All my files have been renamed to .arena and .nemesis Is there a way to restore files to the original state?
First of all, I have moved your question to the appropriate topic (so there is no confusion).
Second, it seems there is currently no solution to the Dharma (.arena files) ransomware.
Third, Nemesis has been spotted to roam around the Internet with new variants - do you mind sharing if there is a ransom note (or a ransom note picture) with it? With that there might be more to go on, although I believe previous variants of Nemesis were not decryptable.
Here is an article about Nemesis and its first variant: Remove Nemesis Ransomware and Restore Encrypted Files
See if it's of help and provide more information to try and help you!
