Remove Cov19 Virus (+Decrypt .cov19 files) – Scarab Ransomware

Cov19 – Ransomware

The Cov19 mean a ransomware-type infection. The infection comes from the Scarab ransomware family. Cov19 was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are not able to use them. Cov19 adds the “.cov19” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Cov19, will be renamed into “myphoto.jpg.cov19“. As soon as the encryption is completed, Cov19 places a special text file into every folder containing the encrypted data.

The message given by Cov19 text file asking for the ransom is definitely the same as the statements given by other ransomware representatives coming from the Scarab family. 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. Sadly, this is absolutely true. The type of cryptography mechanism used by Cov19 is still not appropriately examined. Still, it is definitely 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 technique of Cov19 is that the victims cannot access to the key. The key is kept on a particular server run by the frauds related to Cov19 ransomware. To get the key and recover the important information people need to pay the ransom.

However, regardless of the requested quantity, people need to keep away from paying the ransom virus. Cyber frauds are not fair, so they tend to totally ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom typically does not provide any positive outcome and people just waste their money for nothing.

We strongly recommend 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 Cov19 ransomware and to recover the information data totally free. Hence, the just best decision is to recover the lost information from the available backup.
