CROWN Virus Removal Guide (+Decode .CROWN files)

CROWN – Ransomware

The CROWN mean a ransomware-type infection. CROWN was elaborated specifically to encrypt all major file types. When the file is encrypted people are unable to use them. CROWN adds the “.CROWN” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by CROWN, will be renamed into “myphoto.jpg.CROWN“. As soon as the encryption is completed, CROWN places a special text file into every folder containing the encrypted data.

The message given by CROWN text file requesting the ransom is absolutely the like the statements given by other ransomware virus representatives. It actually mentions that the info is encrypted and that the only way to bring back it is to use a a special decryption key. Regretfully, this is definitely true. The type of cryptography mechanism used by CROWN is still not appropriately examined. Still, it is absolutely certain that each victim may be given the specific decryption key, which is totally distinct. It is impossible to bring back the files without the key available.

Another trick of CROWN is that the victims cannot gain access to the key. The key is saved on a specific server run by the frauds related to CROWN ransomware. To get the key and recover the important information people need to pay the ransom.

Nonetheless, irrespective of the requested amount, people should keep away from paying the virus. Cyber frauds are not fair, so they tend to totally disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive outcome and people just lose their money for nothing.

We highly advise that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack CROWN ransomware and to recover the data data for free. Hence, the only right decision is to recover the lost information from the available backup.
