Maiv Virus Removal Guide (+Decrypt .maiv files)

Maiv – Ransomware

Maiv is a harmful software working as common ransomware. Michael Gillespie, the popular virus researcher, very first found this new name in the DJVU ransomware family.

Maiv was created for the sole function to encrypt all popular file types. Logically, as soon as the file encryption is successfully accomplished, the users are unable to get access to them. Maiv ransomware adds its own “.maiv” to all the encrypted data. For instance, the file “price_list.xls”, when crypted by Maiv, will be titled as “price_list.xls.maiv”. As soon as the encryption is accomplished, Maiv puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The alert mentioned by _readme.txt requesting for the random os really comparable to the notifications offered by other ransomware hazards coming from the DJVU family. The caution generally indicates that the files have been encrypted and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.

The method to secure the files used by Maiv is not completely investigated. However, there is no doubt that each computer owner might be issued a special decryption key, which is definitely distinct. It is incredibly hard to recuperate the data without the suitable key in place.

“Don’t worry, you can return all your files!”, from text file message:

Don't worry, you can return all your files! virus

One more peculiarity of the Maiv infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have actually introduced the Maiv virus into the world wide web. In order to acquire the key and restore the important data, the users are informed to contact the frauds through email or by telegram and to pay the ransom in the amount of $980.

The message also states that individuals must contact the Maiv authors within 72 hours upon the minute of the data file encryption. The alert suggests that by doing so individuals will obtain a 50% discount rate, therefore, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we highly advise that you do not pay the ransom. There is no assurance that these online criminals will keep their promises, so they may not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. Hence, paying ransom typically does not lead to a successful healing. So, the users might simply lose their money for absolutely nothing.

Likewise, we advise you not to get in touch with the scams as they instruct. Do not move money into their wallets. There are no applications that might crack the Maiv virus or bring back the information at no charge. For that reason, the only appropriate decision is to restore the data from possible backups (if readily available).
