Mmpu is a ransomware virus that falls under the file-encrypting subcategory. Mmpu’s creators are using this malware to blackmail attacked users for access to their own files and to extort money from them.

The file-encrypting ransomware attacks are very common today and, unfortunately, there’s still no standardized solution that can help the victims deal with them. That’s why the best thing one could do is to back up their most important files. In this way, they can make sure that the backup data is always available and safe even if ransomware like Mmpu,.Oodt,.Oopu hits the computer.

Sadly, this does not resolve anything if you already have been attacked by a ransomware virus and you have no file backup of the files that have been encrypted. In such a scenario, your only solution is to carefully consider the possible options and choose which one best suits your particular circumstances. In this post, we will try to assist you to our full ability and will provide you with a removal guide that contains a file-recovery section and a section that explains how to remove Mmpu from your computer.

The Mmpu virus

The Mmpu virus is a stealthy infection that can compromise a computer without showing any indications. Once inside, the Mmpu virus can encrypt a range of digital files and then ask the owner to pay a ransom for them.

The hackers behind the ransomware virus typically try to force you to send them some money in order to regain access to your encrypted information. They normally promise to send a unique decryption key in exchange for the money and give their victims instructions on how to make the transfer. The instructions are displayed in a ransom message that the virus will generate once the encryption is applied to the target files. The message generally comes in the form of a notepad file placed on the desktop or inside the folders that contain encrypted files.

When users unexpectedly find that they can no longer access their most important files and a ransom notification is placed anywhere on their computer, they typically get frustrated and don’t know how to act. Please note, however, that it is not advisable to follow the instructions from this notice because security experts alarm that even if you have the money that is required and transfer it to the hackers, there is still no guarantee that you will regain access to your files. Besides, there is no need to fulfill the ransom demands immediately. At least, not until you give a try to some alternative solutions such as the ones described in the removal guide below.

The Mmpu file encryption

The Mmpu file encryption is a stealthy process with the help of which the ransomware virus begins to restrict access to the files on your computer. To make the encrypted files available again, the Mmpu file encryption has to be decrypted with a decryption key which is kept in secret by the hackers.

Users who don’t want to pay for a decryption key or don’t get it from the hackers, however, should not get discouraged. There are some methods that may help them recover some of the encrypted information and we have listed them below. In any case, deleting the ransomware is essential for the health of the infected computer that’s why we suggest you don’t skip the section in the guide that explains how to remove Mmpu and its traces.

Bookmarking this page (the star icon on the upper right corner of the URL bar) is the first preparational step that we recommend you to do as you will need to come back to this page to complete the full removal of Mmpu. 

Then, before you do anything else on the steps, make sure that you boot your computer in Safe Mode . The active link will guide you to another page with instructions about that. Once you complete them, come back to this page to continue with the removal of Mmpu.

Now, enter the Windows Task Manager. It is easiest to use the CTRL + SHIFT + ESC key combination that will immediately display the Task Manager window on your screen. Once it opens, select the Processes Tab. Look at the “Image Name” column and seek processes that seem to be unfamiliar to you or look questionable.  Also, look at the CPU and the Memory tab and see how much system resources these processes are using. This may help you determine which of them are dangerous or could be related to the ransomware infection. 


When you decide that a given process is questionable, right-click it and select Open File Location. Once you get to that location, drag and drop the files found there in the free online virus scanner on this page:

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.

    Run a scan and, if the scanned files turn out to be malicious, go to the Task Manager, and in the Processes tab end the related processes. Then delete the folders that contain the malicious files. 



    When you are done with the instructions in step 2, go to your Desktop and press the Start and R keys from the keyboard together.

    A Run box will pop-up on the screen where you have to  copy and paste this:

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

    Hit the Enter key to run the command that you have pasted. Immediately after that, you should see a simple text file named Hosts on your screen. Head to the Localhost section of the file and check if you see any strange IP addresses there. Use the image below as a guide:

    hosts_opt (1)


    Attention! If you detect suspicious IP addresses below “Localhost” in your Hosts file, please leave us a message in the comments. We will provide you with instructions on what to do in case your computer has been hacked.

    After that, continue with the removal of Mmpu from your system by typing msconfig in the windows search field and pressing the enter button. This will open the System Configurations window on your screen:



    From the tabs that are available, select the Startup tab. Look at the entries there and, especially check those that seem questionable or have a Manufacturer that is “Unknown”. Sometimes, the ransomware may use the name of a fake Manufacturer or hide its processes under the name of a regular system process. Keep that in mind that carefully research all entries on the list. 

    Remove the checkmark before those that seem unreliable and leave only the ones that are legitimate.

    Once you have reviewed the startup entries, it is time to dig into the Registry Editor. Ransomware threats like Mmpu tend to make changes in there and to leave some helper components that need to be deleted. To find all traces of the infection, firstly type Regedit in the windows search field and press Enter. This will open the Registry Editor app. Once it opens, press CTRL and F keys from the keyboard and type the Name of the ransomware in the Find box that pops up on the screen.

    After that, run a search for entries that correspond to that name and delete any results that are found.  

    Attention! Be very careful what you delete because there is a risk of serious system damage if you happen to delete entries unrelated to the ransomware. 

    After you are done with the above, type each of the following lines in the Windows Search Field:

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

    Once you get to the listed directories above, check if anything new has recently been added to them. When you get to the Temp folder, Delete everything that is found there. In case you aren’t sure what needs to be deleted, don’t hesitate to write to us in the comments below this post for assistance.
