Aamv is a harmful software working as common ransomware. Michael Gillespie, the popular malware researcher, first found this new name in the DJVU ransomware family.

Aamv was developed for the sole purpose to encrypt all popular file types. Realistically, as quickly as the encryption is successfully accomplished, the users are unable to get access to them. Aamv ransomware adds its own “.aamv” to all the encrypted files. For example, the file “price_list.xls”, once crypted by Aamv, will be entitled as “price_list.xls.aamv”. As soon as the file encryption is accomplished, Aamv puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The alert stated by _readme.txt requesting the random os really comparable to the notices offered by other ransomware threats belonging to the DJVU family. The warning generally shows that the data has been encrypted and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.
