Pykw was developed for the sole function to encrypt all popular file types. Logically, as quickly as the file encryption is effectively achieved, the users are unable to get access to them. Pykw ransomware adds its own “.pykw” to all the encrypted data. For instance, the file “price_list.xls”, when crypted by Pykw, will be entitled as “price_list.xls.pykw”. Once the file encryption is achieved, Pykw puts its own distinct text document (_readme.txt) into all the folders that store the encrypted files.

The alert mentioned by document requesting the random os really similar to the notifications given by other ransomware risks belonging to the DJVU family. The warning essentially shows that the files have been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is absolutely true.
