Hello, I'm completely lost here, all my files have a .DOCM extension and open with just one application. How can I change all the extensions in one go?

Configuration: Windows / Chrome 74.0.3729.131

Windows has been infected by a ransomware / file-encrypting malware. These ransomwares are mainly caught by opening a malicious attachment in an email or by visiting a compromised webpage through web exploits.

Currently, there is not really a method to recover encrypted documents. If the data is very important, store it temporarily in a safe place because there may be a solution to recover it in the future.
You can still try the previous versions with Shadow Explorer
Keep the files for a few months and monitor this page for any potential solution in the future and a tool that allows you to recover the files: List of DecryptTools for ransomwares

First, make sure no threat is still active.
As a precaution, also consider changing all your passwords.

1°) FRST
Follow the FRST tutorial. ( take the time to read carefully - everything is well explained ).

Download and run the FRST scan, 3 FRST reports will be generated:
  • FRST.txt
  • Shortcut.txt
  • Additionnal.txt


Send these 3 reports to the site https://pjjoint.malekal.com/ and in return provide the 3 pjjoint links leading to the reports here in a new reply so we can review them.
