.nz Virus Ransomware
The .nz mean a ransomware-type infection. The virus comes from the MedusaLocker ransomware family. .nz was elaborated particularly to encrypt all major file types. When the file is encrypted people are unable to use them. .nz adds the “.nz” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by .nz, will be renamed into “myphoto.jpg.nz“. As quickly as the encryption is finished, .nz places a special text file into every folder containing the encrypted data.The message given by .nz text file requesting for the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the MedusaLocker clan. It literally discusses that the info is encrypted and that the only way to restore it is to use a a special decryption key. Unfortunately, this is definitely true. The type of cryptography mechanism applied by .nz is still not properly examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is absolutely distinct. It is difficult to bring back the files without the key available.
Another technique of .nz is that the victims cannot gain access to the key. The key is saved on a specific server run by the frauds connected with .nz ransomware. To get the key and recover the important info people need to pay the ransom.
.nz 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.

However, regardless of the asked for quantity, people must stay away from paying the virus.
