Qqlo is a file-encrypting ransomware virus that can affect most all types of operating systems. Qqlo is highly dangerous and requires extreme care when dealing with its aftermath.

Ransomware has become the plague of the internet in recent years, generating millions of dollars in extorted money each year. Furthermore, every year experts record an exponential growth in numbers of these variants, which means that our cyber security is still a ways behind the criminals.

As far as Qqlo goes, you have probably found yourself among its latest victims and are now panicking about the data that it has essentially robbed you from. Ransomware like Ccza, Qqmt encrypts the files stored on your PC and then demands that you pay ransom in order to be able to access them again. Unfortunately, the future of your files is highly uncertain due to the complexity of the issue at hand.

Namely, even paying the ransom that the hackers require won’t guarantee that you will in fact be able to use your data again. You might not receive the necessary decryption key, or you might receive a corrupted or simply even just incorrect one. There are also alternatives that you can try, and we have listed some of them in the removal guide that you’ll find on this page. But before you attempt anything in regards to file-recovery, it is absolutely vital that you remove Qqlo first. And that we have also covered in the removal guide below.

The Qqlo virus

The Qqlo virus is a very harmful one due to the potentially devastating consequences it may have. Victims of the Qqlo virus may be permanently deprived of some of their most precious information.

And because ransomware has become such an undeniably massive presence on the internet, we think it’s paramount that more and more users take adequate measures to protect themselves from these attacks. For instance, regularly backing up your most valuable data and keeping copies on a separate drive that’s not connected to any network is a practically fool-proof ransomware prevention method. You can also store your backups on a cloud, if that’s what you prefer, although some experts would argue that that is a less secure alternative.

Also, we highly recommend having reliable antivirus software on your PC. It will keep it protected from potential backdoor viruses, such as Trojans, and sometimes perhaps even from ransomware itself. In addition, be sure to prevent vulnerabilities by constantly updating your system when updates become available.

The Qqlo file encryption

The Qqlo file encryption process itself is its main weapon not only because of its disastrous effects on people. The Qqlo file encryption is actually what also ensures that no antivirus program detects the ransomware.

Because encryption is in itself not a malicious process, but a very commonplace means of data protection. However, the sneaky criminal minds have found a way to use it for evil and have turned ransomware into one of the most profitable blackmail schemes on the internet.

Remove Qqlo Ransomware


If you want to get rid of Qqlo, one of the first things you should do is unplug your computer from the internet. This will prevent the ransomware from getting new instructions from its distant servers and will allow you to safely remove Qqlo. Next, you will need to disconnect any USB and external storage devices that have been attached to the system that has been infected to protect them.

After that, we recommend you to restart your computer in Safe mode before you move to the next steps. In the event that you need assistance with this particular task, please go to this page and simply follow the instructions given there to restart the system in Safe Mode. After the computer has completed the restart process, go back to this page (you may bookmark it now to keep it close at hand) and proceed to the instructions in step 2 from this guide.

Launching the Task Manager on the system that has been infected, is the next step. You can do that by simultaneously pressing the Ctrl, Shift, and ESC keys. Next, in the Task Manager window, select the Processes tab from the top tabs and search through the list for processes that have names that aren’t typical.

Search on the internet for further information on any process that seems to be questionable. You can scan the files of a process that look suspicious by right-clicking on it and choosing the Open File Location option.

    If you find any kind of danger in the files that have been scanned, you need to go to the Processes tab and end the process that is related to those files. To end the process, simply right-click on it, and then choose End Process from the option that appears. After that, any files that the scanner identifies as a threat should be removed from wherever they are stored.


    To verify that your Hosts file has not been altered without your knowledge, open a Run box by pressing the Windows key and the letter R simultaneously, then paste the following command and hit the Enter key.

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

    Check the Hosts file for any IP addresses listed under the Localhost entry that don’t seem to be trustworthy. If you come across IP addresses that seem suspicious, please let us know in the comments section below so that we may have a look at them and advise you on what to do if we discover anything strange about them.

    The next part of the system that has to be inspected by you is the System Configuration window. You may access it by entering msconfig in the Windows search field and then hitting the Enter key. After that, choose the “startup” tab to see the items that are loaded during startup. You should remove the checkmark from any startup item for which you have any reason to believe it is connected to the ransomware. To save your changes, click the “OK” button.


    It is necessary to do an exhaustive search of the Registry in order to remove any traces of Qqlo. That’s why, in this fourth step, we will explain to you how to search the Registry quickly and easily. In order to access the Registry Editor, type regedit in the search box on your Windows and then hit the Enter key.

    The next step is to open a Find box in the Registry by simultaneously pressing the Control key and the F key. This will allow you to look for files that are associated with the ransomware. After entering the name of the danger, proceed by clicking the Find Next button to start the search.

    Attention! Removing entries or making other modifications in the registry might cause significant issues across the system. For this reason, we strongly recommend that you make use of the professional malware removal application that is listed on our website to remove any Qqlo-related files are tucked away someplace on your system. If you use this program on your computer regularly, you may even be able to protect the system from being infected with new viruses and other forms of malware.

    Files related to ransomware might also be stored in the places listed below. So, after cleaning the Registry, use the Windows search field to paste each of the search phrases and open the locations one by one.

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

    You should look for potentially harmful files, but you shouldn’t delete anything until you are very certain that it poses a threat. The temporary files may be removed from the system without causing any damage by selecting everything in the Temp folder and then pressing the Delete key on the keyboard.


    How to Decrypt Qqlo files

    The process of decrypting data that has been encrypted by ransomware may be a challenging endeavor due to the fact that the decryption techniques that may be employed may vary based on the variant of ransomware that has infected your system. Checking the file extensions of your encrypted files is a good place to start if you want to determine what type of ransomware you are dealing with.

    Before beginning any data recovery process, it is necessary to perform a virus scan using an advanced anti-virus tool, such as the one on our website. Until the computer has been carefully scanned and reported to be virus-free, we do not recommend you to give a try to any methods of file recovery, as this may cause even more damage and loss of data.

    New Djvu Ransomware

    STOP Djvu is a new Djvu ransomware threat that encrypts data using a robust algorithm, and then asks victims for a ransom payment in order to decrypt their data. The .Qqlo suffix is often added to files that are encrypted by this threat. Before you think about paying ransom to the crooks, you should know that even if you have lost your data as a result of the Qqlo encryption, you can still make an attempt to recover it by using decryptors such as the one at the following website.


    You may get the executable file for STOPDjvu by clicking the link above, but, before you use the decryptor, you need to make sure that you have read the license agreement as well as the instructions that are associated with it. Bear in mind that this tool may be incapable of decrypting some types of encrypted data, particularly those that have been encrypted using unknown offline keys or online encryption. Nevertheless, we strongly recommend that you give it a go and abstain from paying the ransom under all circumstances.

    If the manual instructions in this article are unsuccessful in removing Qqlo, sophisticated anti-virus software may be used to remove the ransomware in a way that is both quick and effective. In addition to the professional software, you may do a manual check for malware on any file that you are concerned about by using our free online virus scanner.
