DEcovid19bot Virus Ransomware

The DEcovid19bot stands for a ransomware-type infection. DEcovid19bot was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are not able to use them. DEcovid19bot adds the “.covid19” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by DEcovid19bot, will be renamed into “myphoto.jpg.covid19“. As soon as the encryption is finished, DEcovid19bot places a special text file into every folder containing the encrypted data.

The message given by DEcovid19bot text file requesting for the ransom is absolutely the like the statements given by other ransomware representatives. It actually mentions that the info is encrypted which the only way to restore it is to use a a special decryption key. Sadly, this is definitely true. The type of cryptography mechanism applied by DEcovid19bot is still not properly examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is absolutely unique. It is difficult to restore the files without the key available.

Another trick of DEcovid19bot is that the victims cannot gain access to the key. The key is saved on a particular server run by the frauds associated with DEcovid19bot ransomware. To get the key and recover the important information people need to pay the ransom.

Nevertheless, regardless of the asked for amount, people need to stay away from paying the ransom virus. Cyber frauds are unfair, so they tend to totally disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom usually does not give any positive result and people just waste their money for absolutely nothing.

We strongly recommend 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 DEcovid19bot ransomware and to recover the data data free of charge. Hence, the just right decision is to recover the lost information from the available backup.
