Vvyu Virus Removal Guide (+Decrypt .vvyu files)

Vvyu – Ransomware

Vvyu is a harmful software application functioning as typical ransomware. Michael Gillespie, the popular malware researcher, first found this new name in the DJVU ransomware family.

Vvyu was created for the sole function to encrypt all popular file types. Realistically, as soon as the encryption is effectively achieved, the users are unable to get access to them. Vvyu virus adds its own “.vvyu” to all the encrypted files. For example, the file “price_list.xls”, as soon as modified by Vvyu, will be titled as “price_list.xls.vvyu”. As soon as the file encryption is achieved, Vvyu puts its own distinct text file (_readme.txt) into all the folders that store the encrypted files.

The alert mentioned by document requesting the random os very comparable to the notices given by other ransomware threats coming from the DJVU family. The caution basically shows that the information has been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely real.

The method to encrypt the files utilized by Vvyu is not totally researched. Nevertheless, there is no doubt that each computer system owner might be issued a special decryption key, which is definitely special. It is extremely difficult 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 Vvyu 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 total control by the crooks who have actually released the Vvyu ransomware into the internet. In order to get the key and bring back the essential data, the users are told to get in touch with the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.

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

No matter what the amount of the ransom is, we strongly recommend that you do not pay the ransom. There is no warranty that these online criminals will keep their guarantees, so they may not care at all what the victims feel about the encryption, even when the amount of the ransom is gotten into their accounts. Thus, paying ransom typically does not lead to an effective healing. So, the users might just lose their money for nothing.

Likewise, we advise you not to get in touch with the frauds as they advise. Do not move loan into their wallets. There are no applications that could crack the Vvyu virus or restore the information at no cost. For that reason, the only appropriate choice is to bring back the data from possible backups (if readily available).
