Remove BGJS Ransomware Virus (+DECRYPT .bgjs Files)

Bgjs malware is a sort of computer virus that infiltrates your PC, encrypts your documents, and then asks to pay the ransom for file decryption. Besides these unwanted activities, that virus also changes some important settings and can even stop your antivirus program.

Bgjs virus – what is it?

Bgjs ransomware can correctly be described as a STOP/Djvu ransomware family. That type of malware is aimed on single users. This specification supposes that Bgjs does not carry any sort of additional malware, which sometimes helps virus of other families to control your computer. Since most users do not have anything valuable on their PCs, there is no need to carry additional malware that increases the risk of failure of the whole ransomware operation.

The typical signs of that ransomware activity is the emersion of .bgjs files in your folders, instead of the document you used to have. The photo.jpg turns into photo.jpg.bgjs, report.xlsx – into report.xlsx.bgjs and so on. You cannot to prevent this action, as well as can’t open that documents – they are ciphered with pretty strong algorithm.

You can also see different other signs of malware activity. Suddenly suspended Microsoft Defender and inability to open the popular anti-malware forums or websites, where the virus removal and decryption guides are posted. You will see how it works in the paragraph below. The removal and decryption guide are also available – check below how to remove Bgjs malware and get the .bgjs files back.

How did Bgjs ransomware encrypt my files?

After the injection, the Bgjs ransomware creates a connection with its command and control server. This server is controlled by virus maintainers – people who manage the distribution of this ransomware. Another activity which is conducted by these crooks is answering the email messages of victims, who intend to decrypt their files.

The files are encrypted with one of the strongest encryption algorithm – AES-256. The digit in the name of this algorithms means the power of two – 2^256 for this case. 78-digit number of possible password variations – it is impossible to brute force it. As analysts say, it will need more time than our planet can estimate to exist, even if you use the most powerful computer system. In each folder that has the encrypted documents, Bgjs virus leaves the _readme.txt file with the following contents:

ATTENTION!

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

Nonetheless, you can still use some of your files. The Bgjs virus encrypts only the first 150 KB of each file, but the other piece of this document can be opened. Primarily, it works best with audio/video files, which are surely bigger than 150 kilobytes. Not each media player is able to open these files – WinAmp is the best choice, since it is free and well-tested. First seconds of every song or video will be missing – this part is encrypted – but the rest of the file will be accessible like nothing happened.

Is Bgjs ransomware dangerous for my PC?

As it was described several paragraphs above, ransomware is not only about encrypting the files. Bgjs ransomware makes the changes in your operating system in order to prevent looking for the malware removal and file decryption guides. Malware does not establish the software barrier – it just modifies the settings, primarily – networking and security configurations.

Through the networking settings, the most changed item is the HOSTS configuration file. This text file has the DNS-address instructions, which are used by the web browsers while sending a request to the server. If you add a specific DNS-address for the certain website, your browser will connect that site through this DNS next time. Ransomware alters that file, adding the unknown DNS, so any of the web browsers will show you the “Unable to resolve the DNS-address” error.

Other changes done by the virus are aimed at prevention of fast detection of itself, and also blocking the installation of the majority of antivirus programs. Bgjs ransomware makes some modifications in Group Policies – the system setting interface which allows to alter the rights of each app. In such a way, ransomware disables the Microsoft Defender and various other antivirus tools, as well as disables the launch of anti-malware installation files.

How did I get infected?

Throughout the whole term while STOP/Djvu family existed, it was using dubious software as the main way of ransomware injection. Under the term of dubious programs I mean applications that are already not supported by the developer and spread through the third-party websites. These apps may be cracked, to make them possible to use without purchasing any license. Another example of such a program type is various hacking tools – cheat engines, keygens, Windows activation tools and so on.

This sort of apps may be distributed in different methods – through the web page that offers a downloading link, as well as through the peering networks – ThePirateBay, eMule and so on. All these sources are well-known as the most popular computer piracy resources. Folks use these sites to get various apps or games for free, even if these programs must be purchased. Nobody can stop the users who hack these apps from adding malware of some sort to the files of the hacked tool. Hacktools, meanwhile, are created for outlaw targets, so their creators can easily add the ransomware under the guise of some program part.

These cracked programs, regardless of their source, are one of the most often sources for various malware, and 100% the most widespread one for Bgjs virus. The best solution is to stop making use of it, and not only because of virus spreading risks. Avoiding the license purchase is an illegal action, and both hackers and folks who make use of cracked programs fall under the charge of piracy.

How do I remove Bgjs virus?

The Bgjs virus is really hard to wipe out manually. In fact, because of the number of alterations it makes into your system, it is almost impossible to spot them all and repair. The best option is to use anti-malware programs. But which one to choose?

You may see the offers to use Microsoft Defender, that is already inside of your system. However, as it was mentioned earlier, most of STOP/Djvu malware examples block it even before the ciphering process. Making use of the third-party program is the only possible option – and I can offer you the GridinSoft Anti-Malware as a solution for that case. It has perfect detection abilities, so the virus will not be missed. It is also capable of system repairing, which is heavily needed after the Bgjs virus attack.

To remove Bgjs malware infections, scan your computer with legitimate antivirus software.

After the ransomware removal, you can go to file decryption. Virus removal is needed to prevent the repeating encryption of your files: while Bgjs ransomware is active, it will not miss any unencrypted file.

How to decrypt the .bgjs files?

There are two ways to decrypt your files after a Bgjs malware attack. First one and the most obvious is file decryption. It is performed with a special app, designed by Emsisoft, and named Emsisoft Decryptor for STOP/Djvu. This program is absolutely free. Analysts update its decryption keys databases as often as possible, so you will definitely get your files back, sooner or later.

Another way to get your documents and photos back is to try to recover them from your physical disks. Since Bgjs virus deletes them and substitutes with an encrypted copy, the residue of the documents are still kept on the disk. After the deletion, the information about them is wiped from the file system, but not from a disk drive. Special tools, like PhotoRec, are able to recover these files. It is free, too, and may also be used for file recovery in case when you have deleted a thing unintentionally.

Decrypting the .bgjs files with Emsisoft Decrypter for STOP/Djvu

Download and install Emsisoft Decrypter tool. Agree with its EULA and continue to the interface.

The interface of this program is extremely easy. All you have to do is to select the folder where the encrypted files are stored, and wait. If the program has the decryption key which corresponds to your ransomware case – it will decrypt it.

During the use of Emsisoft Decrypter for STOP/Djvu, you may observe various error messages. Don’t worry, that does not mean that you did something wrong or a program does not work properly. Each of these errors refer to a specific case. Here is the explanation:

Error: Unable to decrypt file with ID: [your ID]

The program does not have a corresponding key for your case. You need to wait for some time until the key database will be updated.

No key for new variant online ID: [your ID]

Notice: this ID appears to be an online ID, decryption is impossible.

This error means that your files are encrypted with an online key. In such a case, the decryption key is unique and stored on the remote server, controlled by crooks. Unfortunately, the decryption is impossible.

Result: No key for new variant offline ID: [example ID]

This ID appears to be an offline ID. Decryption may be possible in the future.

Ransomware uses the offline key to encrypt your files. This key is not unique, so you likely have it in common with another victim. Since offline keys must be collected, too, it is important to keep calm and wait until the analysts team finds one which will fit your case.

Remote name could not be resolved

This error indicates that the program has problems with DNS on your computer. That’s a clear sign of malicious alterations in your HOSTS file. Reset it using the official Microsoft guide.

Recovering the .bgjs files with PhotoRec tool

PhotoRec is an open-source tool, which is designed to recover the deleted or lost files from the disk. It checks each disk sector for the residues of deleted files, and then attempts to recover them. That app is able to recover the files of more than 400 different formats. Because of the described feature of ransomware encryption mechanism, it is possible to use this tool to get the original, unencrypted files back.

Download PhotoRec from the official website. It is absolutely free, however, its developer warns that he does not guarantee that this program will be 100% effective for file recovery purposes. Moreover, even paid apps can barely give you such a guarantee, because of the chain of random factors that can make the file recovery harder.

Unzip the downloaded archive to the folder you like. Don’t worry because of its name – TestDisk – this is the name of the utility developed by the same company. They decided to spread it together since PhotoRec and TestDisk are often used together. Among the unzipped files, search for qphotorec_win.exe file. Run this executable file.

Before you can start the recovery process, you need to specify several settings. In the drop-down list, choose the logic disk where the files were stored before the encryption.

Then, you need to specify the file formats you need to recover. It may be difficult to scroll all 400+ formats, luckily, they are sorted by alphabetical order.

Finally, name the folder you want to use as a container for recovered files. The program will likely dig out a lot of useless files, which were deleted intentionally, so desktop is a bad solution. The best option is to use the USB-drive.

After these easy manipulations, you may just press the “Search” button (it turns active if you specified all required parameters). The recovery process may take several hours, so keep patient. It is recommended not to use the computer during this term, since you may overwrite some files you are intending to recover.
