How to remove Wnlu ransomware

Wnlu ransomware is a type of malware that encrypts personal files using an army-grade algorithm

Wnlu ransomware is a cryptovirus that belongs to a malware family known for years. Due to this relation, the threat is considered one of the most dangerous and damaging pieces of malware active these days. This malware encrypts all the important files on a Windows computer (appends them with .wnlu extension) and restricts access to them. Then the version of Djvu ransomware delivers a traditional piece of file – the ransom note.

This piece is created a long time ago and is not changed at all. The file name, contents, and the ransom amount are all determined back in 2019 and never altered. In the ransom note _readme.txt, cybercriminals behind the attack explain that the only way to recover data is by paying ransom in Bitcoin – the sum can vary, depending on how soon the victim contacts criminals. The first 72 hours offer a 50% discount from $980 to $490.

While it is true that Wnlu virus file decryption requires a unique key to unlock them, experts^[1] recommend not paying the ransom, as cybercriminals might not keep their promises, resulting in financial losses. In this article, we will explain how to get rid of malware and use alternative methods for data recovery.

The ransomware is a virus that attacks Windows computers by using various infiltration methods. Once inside, it uses an encryption algorithm to lock up all documents, archives, videos, music, and other files, adding its unique extension to them.  According to the virus authors, victims need to contact them via manager@mailtemp.ch and helprestoremanager@airmail.cc emails and provide their personal ID for identification and further help.

Once that is done, users should receive further instructions to proceed with the payment, provided in Bitcoin cryptocurrency. However, we do not recommend contacting the attackers because they might not deliver the required decryption tool. Check out the alternative methods we provide below instead. Paying is never a good idea, especially when it comes to these advanced threats in the particular family. Wnlu file virus is from the Djvu ransomware family that is not stopping. New versions come every week, and the latest ones are Moia virus, Cool virus, Palq.

Offline and Online IDs and decryption

Your success in decrypting the .wnlu files depend on which ID was given to you. IDs can be offline and online, but they are not always used interchangeably. Offline keys are explicitly created for situations when a virus cannot access its servers or get online. Instead, it uses this unique built-in code with a specific kind of encrypted data that only can be unique for the version, not the targeted machine.

The Wnlu virus is more dangerous than ever. It was previously possible to get your files back when the threat managed to infect a machine, but these newest versions have software improvements now. These newer versions use specifically online ID forming methods, making it impossible for victims to restore their data without assistance from technical experts.

This ransomware is clever, and it gets various improvements over time. Wnlu ransomware generates a new key for each computer it infects and holds encoded data hostage. Sometimes when offline IDs are used in creating encryption schemes there is just one master decryption key available to unlock all of their victims' encrypted files- no matter how many people get victimized by such malware infection!

If your computer got infected with one of the Djvu variants, you should try using Emsisoft decryptor for Djvu/STOP. It is important to mention that this tool will not work for everyone – it only works if data was locked with an offline ID due to malware failing to communicate with its remote servers.

Even if your case meets this condition, somebody from the victims has to pay criminals, retrieve an offline key, and then share it with security researchers at Emsisoft. As a result, you might not be able to restore the encrypted files immediately. Thus, if the decryptor says your data was locked with an offline ID but cannot be recovered currently, you should try later. You also need to upload a set of files – one encrypted and a healthy one to the company's servers before you proceed.

• Download the app from the official Emsisoft website.
• After pressing Download button, a small pop-up at the bottom, titled decrypt_STOPDjvu.exe should show up – click it.
  
• If User Account Control (UAC) message shows up, press Yes.
• Agree to License Terms by pressing Yes.
  
  
• After Disclaimer shows up, press OK.
• The tool should automatically populate the affected folders, although you can also do it by pressing Add folder at the bottom.
  
• Press Decrypt.
  
  

From here, there are three available outcomes:

1. “Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
2. “Error: Unable to decrypt file with ID:” means that the keys for this version of the virus have not yet been retrieved, so you should try later.
3. “This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.

Removing the threat and repairing the system

If you are the victim of Wnlu ransomware, we recommend that users employ anti-malware software to remove it. Some types are capable of self-destructing after the file encryption process has finished, and even in such cases, there may be various data-stealing modules left behind on your device. Threat pieces like this can ensure persistence or operate together with other malicious programs already installed on the machine. Run the app like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes to find and terminate the infection.

Manual removal is not recommended unless you have advanced skills in IT. Wnlu crypto-malware can scatter its malicious files across the system and hide them inside different folders, making them difficult to locate for average users. Without proper guidance from an expert on how best to remove these infections manually, you may trigger issues with the machine. However, it is possible to remove the virus with minimal risks involved.

Security tools or AV detection^[3] applications are two programs that will efficiently detect all ransomware-related applications as well any other viruses hiding within your machine's operating system. Having simple solutions can help quickly terminate the virus, so you can move on with system repair and .wnlu data recovery.

Once a computer is infected with malware, its system is changed to operate differently. For example, an infection can alter the Windows registry database, damage vital bootup, and other sections, delete or corrupt DLL files, etc. Once a system file is damaged by malware, antivirus software is not capable of doing anything about it, leaving it just the way it is. Consequently, users might experience performance, stability, and usability issues, to the point where a full Windows reinstallation is required.

Therefore, we highly recommend using a one-of-a-kind, patented technology of FortectIntego repair. Not only can it fix virus damage after the infection, but it is also capable of removing malware that has already broken into the system thanks to several engines used by the program. Besides, the application is also capable of fixing various Windows-related issues that are not caused by malware infections, for example, Blue Screen errors, freezes, registry errors, damaged DLLs, etc.

• Download the application by clicking on the link above
• Click on the ReimageRepair.exe
  
  
• If User Account Control (UAC) shows up, select Yes
• Press Install and wait till the program finishes the installation process
• The analysis of your machine will begin immediately
• Once complete, check the results – they will be listed in the Summary
• You can now click on each of the issues and fix them manually
• If you see many problems that you find difficult to fix, we recommend you purchase the license and fix them automatically.

By employing such a tool, you would not have to worry about future computer issues, as most of them could be fixed quickly by performing a full system scan at any time. Most importantly, you could avoid the tedious process of Windows reinstallation in case things go very wrong due to one reason or another.

Restoring Wnlu virus files

Since many users do not prepare proper data backups prior to being attacked by ransomware, they might often lose access to their files permanently. Paying criminals is also very risky, as they might not fulfill the promises and never send back the required decryption tool.

While this might sound terrible, not all is lost – data recovery software might be able to help you in some situations (it highly depends on the encryption algorithm used, whether Wnlu ransomware managed to complete the programmed tasks, etc.). Since there are thousands of different ransomware strains, it is immediately impossible to tell whether third-party software will work for you.

Therefore, we suggest trying regardless of which ransomware attacked your computer. Before you begin, several pointers are important while dealing with this situation:

• Since the encrypted data on your computer might permanently be damaged by security or data recovery software, you should first make backups of it – use a USB flash drive or another storage.
• Only attempt to recover your files using this method after you perform a scan with anti-malware software.

Install data recovery software

1. Download Data Recovery Pro.
2. Double-click the installer to launch it.
3. Follow on-screen instructions to install the software.
4. As soon as you press Finish, you can use the app.
5. Select Everything or pick individual folders where you want the files to be recovered from.
6. Press Next.
7. At the bottom, enable Deep scan and pick which Disks you want to be scanned.
8. Press Scan and wait till it is complete.
9. You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
10. Press Recover to retrieve your files.

The worst thing about ransomware is the fact that malware locks important files and affects performance significantly. You can remove the threat with SpyHunterCombo Cleaner or MalwarebytesMalwarebytes and terminate the activities of the Wnlu file virus. However, note that virus removal is not the same as data recovery. Direct options for decryption are not released, but there are some options still.

Data backups, third-party recovery programs, and decryption tools are the best options. There are various changes that ransomware can take care of to ensure that some of the data functions and security programs are disabled. You can find the particular Safe Mode option below that helps with some of the alterations

As for the general damage and virus-made changes, you still need to double-check before you go for the data recovery tools or options. FortectIntego can help find all the pieces left by the Wnlu file virus. When you know that the ransomware is no longer running on the system, you can be sure that recovered files will not get damaged again.
