Vyia Virus Removal Guide (+Decrypt .vyia files)

Vyia – General Info

Vyia is a malicious software application working as common ransomware. Michael Gillespie, the popular malware researcher, very first found this new name in the DJVU ransomware family.

Vyia was created for the sole function to encrypt all popular file types. Logically, as soon as the encryption is successfully accomplished, the users are unable to get access to them. Vyia ransomware adds its own “.vyia” to all the encrypted data. For instance, the file “price_list.xls”, once crypted by Vyia, will be entitled as “price_list.xls.vyia”. Once the file encryption is achieved, Vyia puts its own distinct text document (_readme.txt) into all the folders that store the encrypted files.

The alert specified by text file requesting the random os extremely comparable to the alerts provided by other ransomware dangers coming from the DJVU family. The caution essentially indicates that the files have been encrypted and the only service to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.

The method to encrypt the files used by Vyia is not entirely researched. However, there is no doubt that each computer owner might be provided a special decryption key, which is definitely distinct. It is incredibly difficult to recuperate the data without the proper key in location.

“Don’t worry, you can return all your files!”, from _readme.txt message:

Don't worry, you can return all your files! virus

One more peculiarity of the Vyia virus is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the total control by the criminals who have actually launched the Vyia ransomware into the web. In order to get the key and restore the crucial data, the users are told to connect with the frauds via e-mail or by telegram and to pay the ransom in the quantity of $980.

The message also states that the people ought to contact the Vyia authors within 72 hours upon the minute of the data encryption. The alert shows that by doing so the people will get a 50% discount rate, therefore, the ransom quantity falls to $490.

No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no guarantee that these online crooks will keep their promises, so they may not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Thus, paying ransom frequently does not lead to a successful healing. So, the users may just lose their money for nothing.

Similarly, we prompt you not to call the scams as they instruct. Do not transfer money into their wallets. There are no applications that could break the Vyia virus or restore the data for free. Therefore, the only proper choice is to bring back the data from possible backups (if available).
