Remove C-VIR Virus (+Decrypt .[coronavirus@foxmail.com].C-VIR files) – Dharma Ransomware

C-VIR Virus Ransomware

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

The message given by C-VIR text file asking for the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the Dharma clan. It actually mentions that the information is encrypted which the only way to bring back it is to use a a distinct decryption key. Unfortunately, this is definitely true. The kind of cryptography mechanism applied by C-VIR is still not correctly examined. Still, it is absolutely specific that each victim might be given the specific decryption key, which is completely unique. It is impossible to bring back the files without the key available.

Another trick of C-VIR is that the victims cannot get to the key. The key is saved on a particular server run by the frauds connected with C-VIR ransomware. To get the key and recover the important info people need to pay the ransom.

However, regardless of the requested amount, people need to stay away from paying the ransom virus. Cyber frauds are not fair, 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 typically does not give any positive result and people just lose their money for nothing.

We highly 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 C-VIR ransomware and to recover the data data free of charge. Thus, the just right decision is to recover the lost data from the available backup.
