Remove DEWAR Virus (+Decrypt .[mr.helper@qq.com].dewar files) – Phobos Ransomware

DEWAR Virus Ransomware

The DEWAR mean a ransomware-type infection. The virus comes from the Phobos ransomware family. DEWAR was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. DEWAR adds the “.[mr.helper@qq.com].dewar” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by DEWAR, will be renamed into “myphoto.jpg.[mr.helper@qq.com].dewar“. As soon as the encryption is finished, DEWAR places a special text file into every folder containing the encrypted data.

The message given by DEWAR text file requesting the ransom is definitely the like the statements given by other ransomware representatives coming from the Phobos family. It actually points out that the information is encrypted which the only way to bring back it is to use a a special decryption key. Unfortunately, this is absolutely true. The kind of cryptography mechanism applied by DEWAR is still not appropriately examined. Still, it is definitely certain 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 technique of DEWAR is that the victims cannot gain access to the key. The key is saved on a particular server run by the frauds connected with DEWAR ransomware. To get the key and recover the important information people need to pay the ransom.

Nevertheless, irrespective of the requested quantity, people should stay away from paying the ransom. Cyber frauds are unfair, so they tend to entirely disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom normally 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 certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack DEWAR ransomware and to recover the data data for free. Hence, the only best decision is to recover the lost information from the available backup.
