Qqri is a ransomware virus that belongs to the file-encrypting subtype. This makes Qqri among the most dangerous types of malicious code in existence.

Stop 2 1024x575

Every year ransomware variants cause businesses and even individuals millions of dollars in losses. And it’s all because of the mechanism by which this particular type of malware operates. Namely, it robs people of access to what can easily be considered one’s most valuable asset in today’s world: their information. By using complex encryption algorithms, variants such as Qqri, .Maas, .Zida ‘lock’ the files stored on the computers of their victims and make them inaccessible to anyone and anything. This means that no form of software will be able to open or read the files encrypted by Qqri. The only way you can decode those files and once again convert them into readable bits of data is by applying a special decryption key. And only the hackers behind this ransomware virus are in possession of that key, of which they have no doubt already informed you in the ransom note they left behind. This is the key that the criminals demand they be paid for. Well, luckily, that’s just what they would have you believe. In reality, there are also alternative solutions to this problem. And we strongly encourage victims of Qqri to try and use all those alternatives first, before agreeing to pay the criminals. On the one hand, this will save you a pretty decent amount of money. But on the other, this will also prevent the hackers from getting what they want, and it’s a small step forward in the overall fight against this threat.

The Qqri virus

The Qqri virus usually works in complete stealth and is able to avoid most antivirus tools. Thus, the Qqri virus could have easily been at work for hours on end without you even realizing it.

This is perhaps one of the main advantages of ransomware in general. And the trick is as simple as it is ingenious. Encryption in and of itself is not a harmful process. If anything, it was originally developed as a means to protect information from unwanted eyes, but as can be clearly seen in this example, it can also be used for bad. And that, in turn, is why most antivirus software won’t detect the ongoing encryption process as a malicious one.

The Qqri file decryption

The Qqri file decryption is made possible thanks to a decryption key that is unique to each and every instance of infection. The Qqri file decryption can occur after you’ve paid the ransom the hackers demand and receive the respective key. However, below we have listed a number of other possible options to recover your files. But before you attempt any of them, it is vital that you first remove Qqri from your system, and you can see how to do that in the first part of the removal guide that follows. Then you can proceed with the second part of the guide that focuses on file recovery.

Open the Task Manager by pressing Ctrl+Shift+ESC on your keyboard all at the same time. Then, in the Task Manager window, choose the Processes tab from the top tabs and go through the list of running processes for any oddly named ones. Keep an eye out for processes that are using a lot of resources for no obvious reason, and look online for some more information about them if you discover some.

Right-clicking on a suspicious process and selecting Open File Location from the context menu will allow you to quickly inspect its files for malware.


You may save time by dragging and dropping the files related to the problematic process in the scanner, which is available below.

    Go back to the Processes tab if you detect anything dangerous in the files that have been scanned. The process related to these files needs to be ended by right-clicking on it and selecting End Process from the context menu that opens. After you do that, it is important to delete any files that the scanner has flagged as potentially dangerous.


    The next step is to make sure your Hosts file hasn’t been modified without your approval. This may be done by opening a Run window by hitting the Windows key and R on the keyboard at the same time, then pasting and clicking Enter to run the following command.

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

    Pay attention to any IP addresses listed under Localhost that are not trustworthy. The IP addresses that seem suspicious should be reported to us in the comments section below so that we can investigate and come back to you with advice on what to do if we discover anything unusual.

    After you close the Hosts file, the next system location that you need to check is the System Configuration window. Typing “msconfig” into the Windows search box will save you time and open this window up. Click on the “startup” tab to see what startup items are loaded when the system first starts up. If you find a startup item that doesn’t look legitimate or is related to the ransomware, disable it by unchecking its checkmark.

    The Registry must be thoroughly scanned in order to remove any traces of Qqri from the system. For those who are unfamiliar with the Registry’s search options, launch the Registry Editor by entering regedit into the Windows search box and then clicking the Enter key and then hold down the Ctrl and F keys on your keyboard to open a Find box.

    The next step is to use this Find box to search for files associated with the malware. Type the name of the ransomware in the Find box and click on the Find Next button. If you detect files that are matching the name of the threat, pay extra attention.

    Attention! Making changes to the registry, such as deleting files, might result in major issues with the operating system. That’s why, in order to safely remove any Qqri-related registry entries, we strongly recommend using the professional malware removal application that we have provided a link to on our website. Unless you have extensive expertise and understanding, you should avoid deleting registry entries manually and choose a professional malware removal program instead. The Registry Editor may be closed once the search for ransomware-related files returned no results that need to be removed.

    For a more complete system inspection, we also recommend that you look for ransomware-related files in the following locations. Paste the search terms into the Windows search box, and then click Enter to open them one at a time.

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

    While it’s important to search for potentially harmful files, you shouldn’t delete anything until you are 100% certain that it is ransomware-related. The only files that it is safe to remove without causing a serious system harm are the temporary files in the Temp folder which you can select and delete with the Del keyboard key.


    How to Decrypt Qqri files

    Inexperienced users may have difficulty decrypting data that has been encrypted by ransomware. What is more, the decryption techniques used for specific ransomware versions may not have the same success with other versions. That’s why, the first thing that you should do before selecting a file-recovery solution is to look at the file extensions of the encrypted files on your computer to see which version of ransomware you’re dealing with.

    Also, don’t skip to run a full scan of the infected system with a powerful anti-virus program, such as the one available on our website to ensure that the computer has been completely cleaned from the malware and that there are no other security threats present on the system. Skipping this system scan may result in further damage and data loss, so don’t underestimate it.

    New Djvu Ransomware

    STOP Djvu is ransomware variant that can easily be recognized thanks to the .Qqri extension that it typically adds to the files it encrypts. If you’ve lost access to your data because of the Qqri encryption, don’t give up hope just yet. The following website has a decryptor that you may use to retrieve some of the encrypted data.


    Download the STOPDjvu executable file from the URL above and agree to the license to use the decryptor. Then, read the instructions of use and follow them to decrypt your files. Please note that even though this tool is a capable decryptor, it may not be able to decrypt data that has been encrypted online or with unknown offline keys.

    The professional malware removal program listed on this page may be used to do a comprehensive system scan to guarantee that Qqri has been completely removed. The free online virus scanner from the URL is another option for scanning suspicious files.
