Got hit with Sigma Ransomware. I was able to roll back the system using restore for a few days ago but the files are still locked.
If I roll back the system to an earlier date will that help or is there some way to unlock the files?

Some great work here. Let's hope it has been truly halted. If so, his work may be able to assist in the discovery of ways to stop future attacks more quickly.
