Zfdv was created for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is effectively achieved, the users are not able to get access to them. Zfdv virus adds its own “.zfdv” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Zfdv, will be titled as “price_list.xls.zfdv”. When the encryption is achieved, Zfdv puts its own special text file (_readme.txt) into all the folders that save the encrypted files.
The alert mentioned by document requesting for the random os extremely similar to the alerts provided by other ransomware dangers belonging to the DJVU family. The warning generally indicates that the files have been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely real.
The method to encrypt the files used by Zfdv is not completely investigated. However, there is no doubt that each computer owner may be issued a special decryption key, which is definitely special. It is extremely difficult to recover the information without the suitable key in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Zfdv ransomware is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have actually released the Zfdv ransomware into the world wide web. In order to obtain the key and restore the crucial information, the users are told to contact the scams by means of email or by telegram and to pay the ransom in the amount of $980.
