Uninstall Mmpu virus (Bonus: Decryption Steps)

Description of Mmpu ransomware

Mmpu ransomware is an infection that locks data and tags it with a .mmpu extension

This threat encrypts personal data and demands to pay the ransom.

Mmpu ransomware is a virus that demands money from victims, promising to decrypt files after the money is transferred. The threat has one goal – to bring profit to its creators by scaring people into paying the required ransom. Some people believe the scary ransom message they find in the ReadMe.txt file and contact cybercriminals, but it is not recommended.

An infected computer may receive additional threats if you try to contact cyber criminals. Mmpu file virus is a threat reported by users quite recently, and in this case, there are no decryption tools that can be reliable and useful. Any other measures suggested by anyone but cyber security professionals cannot produce good results.

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

The best decision you can make when you encounter this virus is to remove it. Only after deleting the threat and all associated files can you attempt to restore your data and fix the system.

More information about infection

Mmpu ransomware virus can infect your computer when you open an infected program package of any kind that is already downloaded to your device from pirated platforms. As soon as ransomware enters the system, it immediately begins its activity and encrypts personal data. In addition, the virus may damage or change system files to ensure its smooth operation.

Experts constantly warn about these dangerous infections and inform that e-mails may contain infected file attachments, parts of which may directly trigger malware penetration when the macro feature is enabled. The process is fast and in most cases stealthy, so users don't notice anything at first.

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. The price of decryption is $490 in the first 72 hours, but after that, it doubles to $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.

You cannot know what other threats have been enabled on the device to improve the durability of this ransomware. Threat creators can even use trojans and other malware to distribute Mmpu ransomware. Ignore any criminal messages and claims. The best thing you can do is to get rid of the threat and fix the system.

How to remove the infection

Mmpu ransomware virus needs to be properly removed to completely clean the device and keep all processes under proper control. The threat can create unwanted tasks and other threats to run the ransomware code and lock all newly added files as well.

The best way to deal with this problem is to remove the virus.

Be sure to rely on proper anti-malware tools for the Mmpu file virus removal process to completely terminate the infection. Security programs like SpyHunter 5Combo Cleaner or Malwarebytes can help you find and remove these ransomware-type threats and other dangerous infections. There are various problems that can be caused by a ransomware infection, so it is very important to double-check your system even after you have removed the virus.

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 this threat get removed, and the active virus is no longer running. This helps with a safe file recovery later.

Decryption option

There is an option for some of the versions in this Djvu family – a decryption tool that works with offline ids. You should try using Emsisoft decryptor for Djvu/STOP. It is important to mention that this tool will not work for everyone due to malware methods of encrypting files differently.

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.
