Remove PROM Virus (.PROM[prometheushelp@mail.ch] Files Ransomware) – Thanos Ransomware

PROM Virus Ransomware

The PROM stands for a ransomware-type infection. The virus comes from the Thanos ransomware family. PROM was elaborated specifically to encrypt all major file types. When the file is encrypted people are unable to use them. PROM adds the “.PROM[prometheushelp@mail.ch]” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by PROM, will be renamed into “myphoto.jpg.PROM[prometheushelp@mail.ch]“. As quickly as the encryption is finished, PROM places a special text file into every folder containing the encrypted data.

The message given by PROM text file requesting for the ransom is definitely the same as the statements given by other ransomware virus representatives belonging to the Thanos family. It actually mentions that the info is encrypted which the only way to bring back it is to use a an unique decryption key. Regretfully, this is definitely true. The sort of cryptography mechanism used by PROM is still not correctly examined. Still, it is definitely particular that each victim may be given the specific decryption key, which is totally unique. It is impossible to bring back the files without the key available.

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

However, regardless of the requested quantity, people must stay away from paying the ransom virus. Cyber frauds are unfair, so they tend to entirely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom typically does not provide any positive result and people simply lose their money for absolutely nothing.

We strongly encourage 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 PROM ransomware and to recover the data data totally free. Therefore, the only best decision is to recover the lost data from the available backup.
