Arena ransomware is created to encrypt your personal files and demand bitcoin to recover the files. The ransom demand varies from different versions of the Arena ransomware.
Arena ransomware encrypts files on your computer and adds a string of unique characters to the extension of the encrypted files. For example, image.jpg becomes image.jpg.Arena
The decrypt text-file with instructions is placed on the Windows desktop: DECRYPT-FILES.txt
In most cases, it is not possible to recover the files encrypted by Arena ransomware without the intervention of the Ransomware developers.
The only way to recover files infected by Arena ransomware is to pay the ransomware developers. Sometimes it is possible to recover your files but this is only possible when the ransomware developers made a flaw in their encryption software, which unfortunately doesn’t occur frequently.
I do not recommend paying for the Arena ransomware, instead, make sure you have a valid FULL back-up of Windows and restore it immediately.

Having said that there are no tools at this moment to restore your encrypted files by the Arena ransomware because the decryption key used to recover your files is server-side meaning the decryption key is only available from the ransomware developers.
There is a Arena ransomware removal tool to remove the ransomware file.

You can try to restore files using the ID Ransomware decrypt tools. To proceed you need to upload one of the encrypted files and identify the ransomware that infected your computer and encrypted your files.
