The caution basically indicates that the files have been encrypted and the only solution to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely real.
The technique to secure the files used by Tgvv is not entirely looked into. Nevertheless, there is no doubt that each computer system owner may be released an unique decryption key, which is definitely distinct. It is extremely hard to recover the information without the proper type in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Tgvv ransomware is that the users are unable to get access to the key.
