What is the Locked_File virus?

Locked_File virus is ransomware that encrypts files using cryptography algorithms, appends a new file extension to the encrypted files, and downloads a ransom note named !HOW_TO_UNLOCK_FILES!.html (or other) on Windows Desktop and in every folder it encrypted files in. The ransomware will append several different file extensions depending on the variant. Two of the current extensions it uses are  .[restoreassistant2@tutanota.com].locked and .[restoreassistant2@tutanota.com].locked_file.

Once the Locked_File virus has encrypted files it will download the ransom note on Windows desktop and in folders it encrypted files in. The ransom note basically explains to the victim what happened to their files and how to pay a ransom in order to decrypt their files the way the malware author wants them to:

All your files have been encrypted with strong cryptographic algorithm!

It means you will not be able to access them anymore until they are decrypted with your unique decryptor! If you will follow our instructions, we guarantee that you can decrypt all your files quickly and safely!

The Locked_File virus  is a console based program that is most likely operated by the developer after hacking into a computer.

Like most ransomware infections, the Locked_File virus is suspected to be spread via email spam messages that contain malicious .zip or .rar email attachments or by use of fraudulent social media messages. Once the email attachment is downloaded and executed it will spread the malware across the machine and begin its encryption process.
