Eyrv Virus Removal Guide (+Decrypt .eyrv files)

Eyrv Virus Ransomware

Eyrv is a destructive software application working as typical ransomware. Michael Gillespie, the widely known malware researcher, very first found this new name in the DJVU ransomware family.

Eyrv was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is successfully accomplished, the users are not able to get access to them. Eyrv ransomware includes its own “.eyrv” to all the encrypted data. For example, the file “price_list.xls”, when crypted by Eyrv, will be entitled as “price_list.xls.eyrv”. When the encryption is accomplished, Eyrv puts its own special text file (_readme.txt) into all the folders that store the encrypted files.

The message stated by text file requesting for the random os extremely similar to the alerts offered by other ransomware dangers belonging to the DJVU family. The warning basically shows that the files have been secured and the only service to get access to it is to use a distinct standalone key. Regretfully, this declaration is definitely real.

The technique to encrypt the files used by Eyrv is not totally researched. Nevertheless, there is no doubt that each computer system owner might be issued an unique decryption key, which is absolutely unique. It is incredibly tough to recuperate the information without the suitable type in location.

“Don’t worry, you can return all your files!”, from _readme.txt message:

One more peculiarity of the Eyrv virus is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have released the Eyrv ransomware into the internet. In order to obtain the key and bring back the crucial data, the users are informed to connect with the frauds by means of e-mail or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that individuals ought to contact the Eyrv authors within 72 hours upon the moment of the information file encryption. The alert suggests that by doing so the people will get a 50% discount, therefore, the ransom amount falls to $490.

No matter what the amount 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 file encryption, even when the amount of the ransom is received into their accounts. Hence, paying ransom typically does not result in an effective healing. So, the users might just lose their money for absolutely nothing.

Likewise, we urge you not to contact the scams as they instruct. Do not move money into their wallets. There are no applications that might break the Eyrv virus or bring back the data at no charge. Therefore, the only correct choice is to bring back the information from possible backups (if available).
