The warning essentially indicates that the information has been secured and the only solution to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely true.

“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Yytw infection is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the total control by the scoundrels who have introduced the Yytw ransomware into the internet. In order to acquire the key and restore the important information, the users are informed to contact the frauds by means of e-mail or by telegram and to pay the ransom in the amount of $980.
