One of our computers got infected by ransomware and it encrypted a lot of dropbox files on that machine which were then updated to the entire dropbox. I know how to manually find the old version of each file but it's taking a long time to do them one at a time. Is there a restore point option to go back to how all the files were prior to the event taking place? I have sent in a ticket/request to Dropbox support but it looks like it will take 24-48 hours to get a response.
