Msjd is a cyber virus known as Ransomware that will lock up important files on your PC and demand a ransom to release them. Msjd uses high-level encryption to render your data inaccessible and the key to decrypt the files is held by the hackers.

The Msjd virus file ransom note

The Ransomware viruses are notorious for their ability to place the user’s data under a lockdown and to then demand that a ransom is paid from the user if the latter wishes to be able to open any of their files again. This is currently one of the most common forms of criminal online money extortion and it is also one of the most effective ones. As it turns out, most users do not have proper backups for their files and once all their important data stored on their computers gets encrypted by a scary Ransomware infection the only seemingly viable option is to pay the money that the criminals want – a necessary evil in order to make the locked data accessible again. However, is this really a viable option, and could paying the ransom bring your files back. Well, the truth is that there couldn’t be a certain answer to this question and the reason is simple: you cannot trust the hackers. It doesn’t matter how convincing they may seem in their promises to send you a decryption key for the files that their virus has locked-up, you simply cannot trust such promises.

The Msjd virus

The Msjd virus is a piece of malware that is used as a blackmailing tool that will deny you access to your most important files unless you perform a ransom payment. The hackers behind the Msjd virus want your money and they will not release your data until you pay.

Sending your money to them might sometimes get you your files back. However, what’s the guarantee there that this is exactly how things would go in your particular case. It’s possible that this time the criminals decide that they won’t cooperate and that they’d leave you without a way to open your files. It is also possible that the hackers do not actually have a working decryption key and they are simply trying to deceive you in order to get your money, without really having the intention to help you. And, of course, if you do pay them, it is irrelevant whether or not you receive the decryption key for the files as far as your money is concerned. That money is gone the moment you send it to the hackers and there is no way of getting it back. In fact, in most cases, the ransom that the hackers demand is supposed to be paid in BitCoin or another similar currency, which, in turn, makes it next to impossible to trace the transaction. This is how hackers who use Ransomware are able to stay anonymous and it is also why they are rarely brought to justice.

The Msjd file encryption

The Msjd file encryption is the process that enables this virus to make each file it targets totally inaccessible. The Msjd file encryption is unbreakable and only a special key that the hackers hold can reverse it.

The best course of action according to most security experts is to first remove the virus and then try some alternative ways to retrieve at least some of your data. A guide added down below will help you remove Msjd and a special section attached to it will give you advice regarding the alternatives you can try in order to restore some files from the grasp of Msjd, YgvbDwqs or Nuhb. However, remember that you must make sure that Msjd is no longer in your computer before you try to recover any of your data or else anything you manage to bring back may get encrypted again.

Check the Processes tab of Task Manager for any suspicious processes by pressing CTRL+SHIFT+ESC on your keyboard. Those processes that don’t appear to be linked to any of your regular programs, as well as those that consume a lot of CPU and RAM resources without any apparent reason, should be given extra attention. When you notice a suspicious process running, right-click on it and choose Open File Location from the context menu that appears on the screen.


It’s possible to scan suspicious-looking process files for malware using the free online virus scanners listed below. The content of the suspected process’s File Location folder can be dragged and dropped into the scanner to be scanned.

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    When the scan is complete, delete any files that were flagged as potentially harmful. Some files cannot be deleted while the suspicious process is running, so end it first by right-clicking the suspicious process and selecting End Process from the quick menu.


    Windows’ search bar can be used to search for the command msconfig, which will open the System Configuration window. Msjd-related startup items can be found in the Startup tab.


    If you’re going to leave the checkboxes on startup items, it’s best to do so only for legitimate ones. Uncheck all startup items that have an “unknown” manufacturer or a random name.

    The Hosts file is another location on a compromised computer where malicious changes can be made without your permission. One way to check for suspicious IP addresses is to open the file and check what is added under  “Localhost” in the text. It is possible to do this quickly and easily using Win key and R key combination and then pasting the following line in the Run box:

    notepad %windir%/system32/Drivers/etc/hosts

    Press Enter to run the command and let us know if you notice any suspicious IP addresses in the file under Localhost, as shown in the image below. These IPs will be investigated by a member of our team to see if they pose a threat.

    Malware programs are becoming increasingly adept at evading anti-malware programs by inserting harmful registry entries into the system. As a result, we recommend using the Registry Editor to see if any harmful files have been added to your registry. There are a variety of ways to do this. Type Regedit into the Windows search bar and hit Enter. To bring up the Find window in the Registry Editor, hold down CTRL while pressing F. In the Find box, type the name of the ransomware that has infected your computer and click on Find Next to begin the search for ransomware-related files.

    Remove ransomware-related search results from the results page. The registry can be searched again to see if there are any other files with the same name after the first result has been found and removed.

    Attention! In the process of clearing the registry, you may happen to delete files unrelated to the ransomware infection and this may cause damage to the operating system. On the other hand, it is possible that the ransomware will reappear if you do not remove all registry entries associated with the threat. For this reason, we recommend that you use a professional anti-virus software to clean your computer of malware and dangerous registry files.

    It’s also a good idea to inspect the following locations manually. Open one at a time by typing each exactly as it is shown below, including the % symbol, in the Windows search bar and pressing Enter.

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

    Any suspicious-looking files recently added to these locations should be deleted. Select the files in your Temp folder and press Del on your keyboard to delete all of your system’s temporary files.


    How to Decrypt Msjd files

    Those who have had the ransomware removed are still faced with the challenge of decrypting their encrypted files. In addition, the methods used to decrypt the data that the ransomware encrypts may vary depending on the variant of malware that has infected you. Look at the file extensions to identify the ransomware variant you are dealing with.

    Before any file recovery attempts are made, the infected system should be scanned with a reputable anti-virus program (like the one on this page). A virus-free and ransomware-free computer can be used to test various file recovery methods and even connect backup sources to it.

    New Djvu Ransomware

    Cybersecurity experts have recently discovered a new Djvu ransomware variant which is named STOP Djvu. The encoding used by this infection is unique compared to other types of malware because of its .Msjd extension at the end of each encrypted file. Offline key decryptors, such as the one available at this link, may be used to decrypt data that has been encrypted by this threat.

    Open the STOPDjvu.exe file you downloaded from the link above by clicking “Run as Administrator” and then clicking on Yes. You can begin decrypting data after reading the license agreement and any accompanying brief instructions. Files encrypted with unknown offline keys or online encryption cannot be decrypted by this tool, so please be aware of that.

    If you find yourself in trouble, please use the anti-virus software on this page to quickly and easily remove the ransomware. You can also use a free online virus scanner to check your computer for any suspicious files.
