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

“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Uihj virus is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the criminals who have actually launched the Uihj virus into the web. In order to get the key and bring back the important data, the users are informed to get in touch with the frauds via email or by telegram and to pay the ransom in the amount of $980.
The message likewise states that the people need to get in touch with the Uihj authors within 72 hours upon the minute of the data file encryption. The alert shows that by doing so individuals will obtain a 50% discount, therefore, the ransom quantity drops down to $490.
