Bgjs Virus Removal Guide (+Decrypt .bgjs files)

Bgjs – Ransomware

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

Bgjs was created for the sole function to encrypt all popular file types. Realistically, as quickly as the file encryption is successfully achieved, the users are unable to get access to them. Bgjs ransomware includes its own “.bgjs” to all the encrypted files. For instance, the file “price_list.xls”, when modified by Bgjs, will be titled as “price_list.xls.bgjs”. When the file encryption is achieved, Bgjs puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.

The alert stated by document asking for the random os extremely comparable to the notices provided by other ransomware dangers coming from the DJVU family. The caution essentially shows that the files have been secured and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is definitely true.

The approach to secure the files used by Bgjs is not totally looked into. However, there is no doubt that each computer system owner might be released an unique decryption key, which is definitely distinct. It is exceptionally hard to recover the data without the proper type 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 Bgjs 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 scoundrels who have introduced the Bgjs infection into the internet. In order to get the key and bring back the crucial data, the users are told to connect with the frauds by means of email or by telegram and to pay the ransom in the amount of $980.

The message also states that the people must get in touch with the Bgjs authors within 72 hours upon the moment of the data file encryption. The alert suggests that by doing so the people will acquire a 50% discount, therefore, the ransom amount drops down 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 crooks will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is gotten into their accounts. Hence, paying ransom frequently does not lead to a successful healing. So, the users may just lose their money for nothing.

Likewise, we advise you not to contact the frauds as they advise. Do not transfer loan into their wallets. There are no applications that could break the Bgjs virus or restore the data at no charge. For that reason, the only correct decision is to restore the information from possible backups (if offered).
