Zdfv is a dangerous virus that attacks the files stored on Windows computers with the goal to lock them up. The Zdfv lockdown of the files is made possible through the implementation of a process known as data encryption.

The Zdfv ransomware will leave a _readme.txt file with instructions

The encryption applied to the files ensures that no conventional software can open or use them, leaving the user with no way of accessing their own files. The idea behind all this isn’t to necessarily rob the victims of their personal files but to make them pay ransom for the release of the locked data. In most cases, once the virus has finished its job, it automatically places a message on the user’s screen, in which message there is a ransom demand. It is explained to the user that their files can only be accessed through the application of a special key that the hackers possess. This key would (supposedly) be sent to the victim if the latter completes the demanded ransom payment. Oftentimes there are even instructions on how to transact the required sum and how to obtain the currency in which the money is demanded (for example, how to buy Bitcoins, if that is the currency specified by the hackers).

The Zdfv virus

The Zdfv virus is a blackmailing malware tool that is used by its criminal creators to lock the files of their victims and ask for a ransom payment. The Zdfv virus falls under the Ransomware virus category and it typically spreads via Trojan horse backdoors.

The Zdfv virus will encrypt your files

If you have fallen victim to this nefarious piece of malware and if the files that it has managed to encrypt are of high value to you, then you are probably wondering if paying the ransom will solve your problems, albeit at a certain material price. The truth is that we cannot give a definitive answer to this question but we can warn you about the potential consequences of choosing this course of action, namely, the fact that you may still not regain access to your data even after paying. The hackers are, after all, criminals and there’s no reason to trust anything they say, including that they would send you a decryption solution. It is, therefore, much better to try to solve this problem yourself, by firstly removing the virus and then trying some alternative options regarding the recovery of your data.

The Zdfv file extension

The Zdfv file extension is a short sequence of letters that the virus appends to the end of your files’ names, replacing their regular extensions. The Zdfv file extension doesn’t match any existing file format and is therefore unrecognizable to conventional software.

This is partially what keeps your files unavailable but removing this extension manually won’t do anything – your files will still remain locked. One option here is to retrieve the decryption key but as we already mentioned this may not be possible no matter what you do. However, there may be some other options that you will find in our removal guide. Just remember to first go through the removal steps so that the virus is eliminated and prevented from encrypting any more of your data.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

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.

    After you open their folder, end the processes that are infected, then delete their folders. 

    Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.



    Hold the Start Key and R –  copy + paste the following and click OK:

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

    A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    hosts_opt (1)


    If there are suspicious IPs below “Localhost” – write to us in the comments.

    Type msconfig in the search field and hit enter. A window will pop-up:



    Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

    • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.


    Type Regedit in the windows search field and press EnterOnce inside, press CTRL and F together and type the virus’s Name. 

    Search for the ransomware  in your registries and delete the entries. Be extremely careful –  you can damage your system if you delete entries not related to the ransomware.

    Type each of the following in the Windows Search Field:

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

    Delete everything in Temp. The rest just check out for anything recently added. Remember to leave us a comment if you run into any trouble!
