DEMON Virus – Details
The DEMON stands for a ransomware-type infection. The virus comes from the BlackKingdom ransomware family. DEMON was elaborated particularly to encrypt all major file types. Once the file is encrypted people are not able to use them. DEMON adds the “.DEMON” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by DEMON, will be renamed into “myphoto.jpg.DEMON“. As quickly as the encryption is completed, DEMON places a special text file into every folder containing the encrypted data.The message given by DEMON text file requesting the ransom is absolutely the like the statements given by other ransomware virus representatives belonging to the BlackKingdom clan. It actually points out that the information is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by DEMON is still not appropriately examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is absolutely distinct. It is difficult to restore the files without the key available.
Another technique of DEMON is that the victims cannot gain access to the key. The key is kept on a particular server run by the frauds connected with DEMON ransomware. To get the key and recover the important information people have to pay the ransom.
DEMON encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.

Nonetheless, irrespective of the asked for amount, people should stay away from paying the ransom. Cyber frauds are not fair, so they tend to completely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive result and people just waste their money for absolutely nothing.
We strongly encourage that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack DEMON ransomware and to recover the information data free of charge. Thus, the just best decision is to recover the lost data from the available backup.
