Remove Mifr Ransomware

What does it happen when the Mifr ransomware infect a PC? Find out more about the risks of keeping this software on your machine and learn how to fully get rid of its malicious instances.


Mifr Ransomware

The Mifr ransomware is a malicious software based on the code of another ransomware called VoidCrypt. As a cryptovirus, Mifr invades operating systems via shady methods of distribution. Once its activation file is executed on a computer system, the latter’s security gets totally compromised. Since the virus attempts to hide its presence, it may fulfill the attack without you noticing anything wrong.

The moment Mifr virus ends all attack stages it informs its victims about its presence on the system. Unfortunately, at that point, all valuable files are compromised by the threat. Their names are different versions of the original ones. A set of three malicious extensions will be appended to the original names. All .[Hiden_pro@aol.com][ID].mifr files will remain inaccessible until its code is reverted back to its original state.

Another way of Mifr ransomware to uncover its presence on the PC is the display of a ransom note. The note is also stored somewhere on the system. The file is called !INFO.HTA. We strongly suggest that you refrain from following the instructions provided by this message and continue with this thorough ransomware removal guide.

Mifr Virus – More Information

Mifr Virus, a strain of VoidCrypt ransomware acts in a similar way to its predecessors. Some names of previous ransomware infections based on the same threat are Honor virus, Foo virus, and Horizon virus.

The tricky part about infections like Mifr ransomware is that they infect PCs via shady techniques. These techniques enalbe them to run on computer systems without being noticed. Well-know for the delivery of malicious software are spam emails that feature malicious attachments, dangerous ads, freeware installers, and hacked websites.

The execution of this ransomware on a computer operating system enables it to perform a highly complex infection flow. During the attack, it disrupts system security, corrupts essential system components, and eventually encrypts personal files.

Encoded by this ransomware may be all your images, documents, archives, projects, presentations, videos, audio files, as well as all other files that are likely to store valuable information. You probably found out that corrupted files are all marked with three malicious extensions:

  • .[Hiden_pro@aol.com][ID].mifr
  • Ransomware is one of the nastiest computer programs due to the fact that it tends to use sophisticated cipher algorithm to encode personal files. Mifr is not an exclusion from that rule. It leaves .mifr files completely out of order.

    The primary purpose of ransomware threats is to extort a ransom payment from victims. So once the virus encodes target files it will drop a specific ransom note. That note is named !INFO.HTA and it informs the following:

    !!! Your Files Has Been Encrypted !!!♦ your files has been locked with highest secure cryptography algorithm ♦
    ♦ there is no way to decrypt your files without paying and buying Decryption tool♦
    ♦ but after 48 hour decryption price will be double♦
    ♦ you can send some little files for decryption test♦
    ♦ test file should not contain valuable data♦
    ♦ after payment you will get decryption tool ( payment Should be with Bitcoin)♦
    ♦ so if you want your files dont be shy feel free to contact us and do an agreement on price♦
    ♦ !!! or Delete you files if you dont need them !!!
    ♦Your ID :-
    our Email :Hiden_pro@aol.com
    In Case Of No Answer :Hiden_pro@tutanota.com

    Beware that there is no information that declares the Mifr decrypter being efficient so far. So paying the ransom may not guarantee the recovery of your .mifr files.
