Your only option is to Restore your OneDrive as per these instructions.
Learn how to restore OneDrive to a previous time, if your files get deleted, corrupted, or infected by malware.

If this fails unless you have a personal backup on a CD or Flash drive there is nothing we can do.
You can always keep of copy of the compromised files on a Flash Drive.
Should a solution be found in the future you may be able to restore your files.
I would not place to much hope on this.
