted file here: http://www.bleepingcomputer.com/submit-malware.php?channel=3
with a link to this topic.
You can also submit samples of suspicious executables or any malware files that you suspect were involved in causing the infection. Doing that will be helpful with analyzing and investigating.
There is an ongoing discussion in this topic: New TeslaCrypt Ransomware sets its scope on video gamers
Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in that topic discussion.
