However, since you are on this page reading an article about the Jjll cryptovirus, it is most likely that you are past that point and your computer has already been attacked by it. If so, then your files have likely been locked and you probably do not have a full data backup at your disposal. If that is the case, we strongly recommend you read the next lines and pay close attention to the instructions we have included in the removal guide for Jjll down below as doing this may help you save and clean your computer and maybe even recover some of your data from the ransomware’s grasp.

The Jjll virus

The newly released Jjll virus is a highly advanced threat and dealing with it could be a significant challenge even to experienced proficient IT specialists. The main purpose of the Jjll virus is to blackmail you by not allowing you to access, use or modify the personal files that you keep on your computer until you pay the ransom requested by the hackers.

According to a ransom note that is typically displayed on the user’s screen when their files get locked by this virus, the users are to receive a decryption key after they pay a certain sum of money following the instructions within the said note. Now, since you are reading this, we assume you would prefer to find a way around this payment request in which case we advise you to make use of the following Jjll removal instructions.

The Jjll file

The guide on this page and the removal tool we have posted in it should be enough to allow you to remove the Jjll file which will prevent the malware from locking any new files you may create on your computer. However, the ones that are already locked will likely remain that way in spite of you removing the Jjll file.

And in order to get them back you will need to take additional actions. Sadly, though we have included some data restoration suggestions and instructions in our guide, we can’t promise you anything. This particular threat uses a very advanced encryption algorithm and there are no surefire methods that can guarantee full data recovery. This, however, doesn’t mean that it’s a better idea to pay the demanded money. Remember that nothing can make the hackers keep their promises of restoring your data by sending you the decryption details. However, if you pay them the ransom they request, you will also be risking your money in the process which is why we believe it is better that you try all other alternatives first.

    A file titled Hosts should appear on the screen. Make a note of any IP addresses that seem to be suspicious under “Localhost” and drop them in the comments section after this article.

    You may also want to check the System Configuration pane for files relating to Jjll. To do so, type “msconfig” in the Windows Search bar and press Enter. Look at the “startup” tab to see what startup items have been checked on.

    You should remove the checkmarks from any startup items that you have strong evidence that are linked to the malware that you want to remove. If you’re uncertain about anything, research it online before making any changes.

    It is possible for malicious software such as Jjll to stay hidden in the registry for a lengthy period of time with the help of some secretly added malicious files. In order to prevent the threat from being reinstalled when a system is rebooted, you need to carefully search the registry for Jjll-related files that need to be deleted. The Registry Editor may be accessed by typing regedit in the Windows search bar and then pressing Enter from the keyboard.

    Find files connected with the infection in the Registry Editor by pressing the CTRL and F keys on your computer. Type the threat’s name into the Find box and choose Find Next to begin your search.

    Attention! Inexperienced users may have difficulties detecting and removing files associated with ransomware from the registry. On the other side, deleting registry items incorrectly might have a negative impact on the system’s overall performance and stability. Therefore, people who are not confident that they can handle Jjll should utilize a virus removal tool like the one available on this site.

    The following system locations should also be carefully checked for ransomware-related files as a precaution. To do that, simply go to the Windows search bar and type each of the search phrases listed above, then hit Enter to open them:

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

    If you see anything suspicious in any of the directories above, don’t remove it unless you’re confident it’s safe to do so. If you go inside your computer’s Temp folder, select everything, and then press the delete key on your keyboard and your computer will be clean of any temporary data.


    How to Decrypt Jjll files

    The decoding of ransomware-encrypted data may be a challenging task for even the most experienced professionals. Because of this, inexperienced users may have difficulty dealing with ransomware due to the fact that the different variants of ransomware may have different methods of file-decryption with different effectiveness. That’s why, if you want to deal with such a threat, it’s critical to identify which ransomware variant you’re confronted with. You may identify the ransomware by looking at the encrypted files’ file extensions.

    Bear in mind that, if the ransomware is still on your system, it will quickly encrypt whatever data you can recover. This is why it’s important to do a thorough scan of your PC before beginning any data recovery process. Anti-malware software is great for this purpose.

    New Djvu Ransomware

    STOP Djvu is a variant of the Djvu ransomware that is wreaking havoc on a number of computers and demanding a ransom from the victims. Files encrypted by this threat often finish with the .Jjll extension, which serves as an indication of the variant of ransomware that has infected you. For those who have confirmed that their PC is malware free, decryption may be possible with the help of a decryption tool like the one from the link below:


    A very important thing prior to decryption, is to make sure to read the license agreement and any accompanying instructions. This software’s ability to decrypt your data is not guaranteed, especially if the files were encrypted with an unknown offline key or an online encryption, so keep this in mind.

    If the manual methods discussed on this page are unable to remove Jjll entirely, antivirus software may be required. Our free online virus scanner may be used to manually scan any file you’re concerned about. Please feel free to leave a comment if you have any queries about anything covered in this removal guide.
