Dazx is a Ransomware infection that abuses its victims by taking hostage of files that are of great value to them. In return for providing means to liberate the target files, Dazx demands a ransom payment and displays a money-requesting notification on the infected computers’ screen.

Ransomware is a popular type of malware that is used to abuse web users through blackmail. A major problem with such threats is that it is easy for the malware to sneak unnoticed inside the device and encrypt all the data that is stored there without being detected. This is because most Ransomware infections, including Dazx, QapoErop will typically not trigger any visible symptoms of their presence during the attack. Moreover, the method used to keep the user information inaccessible is known as data encryption, and once the information is encrypted by the malware, it becomes virtually impossible to access it without applying a uniquely generated decryption key.

The hackers behind Dazx focus on offering the victims to purchase that decryption key from them for a fixed amount of money. They typically display a ransom notification on the screen of the infected machines with instructions about how to transfer the required money in order to obtain the corresponding key for their files.

Many individuals who can’t afford to lose access to important data give in to the blackmail scheme and send the ransom money to the crooks. But, sadly, not all users who make the ransom payment manage to regain access to their encrypted files. There are many instances where the people get nothing in return for their money and are left with inaccessible bits of data and empty pockets. This is yet another critical thing when it comes to facing Ransomware infections like Dazx – there is never an assurance that you will access your data again, even after you fulfill the demands of the hackers behind the infection.

The Dazx virus

The Dazx virus is a piece of malware that can cause significant data loss by restricting user access to it. The Dazx virus normally encrypts files that are most frequently used and displays a notice on the screen, where a ransom payment is required to regain access to them.

Users who do not want to put their hard-earned money at risk by giving it to the offenders,  however, are advised to explore other options to deal with the encryption and remove Dazx.

Of course, we need to note that none of the alternatives can give guarantees as to how the data will be retrieved and how many files will become accessible again. Still, doing some extensive research and choosing legitimate ransomware recovery options (such as those listed in the file-recovery section below) is much more advisable than transferring money to anonymous hackers and hoping that one day they will send you a special decryption key.

The Dazx file recovery

The Dazx file recovery is a way for the users to regain access to their encrypted information. Fortunately, there are some free methods for Dazx file recovery such as using a personal backup or shadow copy restore process.

There are other solutions online, and while they might not all work, most of them may still be worth the try, especially if you don’t have to contact hackers or transfer money to them. However, in order to have better chances to recover anything, make sure you first remove Dazx with the instructions in the guide that follows.

    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 Enter. Once 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!



    How to Decrypt Dazx files

    Decrypting data encrypted by ransomware is one of the most challenging tasks, and there is no universal solution for it. Therefore, you may need to use a combination of techniques to get some of your files back. You’ll need to decide which of the available file-recovery options will be most effective depending on the variant of ransomware that has attacked your machine. The quickest way to identify the specific variant of ransomware that has infiltrated your system is to check the file extensions of the encrypted files.

    New Djvu Ransomware

    The latest Djvu ransomware variant, known as STOP Djvu, is easily identifiable thanks to the .Dazx extension appended to the victims’ encrypted files. As of this writing, it is possible to decode files encrypted with this version if they were encrypted with an offline key. If you need assistance decrypting files, try the application at the following link:

    Decryption tool

    If you click the Download button at the top of the page, you’ll be able to save the STOPDjvu.exe decryptor on your computer. Right-click on the file, and select “Run as Administrator” to launch the decryptor. Decrypting your data should start as soon as you’ve read the license agreement and completed the brief setup process. Keep in mind that if a file was encrypted using an unknown offline key or if it was encrypted online, this tool may not be able to decode it.

    However, before attempting any data recovery methods, you should check that the ransomware has been completely eradicated. It is recommended that you scan your computer with a specialized anti-virus software, such as the one we offer here on our site. You can also check individual files with the free online virus scanner.
