Remove Chos Virus (.Chos Files Ransomware)

Chos Virus Ransomware

The Chos stands for a ransomware-type infection. Chos was elaborated specifically to encrypt all major file types. Once the file is encrypted people are not able to use them. Chos adds the “.Chos” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Chos, will be renamed into “myphoto.jpg.Chos“. As soon as the encryption is finished, Chos places a special text file into every folder containing the encrypted data.

The message given by Chos text file requesting the ransom is definitely the like the statements given by other ransomware virus representatives. It actually mentions that the info is encrypted which the only way to bring back it is to use a a distinct decryption key. Regretfully, this is definitely true. The kind of cryptography mechanism applied by Chos is still not properly examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is completely distinct. It is impossible to restore the files without the key available.

Another technique of Chos is that the victims cannot get to the key. The key is saved on a specific server run by the frauds related to Chos ransomware. To get the key and recover the important info people have to pay the ransom.

Nonetheless, regardless of the requested quantity, people should stay away from paying the virus. Cyber frauds are unfair, so they tend to completely disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive result and people just waste their money for nothing.

We strongly advise that you do not contact these crooks and absolutely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Chos ransomware and to recover the information data free of charge. Thus, the only best decision is to recover the lost data from the available backup.
