Remove QolkuzNbVcG Virus (+Decrypt .QolkuzNbVcG files) – Xorist Ransomware

QolkuzNbVcG Virus Ransomware

The QolkuzNbVcG stands for a ransomware-type infection. The virus comes from the Xorist ransomware family. QolkuzNbVcG was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. QolkuzNbVcG adds the “.QolkuzNbVcG” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by QolkuzNbVcG, will be renamed into “myphoto.jpg.QolkuzNbVcG“. As quickly as the encryption is finished, QolkuzNbVcG places a special text file into every folder containing the encrypted data.

The message given by QolkuzNbVcG text file requesting for the ransom is definitely the same as the statements given by other ransomware representatives coming from the Xorist type. It literally mentions that the information is encrypted which the only way to bring back it is to use a a distinct decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by QolkuzNbVcG is still not correctly examined. Still, it is definitely certain that each victim might be given the specific decryption key, which is completely unique. It is impossible to restore the files without the key available.

Another technique of QolkuzNbVcG is that the victims cannot get to the key. The key is kept on a particular server run by the frauds related to QolkuzNbVcG ransomware. To get the key and recover the important information people need to pay the ransom.

However, irrespective of the requested quantity, people need to keep away from paying the virus. Cyber frauds are not fair, so they tend to completely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive outcome and people simply lose their money for nothing.

We strongly 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 QolkuzNbVcG ransomware and to recover the data data for free. Hence, the just best decision is to recover the lost data from the available backup.
