How to remove Mmpu ransomware

Mmpu file virus is the type of virus that locks data and makes false claims to get money from victims

Mmpu ransomware virus is affecting machines silently, and it sneaks into computers when users are using torrents or simply just opens emails. The threat is spread using malicious file attachments and parts of the pirating packages, so people can only notice the threat once files are already locked. 

Mmpu ransomware is a dangerous virus that can damage the operating system and lock users' personal files, like photos, videos, or documents. It belongs to Djvu malware family, which releases new variants weekly, and we previously wrote about other similar infections such as Qqpp, Qqjj, and many more.

Once the threat is done with the encryption^[1] process, the infection marks those files using .mmpu appendix. The threat directly affects commonly used files, but there are issues created by the virus when settings get altered, and the system data is corrupted or damaged to keep file recovery and virus removal options limited.

Details about the infection

The _readme.txt file is generated on your machine after the encryption process has finished, and here you can find out what conditions cybercriminals put forth for payment of their ransom. Cybercriminals are always coming up with new ways to extort money from people.

The price of decrypting these threats is $490 in the first 72 hours, but after that, it doubles and eventually going to reach $980 in Bitcoin. It is not advised to consider paying criminals because cyber crime developers usually demand payment by cryptocurrency but do nothing after that, and the Mmpu file virus remains damaging the machine.

There are many ways for you to get your files back, but it's important not to contact these people because they can't be trusted. They might take advantage of vulnerable individuals who don't know any better, and then once payment has been made with cryptocurrencies, the support is not available.

Trying to decrypt the 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.

Spreading ways of the ransomware

Malicious code is usually introduced by an executable file (.exe) that may have been in a zip folder, embedded within Microsoft Office documents' macros, or disguised as another attachment. The threat actors use these tactics to spread Mmpu ransomware across different platforms and organizations.

Malicious files can sneak into your system during cracked software installations too. Platforms that distribute them, like torrent websites and peer-to-peer file sharing platforms, are unregulated – this makes it easy for hackers to spread malware around the internet with little oversight or accountability.

Almost every download usually contains some kind of malicious code that is hard (if not impossible)to identify by just looking at its size alone. Even experts^[2] don't always know what's safe without running an analysis on whatever program we're downloading from first. Pay close attention to details to avoid infections like the Mmpu file virus.

Removing the infection

Mmpu ransomware is a serious infection that should be removed properly from the machine as soon as the infection presents itself. The task is difficult but possible because threats like this can be detected and removed with the help of anti-malware tools.^[3]

The threat can be hidden, and there are various issues that the infection creates, so it is crucial to do the removal process properly. Mmpu file virus removal is the best when you run an antivirus tool like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes and make sure to scan the machine fully. This is the process that helps to improve performance significantly.

Try to check the machine a few times before moving on with file recovery. Antivirus tools can indicate all programs and files that are possibly malicious or dangerous. Trigger the proper scan of the system so all files related to the Mmpu ransomware virus get removed, and the active virus is no longer running. This helps with a safe file recovery later.

System file 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 reinstall 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.

Cybercriminals are always coming up with new ways to get your information, and they use email too! Email messages can be used by hackers in two different ways; one is when you receive an attachment (like viruses) which means that if it looks suspicious, then don't open them.

Keeping your computer up-to-date is a must if you want to avoid becoming part of the hackers' victims. Software developers release security updates for newly found vulnerabilities on an ongoing basis, so installing them as soon as they come out will help keep you safe from any potential attacks by malicious programs.

Mmpu ransomware can spread quickly, so if you become a victim of the threat, you need to remove the threat using proper anti-malware tools that can be considered advanced security software. Anti-malware tools should be chosen wisely, so make sure that the app can run the full system scan and improve its performance.
