Ufwj Virus


Ufwj is a Ransomware-based piece of malware that is used for blackmailing web users by keeping their files hostage through encryption. What Ufwj does is, it secretly encodes a list of user files and demands a ransom payment to decrypt them.

Recently, we have received numerous requests from users to help them tackle this threat and recover some of their valuable information. So, here is a comprehensive guide on how to remove the Ufwj Ransomware from any computer that might have been infected. You can read more about the specifics of the infection in the next lines. We will cover its distribution methods and the measures you can take to prevent a future encounter. Hopefully, the details you will find below will be helpful and allow you to reduce the negative effects of the Ufwj or Gujd attack.

The Ufwj virus

The Ufwj virus is a money-extortion tool that falls into the category of Ransomware. The Ufwj virus can scan a computer for specific file types and encode the present data with a strong encryption algorithm.

Once the targeted files have been encrypted, they cannot be opened again unless a special decryption key is applied to them. In this way, the crooks behind the malware keep various types of digital data hostage until an amount is paid as a ransom for its release. This is a method for money-extortion that is a favorite “business model” for many cyber criminals. The reason for this is simple – people are often pay the ransom for their information’s release and that turns out to be extremely profitable for the hackers behind Ransomware infections like Ufwj.

The Ufwj file encryption

The Ufwj file encryption is a complex code that is designed to keep user data inaccessible for an indefinite period of time. Users can remove the Ufwj file encryption from their files only after they apply a matching decryption key.

Our “How to Remove” team would advise you to not panic if your files have been encrypted by Ufwj because this will only limit your ability to make a rational and logical decision about what to do next. Fortunately, there are some options that may be worth your attention since they don’t involve paying a ransom to some anonymous hackers.

The most important thing now is to remove the Ransomware and you should ideally start from there. This is crucial if you intend to give a try to some file-recovery methods, such as the ones mentioned in the removal guide below. After all, you don’t want your recovered files to become encrypted again, right? So, our suggestion is to start with the removal guide below and follow its instructions. If you have personal file backups – that’s perfect! Once you remove the infection, you can simply copy your files to the clean computer. Extracting file copies from system backups may also be a solution that is worth the try. Alternatively, you may want to contact a security professional of your choice which is still a better option than sending money to anonymous cyber crooks. After all, there is absolutely no reason to trust online criminals, let alone hope that they will send you a decryption key for the files their malware has encrypted.

Remove Ufwj Ransomware

Ransomware infections like Ufwj may require your full attention in order to be removed successfully. In addition to that, the removal process of the malware may require several system reboots. Therefore, if you want to follow the instructions from this guide, it is best to first bookmark this page in your browser, so you can reload it quickly and continue from where you left.

Also, we recommend that, during the removal process, you reboot the compromised computer in Safe Mode in order to run only the most essential processes and programs and limit the activity of the infection as much as possible.


After you enter in Safe Mode, open the Task Manager (CTRL + SHIFT + ESC key combination) and head to the Processes Tab. In it, search for processes that look suspicious, have an unusual name, or use a lot of CPU and Memory without any particular reason. If you detect a process that you think could be dangerous, select it and then right-click on it. Then, from the pop-up list of options, select Open File Location.

As soon as the File Location folder of the selected process opens, drag and drop the files stored there in the powerful free online virus scanner below to check them for malicious code:

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.

    If malware is detected in any of the scanned files, this is a sure sign that you must end the processes by right-clicking on it. It is also very important that you delete the dangerous files and their folders from the computer. 

    Don’t hesitate to check the files of every process that you find suspicious and act accordingly in case danger is detected. You can also research every questionable process online in order to get more information about its origin and legitimacy before you decide to stop it.

    In case of a ransomware infection, there might be changes in some key system files. One of the system files that often becomes target for malicious changes is the Hosts file of the computer. That’s why in this step you need to open the Hosts file (simply copy this line notepad %windir%/system32/Drivers/etc/hosts in the Start menu search bar and open the result) and check for any malicious IP addresses under Localhost in the text.

    If you detect a virus creator IP in your Hosts file, just like in the example image, please paste it in a comment below this post, and we will check it out.

    A ransomware infection such as Ufwj may also make some changes in the System Configuration settings, and more precisely in the Startup tab. For instance, the threat may add malicious Startup items that start running as soon as the computer starts. That’s why the next thing that you need to do is to open System Configuration (Type msconfig in the search field and open the result) and click on Startup: 

    Then carefully take a look at the startup items listed there and if you detect something suspicious, (it could be an entry with an odd name or an unknown manufacturer), uncheck its checkmark to disable it.  When you are sure that only legitimate entries are enabled in the list, click OK to save your changes.

    Many sophisticated malware infections tend to add malicious entries in the registry in order to gain persistence and to make it more difficult to get removed by inexperienced users. Ufwj is not an exception and might have added some malicious files in the registry of your system without your knowledge. That’s why, in this step, you need to open the Registry Editor (Type Regedit in the windows search field and press Enter) and carefully search for entries related to the infection. A quick way to do that if you are not a professional is to use the CTRL and F key combination to open a Find window and write the name of the ransomware in it. Then simply click on the Find Next button to start a search.  

    If anything is found, it needs to be deleted from the registry. However, you must be extremely careful. If you delete other entries, unrelated to the ransomware as this may corrupt your OS. If you leave Ufwj-related entries in the registry, however, the malware may not be fully removed. Therefore, if you are not sure, we recommend that you use a professional removal tool that can scan your computer and clean any dangerous files that might be hidden or left behind.

    Next, when you are sure your job in the Registry Editor is done, close it and type each of the lines below in the Start Menu search bar:

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

    Check each of the locations for recently added malicious entries.

    When you open Temp, select everything there and delete it to remove any temporary files that Ufwj might have created. 

    How to Decrypt Ufwj files

    Something that is specific for most ransomware infections is that after you remove the malware, the files that have been encrypted may not get back to normal.

Unfortunately, no one can guarantee how many files can be saved after such an infection, but we have a comprehensive guide that contains some of the best alternatives on how to decrypt your files if they have been encrypted.
