Once the file encryption is achieved, Vvoo puts its own special text document (_readme.txt) into all the folders that store the encrypted files.
The alert specified by _readme.txt asking for the random os extremely comparable to the notifications given by other ransomware dangers coming from the DJVU family. The warning essentially indicates that the data has been encrypted and the only solution to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely real.
