Zfdv is a harmful computer program that attacks computers with the goal to blackmail their owners by taking some of their valuable data hostage. Zfdv doesn’t restore access to the files of its victims until the latter send a ransom payment to the blackmailer’s virtual purse.

This type of threat is one of the most commonly encountered categories of viruses. The umbrella term that is used to refer to a virus of this category is Ransomware. Ransomware infections like ZppsQlln mostly infect Windows computers, but, though unlikely, there could be some versions that may infect Macs or other devices with other operating systems. In the current article, our focus will be the newly-released Zfdv. Once on the PC, this malicious program will silently initiate a process of encryption that will render all targeted data files unavailable. In other words, upon the completion of the encryption process, you won’t be able to open any of the files that have been affected by this virus.

The encryption used by this Ransomware is a very potent tool for locking data. It cannot be reverted through regular means and the only surefire method of unlocking the files is through the implementation of a special key that is unique for every infected computer. The key is generated on the hackers’ servers during the encryption process so that only they have access to it. Naturally, the criminals’ goal is to get you to pay them for that key because it is the only thing that can set your files free (at least according to the hackers behind the virus).

The Zfdv virus

The Zfdv virus is a malware variant of the Ransomware family and its main ability is to lock the files you have saved on your PC’s hard drives. The method the Zfdv virus uses to achieve this is known as file encryption.

The unpleasant truth when talking about Ransomware is that nothing can guarantee that you’d eventually get the decryption key and release your files with it. Paying the ransom is, therefore, not a very good option, as it could lead to money loss without the restoration of the encrypted data. After all, the hackers behind the malware are criminals that are not to be trusted.

Unfortunately, though, there are other methods that can be applied in an attempt to recover some data, the effectiveness of said methods is likely to vary from one instance to the other. Still, the best advice we could give you here is to try every alternative option before you actually consider paying the ransom.

The .Zfdv file decryption

The .Zfdv file decryption is an action that unlocks the files encrypted by this virus and can be executed with the help of a decryption key. The .Zfdv file decryption, however, may not be the only way to recover files encrypted by this virus.

To try the alternatives suggested on our site, you will first need to remove the virus and the removal steps below will help you with that. Follow them exactly as they are shown and you should be able to rid your PC of the malicious Zfdv Ransomware.

Remove Zfdv Ransomware


To start off, add this page to your bookmarks. This will save you from wasting time searching for the Zfdv removal instructions every time you need to restart your computer during some of the steps below.

In addition, it is recommended that you restart your computer in Safe Mode by following the instructions provided in the link before proceeding to the next step. When you restart the operating system in Safe Mode, only the most important programs and apps will be allowed to operate, making it much easier to identify anything that is behaving abnormally.

Then, you may access the Task Manager by typing CTRL+SHIFT+ESC on your keyboard. After it has been launched, go to the Processes tab to check for any suspicious-looking processes that may be running on your computer. If any of these processes seem to be using an excessively high amount of CPU and RAM resources for no apparent reason, right-click on each one and choose Open File Location from the context menu. This will allow you to see the related files for the selected process.


Utilize the below-provided free online virus scanner to search for harmful code inside the files associated with the suspicious-looking process. Simply drag and drop the contents of the File Location folder of the suspicious process into the scanner box to begin the scanning process.

    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.

    After the scanning process is complete, you will need to remove any files that have been recognized as potentially hazardous. Before removing the files, however, it is essential to end the suspicious process that is running. To do this, right-click the process in the Task Manager and select End Process from the quick menu.


    As a third step in this guide, type msconfig in the Windows search bar and then press the Enter key to launch the System Configuration window. Open the “Startup” tab to see whether it contains any Zfdv-related startup items.


    If needed, conduct an internet research and in case that you collect sufficient evidence that some of the startup items may be associated with the ransomware, you should disable them by removing the checkmark from the checkbox next to their names.

    The next step that you should not skip is to access the Hosts file and check it for any modifications. This is accomplished by simultaneously pressing the Win and R keys, and then pasting the following code in the Run box:

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

    After choosing the OK button to open the file, search the file’s content for the term “Localhost.” Please indicate in the comments any IP addresses that seem to be unsafe, as shown in the image below. This will enable us to investigate the matter further and get back to you with any further instructions.

    As a fourth step of this guide, we will show you how to start the Registry Editor, look for potentially dangerous files associated with the ransomware, and then delete those items from the registry. This is one of the most critical steps you must do if you want to totally remove Zfdv from your computer. 

    You can open the Registry Editor by navigating to the Windows search bar, entering “Regedit“, and then hitting the “Enter” key on your keyboard. When you start the Registry Editor, simultaneously press and hold the Ctrl and F keys to open a Find box on the screen. You will need to enter the name of the ransomware in the Find box and then click the Find Next button to begin looking for files and folders that are associated with the infection.

    It is vital to use extreme caution while eliminating search results associated with the ransomware, since the registry may include other files connected to the danger. Therefore, after deleting the files detected in the first search results, you should do a second search to guarantee that no additional files with the same name exist. If no more files with the same name are located, the danger has been removed.

    Attention! Use extreme caution before deleting any registry files from your computer that are associated with ransomware in order to avoid the operating system and any installed applications from being damaged. Keep in mind that the ransomware may reappear on your machine if you fail to remove all registry entries associated with the threat. For this reason, it is strongly recommended that you use an anti-virus program to check your computer and delete any potentially harmful software or registry entries that may have been placed on it.

    In addition, we recommend that you inspect the following five system locations to verify that they do not contain potentially harmful files and folders. This may be accomplished by entering each item in the Windows search bar and hitting the Enter key.

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

    Perform a thorough inspection of the contents of each of these directories, and then remove any suspicious files that may have been added recently. Additionally, you may want to erase all files in the Temp folder on your computer. To do this, select the files and then press the Delete key on the keyboard.


    How to Decrypt Zfdv files

    The first step in decrypting any data that may have been encrypted as a result of the Zfdv attack is to eliminate any ransomware that may have been present on the infected computer system. Therefore, do not skip the preceding four steps of the removal guide and ensure that Zfdv has been eliminated successfully. After you have cleared all traces of viruses and ransomware from your computer, the next step is to investigate the various file recovery methods available to you.

    Several ways exist for decrypting ransomware-encrypted data when it comes to file recovery. However, the technique used to decrypt the data may vary depending on the ransomware variant that has infected your machine. If you examine the file extensions that are being appended to the end of encrypted files, you will be able to determine the exact variant of ransomware that you are dealing with.

    New Djvu Ransomware

    STOP Djvu ransomware, a new member of the Djvu ransomware family, has lately drawn the attention of security professionals due to its global attacks. This ransomware version targets several file types, encrypts them, and then appends an extension .Zfdv at the end of each. The good news is that, in some situations, it may be possible to restore access to the encrypted data. We suggest using an offline key decryptor, such as the one in the URL below, to decrypt any data that has been encrypted by the Zfdv ransomware. 


    To do this, visit the URL above and download the STOPDjvu.exe program. Next, choose “Run as Administrator”. When asked, click “Yes” in the confirmation window that appears. After reading the license agreement and any other brief instructions contained with it, you may begin the decryption procedure. Please be aware that this program may be unable to decode files encrypted using an unknown offline key or online encryption.

    If you have issues while completing any of the steps in this removal guide, or if you are unable to manually remove Zfdv, you should remove the ransomware using the anti-virus software that is linked to on this page. You should also manually search your computer for possibly harmful files using the free online virus scanner that we have linked for you. If you have any questions, don’t hesitate to share them with us, and we will do our best to reply you shortly.
