Adlg

Adlg is a stealthy computer infection that belongs to the Ransomware family of viruses. Threats of Adlg make their victim’s files inaccessible via encryption and demand payment for the release of the affected data.

If you are among the numerous Adlg, Ofoq, Oflg victims, you are probably aggravated and frustrated by the fact that you are no longer able to open any of your personal data present on the infected machine. We understand your frustration – it can be very unpleasant to get your data locked by a Ransomware, especially if the files that it has targeted are important to your work or education, or if they hold high sentimental value for you. However, acting out of desperation is never the answer – in most cases, all this would do is make things even worse for you. Therefore, it is essential that you stay collected and read the information from this post in order to learn what you options are, what pros and cons they have, and how you could make the optimal decision with regard to what to do in your particular case.

The Adlg virus

Adlg is a virus program intended to keep your files inaccessible unless you pay to get them released. Infections like the Adlg virus are known as Ransomware, and they employ file-encryption to keep your data sealed.

The Adlg virus will encrypt your files

After a Ransomware attacks the computer, it initially stays hidden in the system and it takes its time to locate and lock all files in the computer that belong to certain predefined formats. Usually, most Ransomware threats targeted data formats that are commonly used, and oftentimes hold sensitive and important info. Those could be different text document formats, image files, audio and video files, spreadsheets, presentations, schematics, 3d models, and so on. 

Once the virus locates those files, it starts an encryption process that quickly converts the files into unreadable pieces of data. The only way to make the files accessible again is by applying a special key that is unique for each encryption instance. What this means is that you cannot use another victim’s key – only the key generated for your computer specifically will allow you to open your files. Of course, this key is in possession of the hackers, and they want you to pay money to get it.

The Adlg file extension

The Adlg file extension is a suffix that renames your files during the encryption process. Regular programs don’t recognize the Adlg file extension, which is what renders all affected data inaccessible.

We, as well as most other security researchers, would advise Ransomware victims like you to hold off the payment. Sending the requested money might indeed get you the key for your files, but it may also turn out to be an utter and pointless waste of resources. You got to keep in mind that there is nothing you could do if the hackers decide not to send you the key after you pay them. Indeed, there are quite a few instances of this happening to Ransomware victims, so we advise you to at least try some of the other options that might be available to you. 

Of course, if nothing else works, you can still pay the ransom if you are willing to risk your money in this way. However, you must remember to still remove the virus from your computer, and the instructions below will show you how. Keep in mind that if you don’t get rid of Adlg, it might encrypt new files you download or create in your computer. Furthermore, it might also infect external devices you connect to the PC. If you have external backups, make sure to only connect them to the machine after you are hundred percent certain the malware is gone. In case you cannot find any backed up data, you should try the suggestions from the recovery section of the guide – we cannot guarantee they will be effective, but you should still try them before you think about paying the ransom.

Ransomware threats like Adlg tend to run dangerous processes on the computer. In order to remove the virus, you have to detect these processes, stop them, and delete their related files from their file locaiton. This can be done by going to the Windows Task Manager (press CTRL + SHIFT + ESC keys simultaneously to open the Manager) and opening the Processes Tab.

Once you get there, carefully look at the listed processes and detect those that operate oddly, use too many system resources or look dangerous and unrelated to anything that you are normally running on your computer.

Right-click on every questionable process and from the menu that pops up click on Open File Location. Drag the files from that location in the free online virus scanner that is available here and run a file check:

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.

    When the check completes, end the processes whose files get flagged are infected and delete their folders from the file location. 

    Step3

     

    Many ransomware infections don’t come alone. They typically sneak into the computer with the help of other malware. That’s why it is a good idea to check if your computer is hacked. To do that, you need to open the Hosts file by pressing the Start Key and R and pasting the following line in the Run window that appears:

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

    Don’t forget to click the OK button to run the command that you have pasted. If your computer is hacked, when you reach Localhost, you will see a lot of questionable IPs below just as it is explained on the image here:

    hosts_opt (1)

     

    Important! Please leave us a comment below this post if you see suspicious IPs below “Localhost” in your Hosts file.

    Next, go to the windows search field and type msconfig. Hit the Enter key and the System Configuration app will open immediately. 

    msconfig_opt

     

    Select the Startup tab and look for entries that seem to be related to Adlg or look suspicious and have “Unknown” as Manufacturer. Remove the checkmark before these entries and leave checked only the entries that are legitimate. If you are not sure about a given process, research it before you do anything.

    Step4

     

    Threats like Adlg may make changes in the Registry of the infected computer and may add some malicious directories that need to be detected and deleted if you want to successfully remove the virus. That’s why, after you complete the steps above, open the Registry Editor by typing Regedit in the windows search field and pressing the Enter key. After that, use the Find function (press CTRL and F keys together to open it) and type the exact Name of the ransomware threat in the empty text field. Click on the Find Next button to search the registry for malicious entries. When the search completes, delete the malicious entries that are found. When no more results are found with the Find function, it is time to manually type each of the following in the Windows Search Field:

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

    In each of the listed folders, look for recently added files. Delete the content of the Temp folder. 

    Attention! Be very careful with the deletions in the Registry Editor! Deletion of the wrong entry may lead to serious system corruption.

    If you have questions or concerns, please leave us a comment in order to avoid involuntary system damage.

    How to Decrypt Adlg files

    In order to restore access to files locked by Ransomware, victims may need to try several different methods until they find the one that works for them. Unfortunately, there is no guarantee for anything, but before attempting to decrypt your files using the method outlined below, you must first figure out which strain of ransomware is responsible for the encryption. You can find this information if you check the encrypted files’ newly-added file extensions.

    New Djvu Ransomware

    At the time of writing, STOP Djvu ransomware is the most recent variant of the Djvu ransomware that is aggressively spreading to infect computers around the world. Files encrypted by this ransomware will typically have the .Adlg extension added to them after the attack. Even tough this is a new threat and the decryption solutions for it are very limited, below, you’ll find a link to a decryptor tool that may be helpful in decoding your data:

    https://www.emsisoft.com/ransomware-decryption-tools/stop-djvu

    To start the decryption, you first need to save the STOPDjvu.exe file to your computer from the URL above and then click the Download button in the upper right corner of the window.

    Next, click on the saved file and select Run as administrator, then confirm with “Yes” to open the file. After reading the license agreement and the quick setup instructions, press the Decrypt button to begin the decrypting process. Please keep in mind that this decryptor cannot decrypt files encrypted with unknown offline keys or online encryption.

    To improve your chances of getting your files back, you should first carefully remove the ransomware from the system that was infected. Removal of Adlg and other malware is possible with the help of a professional anti-virus tool (like the one on this page) or a robust online virus scanner. If you have any questions or concerns about this guide, please don’t hesitate to leave a comment below, and we will do our best to get back to you as soon as possible.
