One of the latest versions of notorious ransomware called Locky appends the files with .aesir file extension. It utilizes RSA-2048 and AES-256 encryption methods for the encoding process. Since the latter techniques are based on a public and private key combination, the decryption without the respective key remains a complicated matter. However, while IT specialist are working on the decryption tools, security applications devised alternative methods for decrypting the files. Do not consider transmitting the money as the chances of receiving the data are very low. As you may know, Locky virus has made hundreds of billions of profit by infecting corporations, hospitals, and corporate users. That is why do not foster any hopes and remove Aesir ransomware with a security tool. You may use Reimage for that purpose. Below find some of the suggestions to recover the files.
