Mzop is a ransomware infection used by cybercriminals to extort money from unsuspecting web users through file encryption. Mzop typically scans the infected computer for a list of target files and renders them unreadable with the help of a secret encryption code.

Mzop is harmful software of the file-encrypting type that is actually a member of the most destructive malware family – the Ransomware family. This file-encrypting infection is especially harmful because it doesn’t really destroy the data on your computer, but simply locks it down and renders it inaccessible without the application of a decryption key. This is basically how traditional Ransomware software like Mzqw and Pouu works. Firstly, it encodes a list of common files and then, which is often a false promise, it requires you to pay ransom in order to decode your data to its normal state. On this page, however, we will do our best to help you remove Mzop and avoid the ransom payment by exploring some free file-recovery methods. Make sure you stay on this page and read the next lines in order to understand how to do that.

The Mzop virus

The Mzop virus is malicious software of the ransomware class that is programmed to blackmail web users to pay a ransom for restoring access to their digital information. The Mzop virus uses a ransom-demanding message to threaten its victims and to scare them into transferring money to a cryptocurrency wallet.

Mzop is a computer infection that can be caught in many ways. However, spam email messages, malicious attachments, and infected software bundles are the most likely sources of this Ransomware. Unfortunately, in many cases, the malware may sneak in the system with the help of a Trojan horse. The Trojan will basically find a weak spot in the system and exploit it, in this way allowing the ransomware to enter the computer without being detected.

Once Mzop gets inside the computer it immediately searches for files that are of great value to the victim and encrypts them all. Every file is consequently secured with a special encryption key. At the end of the attack, you suddenly find a ransom notification on the screen of your computer that typically contains a deadline and specific payment instructions. That is when you learn that your system has been attacked by the ransomware.

The .Mzop file encryption

The .Mzop file encryption is a malicious process aimed at restricting access to a list of user files. Typically the .Mzop file encryption is performed in the background of the system and cannot be detected by most security programs.

Mzop File

The criminals who have made Mzop will try to make you pay them as soon as possible and will not hesitate to threaten you as long as you agree to transfer the money they demand. Therefore, it is not a good idea to trust them. After all, they are the ones that compromised and attacked your computer with a ransomware variant and now extort money from you in exchange for recovering your personal files. That’s why, instead of hoping for their help, we suggest that you take the initiative in your own hands and remove Mzop rather than send money to anonymous crooks. Below you will find a free removal guide for that, as well as a professional removal tool and some free file-recovery suggestions.

As soon as a ransomware infection happens, a number of malicious processes begin operating in the system’s background. Therefore, the next step is to open the Task Manager, go to the Processes Tab and halt any processes you strongly believe are connected to Mzop.

You can start the Task Manager by pressing CTRL, SHIFT, and ESC simultaneously. If you find a process that you suspect is malicious and may be linked to the ransomware, simply right-click on it and choose Open file location.


Then scan the files in that location with the powerful free virus scanner below:

    You can End a process by right-clicking on it in the Processes tab and selecting the End Process option.



    If your computer has been infected by Mzop, you may not be aware of modifications to the Hosts file. In order to make sure that everything is correct, we suggest that you open your Hosts file and see what is added under Localhost

    To do that, press the Windows Key and R  and copy/paste the line below in the Run box that will open on the screen:

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

    Click the OK button in the Run window and as soon as you do that, you should see a file looking like this:

    hosts_opt (1)

    Please let us know if you find any virus-creator IPs in there, as indicated in the sample image above, so we can have a look at them and advise you on what to do.




    Many ransomware threats tend to alter your computer’s Registry by adding malicious files to it. Mzop is not an exception and if you are infected, you should scan the Registry for harmful entries and eliminate everything you feel is connected to the infection.

    To access the Registry Editor, just enter Regedit into the Windows search field and click Enter. Then, open a Find box in the Editor and use it to write the ransomware’s name inside. Next, start a search by clicking on the Find Next button to see if there are any entries with that name in it. There is a good chance that the ransomware is responsible for the items that show up in the search results.

    Be aware that making registry modifications might cause major system damage especially if you’re an inexperienced user and don’t know exactly which files are malicious and need to be deleted. Therefore, if this is your case, professional removal software should be used to eliminate any potential threats and dangerous files from the system and its registry.

    Once you are sure that the Registry is clean, you can close it.

    Next, we advise you to manually check the following locations by typing each of them (including the % symbol) in the Windows Search Field, opening them and looking for any newly added entries:

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

    Just check for anything new in the 4 locations above. In order to erase any temporary files that the ransomware may have created, you should select and delete anything that is stored in the Temp folder, which is No: 5.



    How to Decrypt Mzop files

    You may need various tools and techniques to decrypt encrypted data, depending on the ransomware variant that has attacked your machine. If you don’t know which is the variant that you are a victim of, this may be discovered by looking at the extensions that have been added to the encrypted files.

    New Djvu Ransomware

    Users are now being targeted by the latest Djvu ransomware strain, known as STOP Djvu. In order to assist victims identify their encrypted files, they should check for the suffix .Mzop at the end of them. STOP Djvu encoded files can only be decrypted if they were encrypted with an offline key. If you need assistance decrypting your data, we recommend you use the decyptor tool available on this link:

    To download the STOPDjvu.exe file from the URL, click the Download button in the upper right-hand corner of the window.

    You must run the decryptor file as an administrator and then hit the YES button in order to start the program. You can start the decryption process after you’ve gone through the license agreement and the brief instructions of use by clicking the Decrypt button. Please note that files that have been encoded using unknown offline keys or online encryption can’t be deciphered by this tool.
