What Is Wsuu Virus
The Wsuu virus is a harmful piece of software that is part of the well-known STOP/DJVU ransomware family. This virus operates by encrypting files and tagging them with the .wsuu extension, after which a ransom demand note is released. This note orders victims to pay a specified sum in exchange for a decryption key that will enable them to regain access to their files. The catch, however, is that failure to meet the payment deadline could lead to permanent data loss.
Quick Step-by-Step: Removing WSUU Virus
1. Keep Your Data Safe: Before diving in, always make a copy of files that the virus might have reached. It’s like having a safety net for your data.
2. Switch to Safe Mode: Power up your computer in Safe Mode. This mode only lets the most basic parts of your computer work, so it’s easier to clean up the virus.
3. Choose a Solid Cleanup Tool: Find a well-reviewed anti-malware tool to search for and remove the harmful software.
4. Use a Previous Save Point: If you’ve ever saved backup points for your computer, consider using one from before the virus showed up.
5. Say No to Paying: Remember, giving in to the ransom demand doesn’t promise your files will come back. Plus, it supports their bad behavior.
To protect yourself later, make regular copies of important files, install a top-notch antivirus program, and always think twice about clicking on unfamiliar emails or links. If you ever feel stuck, it’s a good idea to reach out to a computer security pro.

What Is Ransomware?
Ransomware is a malicious software type that takes a user’s data hostage once it infiltrates their system. The user’s files get encrypted, and they are prevented from accessing them until a ransom has been paid. The spreading agents of this malware include masked files, misleading emails or links, or through software vulnerabilities.
Wsuu Virus – How Did I Get Infected?
The Wsuu virus makes use of security vulnerabilities in your OS or software to gain entry into your system. This can happen through misleading emails, harmful web content, and concealed files.
- It might be through an email attachment or a link.
- It could be from downloading from an untrusted website.
Wsuu Virus – What Does It Do?
After gaining access, the ransomware implants malicious payload files into specific system directories such as:
- %Local%
- %Temp%
- %Windows%
- %SystemDrive%
- %LocalLow%
- %AppData%
- %System%
- %system32%
The Wsuu virus then distributes a ransom note in the form of a file named _readme.txt containing the following text:
Windows Run and RunOnce Registries may be populated with Registry values generated by the Wsuu virus.
What Are .wsuu Files
The .wsuu files are those that the ransomware has encrypted using the AES encryption algorithm. To decrypt these files, one must either pay the ransom or utilize a trusted data recovery tool. The virus mainly targets specific types of files:
- Video files (.mp4, .avi, etc.)
- Audio files (.mp3, .wav, etc.)
- Image files (.jpg, .png, etc.)
- Archive files (.zip, .rar, etc.)
- Document files (.docx, .pptx, etc.)
- Other file types
Example: Picture.jpg.wsuu
How to Open .wsuu Files
If your system is compromised by the Wsuu ransomware virus, the first action is to remove the harmful software and attempt to recover the files from a backup. It is generally impossible to regain access to the encrypted files without satisfying the ransom demand of the cybercriminals. The same approach applies to a system infected with DJVU ransomware.
What To Do If My Files Are .wsuu?
The only reliable way to regain access to your .wsuu files infected by the Wsuu ransomware virus is by restoring them from a backup or trying to reverse the encryption with a cipher. If there are no backups available, data recovery using specialized software may be attempted, but there is no guarantee of success.
How To Safeguard Windows from Wsuu In The Future?
To prevent future infections from the Wsuu ransomware virus, it is crucial to regularly update your system with the latest security patches, backup your data frequently, practice safe web browsing habits, and be careful with the files you download.
How to Eradicate Wsuu from Windows?
The Wsuu ransomware virus is challenging to remove due to its complex nature. You should seek professional assistance or employ a trusted anti-virus software program. Be wary that even after removal, the encrypted files may still remain inaccessible.

- Step 2
- Step 3
- Step 4
- Step 5
Step 1: Scan for Wsuu with SpyHunter Anti-Malware Tool

Step 2: Uninstall Wsuu and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Step 3: Clean any registries, created by Wsuu on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Wsuu there. This can happen by following the steps underneath:
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Wsuu
Step 5: Try to Restore Files Encrypted by Wsuu.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:

4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Wsuu aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
