Ransomware cryptoviruses such as Qqmt use encryption on the files of the targeted users and through that encryption make the data on the infected PC inaccessible. The purpose of this encryption is so Qqmt can later use the  locked files as blackmail leverage and force users to pay ransom to restore the access to any of the sealed files.

A simple, yet highly effective scheme that is currently one of the most widespread ways of extorting money from PC users through the use of malware.

If the personal data stored on your computer has recently become inaccessible and if each time you try to open a certain file a message comes up telling you the file has been encrypted by Qqmt, then you have most certainly had your machine infected with a ransomware cryptovirus. You might have already heard about this malicious category of computer threats and about their malicious capabilities but if you presently have such a piece of malware on your machine, then you need to be well aware of exactly how these malicious cyber threats operate and what your available options are at this point in time.

The Qqmt virus

In most cases, users learn about the encryption on their files and about the ransom through a message that the Qqmt virus puts on their screen after it has finished locking up the files. The message by the Qqmt virus is either generated on the computer’s desktop or within each folder that contains sealed files.

The said ransom notification also includes exact instructions that are supposed to guide the user through the process of paying the money so that it would be guaranteed that it is exactly the hackers who receive the sum. What’s not guaranteed however is that you’d actually restore the access to your files even if you issue the demanded payment. Remember, there’s always a chance that you might pay and yet receive nothing in return and be thus left with your files locked. This is the reason we have tried to offer you an alternative.

The Qqmt file encryption

The guide on this page is designed to provide solutions for the nasty Qqmt file encryption and make your PC safe for further use. However, one of the biggest problems with this type of ransomware is that the removal of the virus won’t do anything about the Qqmt file encryption. normally also result in the liberation of the files.

Qqmt File

Once the encryption is placed on the targeted data, there aren’t that many methods to have it removed. Of course, you can always go for the ransom and hope for the best. But as we already mentioned, even this won’t guarantee that your data will become accessible again and also, by paying the ransom, you’d be risking your money for a decryption key you might never actually receive.

That is why we’ve done our best to also include in our guide several possible methods that might help you recover some of the encrypted data without they need to pay anything to the cyber criminals who are trying to harass you. Sadly, even the suggested file recovery methods in our guide might not always yield the desired results which is why we can’t promise you that you’d get your files back even if you follow our instructions. It might seem like a lose-lose situation and sometimes it might indeed be like that which is why those viruses are really some of the worst.

Still, you shouldn’t lose hope – security experts are working day and night to come up with better and more effective solutions and as soon as something new comes up that can help users deal with threats like Qqmt, we will make sure to inform our readers about it.

It’s really important to stay safe on the Internet and to avoid anything that might compromise your PC’s defenses such as spam messages, shady ads, obscure offers, fishy sites and pirated or low-quality downloads. One great tip against ransomware is to get a backup for any files on your PC that you value since placing copies of them on a backup location or device is sure to keep them safe even in the event of a ransomware cryptovirus attack on your PC.

Remove Qqmt Ransomware


The first step after you realize that your computer has been infected with Qqmt that we recommend you to do is to disconnect it from the Internet. Also, it is a good idea to unplug any USB drives or external disc devices that are connected to the infected machine.

Once you do that, we recommend you to restart the system in Safe Mode. You can use these detailed instructions if you need help with the Safe Mode restart.

For your convenience, you can bookmark this page so that when the computer restarts, you can easily return to it.

In the second step, you need to check for malicious processes in the Task Manager. To open it, press and hold Ctrl, Shift, and ESC on your keyboard simultaneously. After that, go through the list of processes that are currently running on the computer and look for anything with an unusual name. You may save time by sorting the processes based on how much CPU and memory they are using. Search for processes that seem to be using a significant amount of resources for no apparent reason, and if you find any of them, research about them on the internet to find out more information that can show you if they are dangerous.


You can do a fast scan for malicious files by right-clicking on a process that seems fishy and selecting Open File Location from the context menu. Then, drag and drop the files from the file location folder into the powerful scanner below.

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.

    Return to the Processes tab if you discover anything potentially dangerous in the files that have been scanned. Right-click on the process that is associated with the malicious files, and choose End Process from the options. After that, delete any files that the scanner has identified as potentially harmful from the folder in which they were stored.


    After that, you will need to check whether the Hosts file on your computer has been modified in any way without your permission. You can do that that by using the Winkey + R keys shortcut. Then, paste the command below inside the Run box on your screen and press the Enter key on your keyboard.

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

    If you come across any IP addresses under Localhost that appear fishy, please let us know in the comments section below so that can investigate them and get back to you with some recommendations on what to do if we discover anything troubling.

    Next, go to the Windows search field and type “msconfig” in the search box. Open System Configuration and go to the “startup” tab to take a look at what startup items are set to load when the system is first powered up. Unchecking the checkbox associated with a startup item allows you to disable that item if it does not seem to be legitimate or is linked to malware.

    The next very important step in removing Qqmt is related to the Registry Editor. In it, you will need to search the Registry for files that are associated with Qqmt. To do this, open the Registry Editor by entering regedit in the Windows search bar and then clicking the Enter key on your keyboard. Then, simultaneously press the Control key and the F key on your keyboard to open the Find box.

    Use this Find box to search for files related to the threat by simply typing the name of the ransomware in the Find field, and then clicking the Find Next button. If you find files with the same name as the threat, pay close attention to them, but do not delete anything until you are one hundred percent certain that it is safe to do so.

    Attention! When done improperly, removing files from the registry might result in unpredictable issues with the operating system. Because of this, we strongly recommend you to use the professional malware removal program that is linked on our website to prevent any unintended harm to your computer. This program will help you to remove any Qqmt registry entries and will minimize the risk of deleting something else by mistake.

    After you have cleaned the registry, and if there are no more ransomware-related files found in the search results, you can safely exit the Registry Editor.

    An extra step that we suggest is to search for ransomware-related files in the locations listed below. To open each of them, you need to type it in the Windows search box and then click the Enter key.

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

    You should check for files that have strange names, such as a name that contains random symbols or letters. It goes without saying that you should not delete anything until you are one hundred percent certain that it is associated with ransomware. It is safe to delete just the temporary files that are located in the Temp folder on your computer; these files may be selected and deleted by using the Delete (Del) key.


    How to Decrypt Qqmt files

    When it comes to the decryption of ransomware files, the decryption techniques that have been created for some ransomware variants may not perform as well on others. That’s why, checking the file extensions of the encrypted files in order to identify the variant of ransomware that was used to encrypt them should be the first step in the process of selecting a method for data recovery.

    Before moving forward with any other action, you should first do a comprehensive scan of the infected machine using a powerful anti-virus application, such as the one that is available on our website. This is a very crucial step to do in order to check that the computer has been cleaned of any malicious software. It is important not to minimize the risks associated with missing this system check, since doing so might lead to significant damage as well as the loss of even more data.

    New Djvu Ransomware

    STOP Djvu is a ransomware variant that typically adds the .Qqmt extension to the files it encrypts. Do not give up hope just yet if the Qqmt encryption has restricted access to your data. There is still a chance that it can be saved, and you should be able to decode some of the encrypted data by using the decryptor that is located on the following website.


    Use the link above to download the STOPDjvu executable file. Reading and carrying out the steps outlined in the software’s instructions is all that is required to successfully decrypt your data. Please note that, despite its promising capacity to decrypt data, it is possible that this program may not be able to decode files that have been encrypted online or using offline keys that have not been identified.

    If you want to be sure that Qqmt has been completely removed from your system, you should run a complete scan of your computer using the professional malware removal program that is linked on this page. The online virus scanner that may be accessed through the URL is one more option for identifying potentially malicious files.
