I am Karsten and will help you with any malware-related problems.
It is true, your ID appears to be an online encryption ID.
These are your options without a backup:
1) Recovery: In rare cases ransomware fails to delete shadow volume copies or fails to delete the original files properly. You can try to recover files via shadow volume copies and file recovery software. 2) Repair: Certain file types, mainly video and audio files, can possibly be repaired with tools like MediaRepair. But these files will loose some data. 3) Wait: Backup encrypted files and a ransom note and wait in case a solution comes up later. Maybe law enforcement gets hands on the keys or the criminals publish the keys as it happened with, e.g., GandCrab. I suggest reading the news on this. Emsisoft will update their decrypter if that happens. 4) Pay: There is the option of paying the criminals, but we highly recommend against this step. You will just fund later attacks. You may also pay without getting your files back. These are criminals and as such not trustworthy.
Please let me know if you need help with any of the steps in 1) or 2). I will provide instructions for you.
