Nuhb is a frightening ransom-demanding cryptovirus that can secretly encrypt your files. You will know that you have been infected with Nuhb when a notification suddenly pops up on your screen, and asks you to pay a ransom for the access to your files.

The Nuhb ransomware will leave a _readme.txt file with instructions

What you are experiencing is something typical for most Ransomware infections. If you have reached our page, you probably are wondering if there is any way around this danger. Luckily, our “How to Remove” team has prepared a detailed removal guide to help you deal with this highly dangerous Ransomware infection. If you read the next lines, you’ll discover some comprehensive directions that can assist you with the removal of Nuhb from your machine. You will also find suggestions for file recovery that do not involve paying ransom to the anonymous hackers behind this malware. ⠀

The Nuhb virus

The Nuhb virus is a very unpleasant money-extortion infection. As you become infected with the Nuhb virus, it immediately starts infiltrating your hard drive with the intention of encrypting a list of commonly used files.

The Nuhb virus will encrypt your files

Once they are located in the system, they are converted by the cryptovirus into a complex combination of symbols that cannot be opened with any program. Also, a new file extension may replace the default extensions of the affected files. This whole process can run silently in the background until all the data is encrypted, so it’s really hard to detect the threat before the ransom note appears on the screen, and tells the victims of the malicious results. Usually, the note involves a ransom-demanding message, and instructions on how to make the payment. The crooks promise to give you a unique decryption key in return for your money, which can decrypt your files, bringing them back to their former state. Bitcoins are usually asked by the fraudsters, as this is an untraceable online currency that helps them remain anonymous.

The .Nuhb file encryption

The .Nuhb file encryption can be reversed with the help of a special decryption key. Once you have been infected, the .Nuhb file encryption will be applied to all sorts of data that you keep on your system.

In this situation, you either have to meet the demands of the hackers, and pay the requested ransom, or you have to discover a way to remove the infection on your own, and attempt to restore your files without a decryption key. Both options cannot guarantee a 100% success, yet we believe the worse of the two is giving in to the demands of some unscrupulous cyber criminals, who only want to extort money from you by keeping your important files inaccessible. Moreover, there are many victims with bitter experiences from Ransomware attacks like Hajd, Ghas, who have duly paid the ransom only to eventually lose their money and never get a decryption key in return. This should make it evident just how unfair the “deal” with the hackers can be. That’s why our recommendation is that you should remove the infection, and explore some other file-recovery alternatives. Moreover, cleaning the computer is essential if after the attack you want to be able to use your system, and possibly recover some of your files. Once you do that, you can attempt to restore some of your data from system backups, external disk copies, or copies from a cloud storage. You can also check the entries in the list of free decryptors that we have on our site – the list is linked in the guide below.

Remove Nuhb Ransomware

Just as with most other ransomware variants, removing Nuhb requires complete focus and attention to detail. To avoid searching for this guide multiple times during the ransomware removal process, mark this page as a favorite in your browser and save the instructions for later use. Restarting in Safe Mode, which disables all but the most essential programs and services, makes it easier to identify and remove malware, thus we recommend you do that before you move to the instructions in the second step of this guide.

Open the Task Manager by pressing CTRL+SHIFT+ESC on your keyboard and look through the Processes tab for any suspicious processes. An emphasis should be placed on CPU and memory-intensive processes that look odd and cannot be linked to any of the programs that you normally run on the computer. If you detect a specific process that look suspicious, right-click on it and select Open File Location.

The powerful free online virus scanner below can be used to scan the files of the suspicious-looking process for malicious code. You can do that by dragging and dropping the files found in the File Location folder of a process that you suspect is harmful in the scanner and starting 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.

    If danger is found in the files, those files need to be deleted. First, however, you need to go back to the suspicious process and stop it by right-clicking on it and selecting End Process. After you do that, go back to the files and delete them from the system. If you do the other way round, some of the files may not want to be deleted while the process is still running.

    A ransomware may make some changes in the System Configuration settings, particularly the Startup tab, therefore, the next step is to go there and search for unwanted alternations and potentially unwanted startup items. You can easily  open System Configuration check what is listed in the Startup tab by typing msconfig in the Windows search bar, hitting Enter, and clicking on the result:

    You should uncheck any startup item that has an unfamiliar name or a manufacturer that you don’t trust. If you make any changes, save them and only leave the checkboxes next to legitimate startup items checked.

    Malware frequently targets the Hosts file on a computer. Therefore, the Hosts file should be opened in order to search for any malicious IP addresses listed under “Localhost“. To do that, press Windows and R at the same time and hit the Enter key to open a Run window. Next, in it, copy/paste the following line and press Enter:

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

    Once you see the Hosts file on the screen, go to Localhost in the text. Any IP addresses that look like the ones in the image below should be sent to us so that we can check them out. They will be examined by a member of our team to see if they pose a threat.

    In order to remain on the system longer and be more difficult to remove by inexperienced users, more advanced malware frequently adds harmful registry entries. Therefore, if you’ve had your computer infected by Nuhb, the ransomware may have added harmful files to your system registry that you don’t know about. In order to determine whether or not the infection is still present, you must run a Registry Editor check. This can be done in a variety of ways. One of the easiest ways is to type Regedit in the Windows search bar, and then press Enter. The CTRL and F keys can be used to open a Find window. In the Find box, type the name of the ransomware and the Find Next button.

    Delete any entries of the ransomware infection that are detected by the search. If needed, repeat the search again until no more entries are found. When deleting ransomware-related files, be aware that your operating system may be damaged if you happen to delete entries that are not related to the infection. On the other hand, Nuhb may reappear if you don’t remove all registry entries associated with the threat. For this reason, we recommend using an anti-malware software to scan your computer for hidden malware files and clean your registry thoroughly. 

    Ransomware-related entries can also be found in the following five places, which should be checked by hand. By typing their names into the Windows search bar and then pressing Enter, you can open them one by one. 

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

    Carefully search for recently added files in each of these locations and delete any potentially harmful files you find there. To complete this step, open the Temp folder, select all files, and then press the Del key on your keyboard to delete all the temporary files.

    How to Decrypt Nuhb files

    If ransomware is removed successfully, the next most pressing issue for those infected is how to decrypt their encrypted files. This procedure must be done with extreme caution because each ransomware variant has a different method of file-recovery that can be used. The encrypted file extensions are a good indicator of the variant of ransomware that you are faced with.

    Professional recommend that you use a trusted anti-virus program (like the one available on this page) to get rid of malicious software before trying to recover your files. Once you are sure that Nuhb has been completely removed from your system, you can safely experiment with various file-recovery methods and even connect backup sources to the ransomware-free computer.

    New Djvu Ransomware

    STOP Djvu, a new Djvu ransomware variant, has been discovered recently by professionals in the cyber security field. What distinguishes this infection from others is that, in most cases, the files encrypted with this threat end with the Nuhb suffix. The good news is that the decryptor in the following link may help you decrypt the data if an offline key was used to encrypt it.

    Once you click on the link above, click the blue Download button on the web page to start the STOPDjvu.exe download.

    To run the program, select “Run as Administrator” and then press the Yes button. Decryption can begin after you have read the license agreement and the brief instructions and have clicked the Decrypt button on the application’s toolbar. Unknown offline or online keys cannot be decrypted using this tool.

    Keep in mind that the anti-virus programs listed in this removal guide can help you quickly and easily remove the ransomware if you get into trouble. Alternatively, you can use a free online virus scanner to check suspicious files.
