Remove !Shadow Virus (+Decrypt .!Shadow files)

!Shadow – General Info

The !Shadow mean a ransomware-type infection. !Shadow was elaborated particularly to encrypt all major file types. When the file is encrypted people are unable to use them. !Shadow adds the “.!Shadow” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by !Shadow, will be renamed into “myphoto.jpg.!Shadow“. As soon as the encryption is finished, !Shadow places a special text file into every folder containing the encrypted data.

The message given by !Shadow text file requesting for the ransom is absolutely the like the statements given by other ransomware representatives. It literally discusses that the information is encrypted which the only way to bring back it is to use a a distinct decryption key. Regretfully, this is definitely true. The kind of cryptography mechanism used by !Shadow is still not appropriately examined. Still, it is absolutely certain that each victim might be given the specific decryption key, which is completely unique. It is difficult to bring back the files without the key available.

Another trick of !Shadow is that the victims cannot get to the key. The key is stored on a particular server run by the frauds related to !Shadow ransomware. To get the key and recover the important information people have to pay the ransom.

Nevertheless, irrespective of the asked for amount, people should keep away from paying the virus. Cyber frauds are unfair, so they tend to totally ignore 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 outcome and people just waste their money for absolutely nothing.

We highly encourage 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 !Shadow ransomware and to recover the data data totally free. Hence, the only best decision is to recover the lost information from the available backup.
