Hudf Virus


Hudf is a Ransomware virus that will blackmail you for access to your files by locking all your data and not letting you use it. The hackers controlling Hudf want you to send them money or they will never provide you with the access key for your data.

The Hudf virus ransom note

Hudf is a Ransomware cryptovirus that exists to make money for its criminal creators via online blackmailing. This computer threat uses the help of a very complex file encryption algorithm to secretly lock the personal files of the victims, which are stored on the infected machine. After the malware renders the files inaccessible, it typically generates a ransom-demanding message which demands that a ransom is paid in exchange for the locked data’s decryption.

According to security experts, Hudf infects its victims with the help of different malicious transmitters such as deceitful online messages, different attachments, spam emails, fake ads, misleading links, torrents and illegal webpages. That’s why, even if you are careful and try to avoid sketchy web locations and shady web content, there is absolutely no guarantee that you won’t bump into a Ransomware carrier when you least expect it. Just one click on one of the numerous transmitters may be enough to secretly activate the harmful payload of this malware and, unfortunately, you may not even have a clue about what has happened until all the files that you store on your PC get locked by its complex encryption. Normally, threats like Hudf and Shgv don’t show visible symptoms of their presence until they complete their criminal agenda and that’s why they are very difficult to detect and remove. The victims typically notice that they have been attacked by a Ransomware after it has completed the encryption process and has placed a ransom-demanding message on their screens.

The Hudf virus

The Hudf virus belongs to one of the most problematic malware families – the file-locking Ransomware cryptoviruses. A Ransomware cryptovirus like Hudf can render all important data on your machine unavailable with the help of a sophisticated process known as data-encryption.

The criminals behind Hudf normally require that a payment in BitCoins is made to a given cryptocurrency wallet. They insist that the ransom gets transferred as soon as possible and threaten that if they don’t receive the money within a given deadline, they will destroy the decryption key that can recover the encrypted files and this way make the latter inaccessible forever. If you agree to pay, however, they promise to send you that special decryption key and let you reverse the complex encryption that has been applied to your data.

The Hudf file

The Hudf file is a file that has the extension of this virus placed at the end of its name. Any Hudf file is actually a user file that has been encrypted by the Ransomware and cannot be accessed by any regular program.

In case you think that this is the best and the fastest way to deal with Hudf Ransomware and regain the access to your valuable information, however, you should better think again. Trusting the criminals with your money not only directly sponsors their blackmail scheme but also it can in no way guarantee the future of your computer and your files. The crooks may simply disappear once they get the money and you may never hear from them again, let alone receive the decryption key they promise. Or, they may decide to take their blackmailing game to the next level by asking you to pay more money after you’ve made the first transfer. There is also a high possibility that they may trick you by sending you another well-camouflaged malware that can further damage your computer instead of a decryption solution for your files. That’s’ why it is really not a good idea to trust anything they promise or give you. Instead, we suggest you focus on removing the existing cryptovirus infection and then explore some alternative methods of recovering your information. If you don’t know where to start, you can run a deep scan with the professional Hudf removal tool on this page and take a look at the removal guide below and the file-recovery suggestions that we have listed there.

Remove Hudf Ransomware


The removal of ransomware threats like Hudf may be a quite difficult task, especially if you are facing them for the first time. This being said, restarting the infected machine in Safe Mode may be more efficient in dealing with such an infection and for your convenience, we have included a link with instructions on how to reboot Windows in Safe Mode.

Before you restart the computer, however, make sure to bookmark this removal guide, so that you can simply reload the page and complete the rest of the steps when the system boots up.



After you enter in Safe Mode successfully, start the Task Manager, (press CTRL, SHIFT, and ESC), and then select Processes from the tabs at the top.

This will allow you to search for dangerous processes that are running without your knowledge. Pay attention to entries with strange names or processes that use a lot of CPU or Memory. In the event that a quick visual inspection does not reveal anything concerning about a specific process, the best course of action is to right-click on it, choose Open File Location from the pop-up menu, and scan the files of that process with a trusted scanner like the one that you can find below.


End the process if danger is found in its files and delete those files from the system.

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.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.


    Attention! There will be a lot of Registry files involved here! System corruption may occur if Registry changes and removals are performed incorrectly. To avoid involuntary corruption, please use the powerful removal program recommended on this page.

    Enter Regedit in the search field of Windows and open the Registry Editor.

    Once inside, press CTRL and F at the same time to open a Find window.

    Start a search by entering the ransomware’s name and clicking on the Find Next button on the right.

    If any entries with that name are found in your system’s registry, they must be deleted. However, you must proceed with great caution, since deleting entries that are unrelated to the danger may result in system harm. 

    If no more ransomware-related entries are found in the Registry, close the editor and manually search the following locations by typing them one by one in the Windows search bar:  

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

    To ensure that the ransomware hasn’t added any new files to these places, thoroughly inspect each of them. Select and remove everything in the Temp folder to get rid of all temporary files that Hudf might have created in the system.


    System files may be modified when the computer is compromised with malware. That’s why, in this step, we will show you how to check for unauthorized changes that may be a result of system hacking. To do that, press the WinKey and R together and open a Run dialog box on the screen. In the text field of the Run box, carefully copy and paste the following line, then click OK.

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

    In the Hosts file, scroll down and look for IP addresses like those seen in the following image:

    hosts_opt (1)


    Please, let us know if you see anything disturbing by leaving us a message with a copy of the questionable IPs in the comments section.

    Next, type msconfig in the Windows search field and open System Configuration. Next, go to the tab that says Startup and see whether Hudf has added any harmful Startup Items to the list. In case you’re unsure if a certain item is dangerous, do a fast web search to find out more about it. You should next uncheck the checkmarks of the items that you believe are linked to the ransomware, depending on your research.
