How to remove Desu ransomware

Desu ransomware – malware which modifies the Windows Registry to perform damaging actions

Desu ransomware is a dangerous virus which can initiate numerous changes to computer's Windows Registry. Once activated, the file-encrypting virus blocks various data and adds the .desu file extension to each corrupted file. It can affected audio, video, text documents, and similar data which becomes unusable because of RSA or similar encryption algorithm. After such intruding activity, Desu virus displays a ransom message which announces about the secret infiltration of malware and the corruption of numerous files. Cybercriminals urge users to contact them via j0ra@protonmail[.]com and transfer $200 in Bitcoin in order to receive a decryption key for encrypted data.

Each time Desu ransomware creators manage to invade the computer system, they use different and unique encryption key to lock target victim's files. Encryption and decryption tools are stored on external servers that can be accessed only by them. Asa  result, victim's files become unreachable for anyone except the cybercriminals. This is the main reason, why data recovery is so hard to carry out without having backups of the important files.^[1].
