Bbyy Virus Removal Guide (+Decrypt .bbyy files)

Bbyy – General Info

Bbyy is a destructive software application working as common ransomware. Michael Gillespie, the well-known virus researcher, first found this new name in the DJVU ransomware family.

Bbyy was developed for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is effectively achieved, the users are unable to get access to them. Bbyy ransomware adds its own “.bbyy” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Bbyy, will be titled as “price_list.xls.bbyy”. When the encryption is accomplished, Bbyy puts its own special text file (_readme.txt) into all the folders that store the encrypted files.

The alert mentioned by _readme.txt requesting for the random os extremely similar to the notifications provided by other ransomware risks belonging to the DJVU family. The caution basically shows that the information has been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely real.

The method to secure the files used by Bbyy is not completely looked into. Nevertheless, there is no doubt that each computer owner might be provided an unique decryption key, which is absolutely special. It is incredibly difficult to recuperate the data without the appropriate key in location.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Bbyy infection 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 scoundrels who have actually introduced the Bbyy infection into the internet. In order to acquire the key and restore the important data, the users are informed to contact the frauds through e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise says that individuals need to call the Bbyy authors within 72 hours upon the moment of the data file encryption. The alert indicates that by doing so individuals will obtain a 50% discount rate, for that reason, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we highly encourage that you do not pay the ransom. There is no assurance that these online scoundrels will keep their guarantees, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom often does not lead to a successful healing. So, the users may simply lose their money for absolutely nothing.

Likewise, we urge you not to call the frauds as they advise. Do not transfer money into their wallets. There are no applications that could split the Bbyy ransomware or bring back the data at no charge. Therefore, the only correct decision is to restore the information from possible backups (if available).
