The caution generally indicates that the information has been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.
The technique to encrypt the files used by Qore is not totally researched. Nevertheless, there is no doubt that each computer system owner might be released a special decryption key, which is absolutely unique. It is very hard to recuperate the information without the appropriate key in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Qore infection is that the users are not able to get access to the key.
