Zatrov Virus Removal Guide (+Decrypt .zatrov files) – DJVU Ransomware

Zatrov Virus – Details

The Zatrov mean a ransomware-type infection. Initially, it was revealed by Michael Gillespie. The infection comes from the DJVU ransomware family. Zatrov was elaborated specifically to encrypt all major file types. When the file is encrypted people are unable to use them. Zatrov adds the “.zatrov” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Zatrov, will be renamed into “myphoto.jpg.zatrov. As quickly as the encryption is completed, Zatrov places a special text file (such as “_readme.txt“) into every folder containing the encrypted data.

The message given by Zatrov text file asking for the ransom is absolutely the like the statements given by other ransomware representatives belonging to the DJVU type. It actually discusses that the info is encrypted which the only way to bring back it is to use a a distinct decryption key. Regretfully, this is absolutely true. The sort of cryptography mechanism used by Zatrov is still not properly examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is completely unique. It is difficult to restore the files without the key available.

“Don’t worry, you can return all your files!”, Zatrov message:

Don't worry, you can return all your files! virus

Another technique of Zatrov is that the victims cannot gain access to the key. The key is kept on a specific server run by the frauds related to Zatrov ransomware. To get the key and recover the important information people need to pay the ransom, which amounts to $980. To get the payment details users are advised to contact the frauds through e-mail or telegram. The alert likewise indicates that the users need to contact the Zatrov developers within 72 hours after the encryption happened. The message says that doing so users will get a 50% discount, so the ransom quantity will drop down to $490.

However, regardless of the asked for quantity, people need to stay away from paying the ransom. Cyber frauds are not fair, so they tend to totally ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom normally does not give any positive result and people just waste their money for absolutely nothing.

We highly advise that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Zatrov ransomware and to recover the data data totally free.
