Qqjj

Qqjj is a very dangerous data-targeting piece of malware known as Ransomware. The mission of Qqjj is to lock up your files without harming them so that the people behind it can then demand a ransom payment from you for the release of the files.

According to a message that the Ransomware shows upon finishing the locking-up process of your files, there is only one way to recover your data and make it accessible again and that way is paying the blackmailers a set amount of money, after which you’d be sent a unique decryption key that only you can use to restore your data. Pretty much all modern Ransomware viruses like Qqmt, Qqlc, etc., work in this way and their purpose is always to harass their victims and force them to pay the demanded ransom sum. However, not everyone can afford to make the demanded payment, which is especially frustrating if the files locked by the malware are of high importance to the user.

Another thing we must say with regard to the ransom payment, however, is that, even if you have the needed money and can afford to give it to the cybercriminals who are blackmailing you, opting for that really shouldn’t be your go-to course of action. Instead, it’s much better to look at the payment option as a last resort variant one all other possible solutions have been tried and have yielded no results. The main problem with the payment is that the only thing it guarantees is you’d lose a significant amount of money in trying to restore your data. However, whether or not that data will be restored is uncertain and it is totally possible that you get nothing helpful in exchange for your money.

The Qqjj virus

The Qqjj virus is a malicious virus of the Ransomware variety programmed to use data encryption in order to prevent users from opening their files. The Qqjj virus creates a unique decryption key each time it encrypts the files on a given computer.

This key is stored on the hacker’s computer and remains there until the ransom gets paid. As we already mentioned, however, paying doesn’t really guarantee that this key would come to you.

This brings us to the main problem regarding Ransomware threats as a whole – there’s no universal way of handling these infections and getting the encrypted files released. There are alternatives that can be tried but their effectiveness varies. Nevertheless, we still highly recommend that you try those alternatives first, and only if none of them turn out to be helpful, give more thought to the payment variant.

The Qqjj file extension

The Qqjj file extension is a short sequence of characters added to the names of the encrypted files. Regular programs can’t recognize the Qqjj file extension and this is part of the reason you can’t open a file that has been encrypted.

It is futile to try to remove the Qqjj file extension manually because only decrypting the files with the correct key would make it go away. However, as we said, there might be other ways that can bypass the whole process of using the decryption key and we will tell you about them in our Qqjj removal guide.

Remove Qqjj Ransomware


Step1

Disconnecting your computer from the internet is one of the first steps you should take if you want to get rid of Qqjj successfully. You will then be able to prevent the ransomware from getting updated instructions from its remote servers. Next, it is also a good idea to unplug all USB and external storage devices from the computer to protect their data from potentially being encrypted.

After that, before moving on to the next steps in this guide, we strongly recommend that you restart your computer in Safe mode. If you find that you need help with this specific task, please go to this page and then just repeat the steps that are provided there in order to restart the system in Safe Mode. Once the process of restarting the computer has been done, you should go back to this page (you may bookmark it right now to access it later) and continue with the instructions that are provided in step 2.

WARNING! READ CAREFULLY BEFORE PROCEEDING!

The next step is to open the Task Manager on the computer that has been compromised. You can do this by hitting the Ctrl, Shift, and ESC keys all at the same time. Next, in the window for the Task Manager, click on the Processes tab from the top tabs, and then go through the list and look for any processes with names that seem unusual. Also, pay attention at the CPU and Memory usage of the listed processes, and if you notice that a particular process is using way too many resources without any good reason, do some research on it on the internet.

You may scan the files of a process that is questionable by right-clicking on it and selecting the Open File Location option from the context menu that appears on the screen.

To scan the files of a specific process, make use of the scanner that is located below and drag and drop the files from the file location folder in there.


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.

    If you discover any danger in the files that have been scanned, you need to go to the Processes tab and end the process that is associated to those files. If you did not find any kind of threat in the files that have been scanned, you may ignore this step. To end the process, just right-click on it, and when the context menu opens, choose End Process from the list of options. Following that, any files that the scanner deems as a danger should be deleted from their file location.

    Step3

    In the third step, you need to check that your Hosts file has not been changed without your knowledge. To do that, open a Run box by simultaneously pressing the Windows key and the letter R from the keyboard, then paste the following command in the Run box and hit the Enter key.

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

    In the Hosts file, search for IP addresses that are listed under Localhost but do not seem to be reliable. If you see IP addresses that appear fishy, please let us know about them in the comments below so that we can have a look at them and provide you with guidance on what to do if we find anything odd about them.

    hosts_opt (1)

    The System Configuration window is the next place of the system that requires your attention. You may open it by going to the Windows search bar, typing “msconfig“, and then pressing the Enter key on your keyboard. After that, choose the “startup” tab in order to examine the components that are loaded during system boot time. If you have any reason to assume that a startup item is related to the ransomware that you want to remove, then you should remove the checkmark from that item. Clicking the “OK” button will save your modifications in the end.

    msconfig_opt
    Step4

    In order to eliminate all traces of Qqjj from the system, it is required to do a thorough scan of the Registry. If you don’t know how to search in the Registry in a way that is both efficient and uncomplicated, then open the Registry Editor, by going to the Windows search box, typing regedit, and then pressing the Enter key on your keyboard.

    After the Registry Editor opens, press Control and the F key from the keyboard at the same time to open a Find box. The next step is to search for files that are related to the ransomware using this Find box. Once you’ve entered the name of the ransomware in it, you may click on the Find Next button.

    Attention! It’s possible that removing files from the registry or making other changes there may result in serious problems in the operating system. Because of this, we highly recommend that you use the professional malware removal tool that is linked on our website in order to delete any Qqjj-related files that are hidden in the registry. It is inadvisable to delete registry entries without having the necessary knowledge and experience.

    After the registry search shows no files linked to the ransomware, you may safely close the Registry Editor.

    For a more thorough check, we also recommend you search for ransomware-related files in the locations specified below. Use the search bar on Windows to paste each of the search words, and then open them one at a time by pressing Enter.

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

    You need to check for files that might be dangerous, but you shouldn’t remove anything unless you are very convinced that it represents a risk. You may delete the temporary files from the system without causing any harm to it by choosing everything in the Temp folder first, and then click the Delete key on your keyboard.

    Step5

    How to Decrypt Qqjj files

    The process of decrypting data that has been encrypted by ransomware may be a tough task for inexperienced users. This is owing to the fact that the decryption methods that may be applied may differ depending on the variant of ransomware that has infected your system. If you want to figure out what variant of ransomware you are dealing with, one smart place to start is by looking at the file extensions of the files that have been encrypted on your computer.

    It is essential to carry out a malware check on the infected machine with a sophisticated anti-virus application, such as the one that can be found on our website, before initiating any data recovery procedure. It is not recommended that you attempt any techniques of file recovery before the computer has been thoroughly scanned for malware and it has been shown that there are no threats present on the system. Skipping this system scan may cause even more harm and loss of data.

    New Djvu Ransomware

    STOP Djvu is a new Djvu ransomware threat that, after encrypting data with a powerful algorithm, would immediately demand a ransom payment from the victims in order to recover their data. The extension .Qqjj is often appended to the files that are encrypted by this new threat. Even if you have lost your data as a result of the Qqjj encryption, however, you can still make an attempt to recover it by using decryptors such as the one that can be found on the following website and this is something that you should definitely do before you consider paying the ransom to the criminals.

    You can get the executable file for STOPDjvu by clicking the link above; however, before you use the decryptor, you have to carefully read the license agreement, as well as the instructions of use that are associated with it. Keep in mind that this tool may not be able to decode all the encrypted data, and more precise data, that has been encrypted using unknown offline keys or online encryption. In spite of this, we recommend that you give it a go and under no circumstances pay the ransom that has been demanded.

    In the event that the manual removal guide provided on this page is unable to remove Qqjj successfully, you may get some help from more advanced anti-virus software to remove the ransomware in a manner that is both quick and effective. In addition to the professional program, you can use our free online virus scanner to do a manual check for malware on any file that you are worried about.
