Matu is a criminal cyber tool used for the purposes of money extortion – it locks the files of its victim and won’t release them until a payment is made. Matu typically requests the payment in BitCoin or another similar cryptocurrency so that its creators could retain their anonymity.

The Matu virus file ransom note

Matu is a very nasty Ransomware infection, which can secretly encrypt all of your personal files and ask you to pay ransom to some anonymous hackers. The infection operates in stealth and is usually capable of remaining under the radar of most security programs, which make its attack very surprising and unexpected. To additionally worsen the situation, Matu Virus displays a scary ransom-demanding notification on the screen of its victims which claims that if they don’t transfer the required ransom money, they will lose access to their valuable files forever. It is a popular practice that a deadline is given to the affected users and unless the demanded ransom is paid off within the mentioned time interval, the encrypted files would most likely continue to be locked indefinitely. A specific thing that additionally contributes to the performance of Ransomware blackmailing is the fact that the money is often requested not in regular currency but in cryptocurrency such as bitcoins. The particular reason why the use of bitcoins is important is that this cryptocurrency is almost impossible to track, which, respectively, makes it possible for the blackmailer to stay hidden and without fear of getting caught. This way, if you transfer the requested ransom, you can’t uncover the cybercriminals in an attempt to get your ransom back. Thus, if you have been infected by Matu , Maos or Manw and you are thinking to transfer the ransom, know that regardless of whether you actually receive the decryption details for your files or not, your money would be gone permanently. Moreover, many users aren’t given any solution that can get their encrypted files back even after paying, anyway.

The Matu virus

The Matu virus is a malicious computer virus that is used as a money-extortion tool. The Matu virus will deny all access to your most valuable files until a ransom payment is made to the hackers behind it.

The Matu file

The Matu file is a type of encrypted file that this virus creates after it launches its encryption process on the infected computer. The Matu file is an identical copy of a user file with the only difference being that it is encrypted and can’t be accessed without the correct key.

Remove Matu Ransomware

As a first step, be sure to save these Matu removal instructions to your browser’s bookmarks. In this way, you won’t have to search for the Matu removal guide after the system restarts that follow.

A Safe Mode restart will let you see what programs are currently running in the background of the system and will hopefully make it easier to detect and deal with Matu and its malicious processes. That’s why, we recommend you to restart the system with the help of the instructions from the link and then get back to the guide and proceed to step two.

The second step involves launching the Task Manager by hitting CTRL, SHIFT, and ESC at the same time on your keyboard. In the Task Manager, look at the Processes tab to find out what processes are using up a lot of system resources. Right-click on any process that looks suspicious and select Open File Location from the context menu that comes on the screen to check the files linked with it.

All files connected with that process should then be scanned for harmful code using a powerful scanner. This guide includes a link to a free virus scanner that you may use for that purpose.

    Before deleting the files the scanner has flagged as dangerous, go to the Task Manager, right-click on the suspicious process and choose End Process from the context menu to stop it from running. After that, go to the File Location folder and delete the dangers that the scanner has detected.

    The Hosts file on a computer is a common target that may be modified by an attacker after the system has been hacked. Therefore, the next step is to manually check the file for IP addresses that may be troublesome (like those on the image below). You may access the Hosts file on your computer by simultaneously hitting the Windows key and R and pasting the following command into the box labeled Run:

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

    After that, search for “Localhost” in the text of the file and look for any weird IP addresses. Please use the comment box given below if you see anything suspicious about the IPs that you discover. In case that we determine that the IP addresses you’ve detected are malicious, we will come back to you with some advice on how to proceed.


    Using the Windows Search bar, enter “msconfig” then press Enter. This step will open the “System Configuration” window on your screen. Start-up-related items are listed in this window under the “startup” tab. Take a look at the items listed there and, if needed, remove any checkmarks from the items you think are linked to the ransomware. This will disable them and stop them from starting the next time the system restarts. Click “OK” to save your changes after that.

    More and more malicious programs are secretly adding harmful entries to the computer’s registry in order to avoid detection and continue to function for as long as possible after being installed on the machine. Therefore, in this step, you need to use the Registry Editor to find and delete any files linked with Matu that were installed on your computer without your knowledge. This will help you to fully remove the traces of the ransomware from your computer. To do that, in the Windows search bar, type regedit, and then click the Enter key on your keyboard to open the Registry Editor.

    Pressing CTRL and F at the same time will allow you to search for files that may be related to the malware. Entering the name of the threat in the Find box that appears will help you search for it. Choose the Find Next button from the Find box to begin searching for malicious files. 

    Attention! Please be cautious while removing any files that appear in the search results! The risk of accidentally deleting non-malicious registry files should be considered before attempting to manually remove the registry files connected with the infection. In case you need help, an antivirus software (such as the one on this page) is your best bet when it comes to protecting your computer from potentially hazardous apps and dangerous registry entries.

    Ransomware files may be stored in the following five computer locations. That’s why, we recommend you go through each of them and carefully check them for any unusual or recently added files. To do that, you’ll need to use the Windows Search bar and type in each of the following search phrases:

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

    Look for files that may contain harmful code, but don’t make any changes or remove anything unless you’re confident in your actions. To delete any temporary files in your computer’s Temp directory, hold down the CTRL and A keys and then hit the Delete key on your keyboard.

    How to Decrypt Matu files

    Trying to decode ransomware-encrypted data is difficult for non-ransomware experts. Decryption methods might vary based on the variant of ransomware that was used to encrypt the data, making it more difficult to get it back. Ransomware variants may be identified by looking at the file extensions that are appended to the encrypted files.

    Before you begin the process of data recovery, however, you must first do a thorough check of your computer using an anti-virus program (like the one offered on our website). It’s safe to look at the file recovery solutions available to you only after you’ve conducted a complete virus scan and found none.

    Next Djvu Ransomware

    A new variant of ransomware known as STOP Djvu ransomware is the source of disturbance for a lot of users and security experts globally. This malware often adds the extension .Matu at the end of the encrypted files. The good news is that decryptors like this one below may be able to help you retrieve your encrypted data in the event that you’ve been affected by this threat:

    To begin decrypting the files, you must first run the STOPDjvu.exe program that has been downloaded to your computer. Upon downloading the file, choose “Run as Administrator” and then press the “Yes” button to proceed. Read the license agreement, together with any accompanying instructions, thoroughly. The program may not be able to decrypt data encrypted using unknown offline keys or online encryption techniques, so be aware of that.

    Our website has anti-virus software that can help you remove the Matu ransomware if you’re having problems with that. Alternatively, you may use our free online virus scanner to do a manual scan on any files you suspect may be dangerous.
