Remove CALVO Virus (.[seamoon@criptext.com].CALVO Files Ransomware) – Phobos Ransomware

CALVO Virus Ransomware

The CALVO mean a ransomware-type infection. The infection comes from the Phobos ransomware family. CALVO was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are not able to use them. CALVO adds the “.[seamoon@criptext.com].CALVO” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by CALVO, will be renamed into “myphoto.jpg.[seamoon@criptext.com].CALVO“. As soon as the encryption is finished, CALVO places a special text file into every folder containing the encrypted data.

The message given by CALVO text file requesting the ransom is absolutely the same as the statements given by other ransomware virus representatives belonging to the Phobos clan. It literally points out 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 type of cryptography mechanism applied by CALVO is still not correctly examined. Still, it is definitely specific that each victim might be given the specific decryption key, which is completely unique. It is difficult to bring back the files without the key available.

Another trick of CALVO is that the victims cannot access to the key. The key is kept on a specific server run by the frauds associated with CALVO ransomware. To get the key and recover the important information people have to pay the ransom.

However, irrespective of the asked for quantity, people must stay away from paying the ransom virus. Cyber frauds are unfair, so they tend to completely 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 outcome and people just lose their money for absolutely nothing.

We strongly 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 CALVO ransomware and to recover the information data totally free. Hence, the only best decision is to recover the lost information from the available backup.
