You appear to be dealing with Radamant Ransomware
encrypts data using AES (Advanced Encryption Standard)
Any files that are encrypted with the first version of Radamant ransomware will have the .RDM
extension appended to the end of the filename. Any files that are encrypted with the second version of Radamant will have the .RRK
extension appended to the end of the filename. When Radamant is first installed, it will copy of itself to C:\Windows\directx.exe and create some autorun registry keys to make the infection start every time you login to Windows. When the ransomware has finished encrypting files it will create a file called YOUR_FILES.url. There are now rumors of a third version
that we have not seen yet. More information in this BC News Article...New Radamant Ransomware Kit adds RDM Extension to Encrypted Files

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 support topic discussion. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion...this topic is closed.
