Agho Virus Removal Guide (+Decrypt .agho files)

Agho – Ransomware

Agho is a harmful software application functioning as common ransomware. Michael Gillespie, the well-known virus researcher, very first discovered this new name in the DJVU ransomware family.

Agho was developed for the sole function to encrypt all popular file types. Realistically, as quickly as the encryption is effectively accomplished, the users are not able to get access to them. Agho virus adds its own “.agho” to all the encrypted data. For example, the file “price_list.xls”, as soon as crypted by Agho, will be titled as “price_list.xls.agho”. Once the file encryption is accomplished, Agho puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by document asking for the random os really comparable to the notices offered by other ransomware hazards belonging to the DJVU family. The warning basically indicates that the data has been encrypted and the only service to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.

The approach to encrypt the files utilized by Agho is not totally looked into. However, there is no doubt that each computer system owner might be provided an unique decryption key, which is absolutely special. It is very difficult to recover the data without the suitable type in location.

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

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

One more peculiarity of the Agho infection 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 actually released the Agho infection into the web. In order to get the key and bring back the crucial data, the users are told to contact the scams through email or by telegram and to pay the ransom in the amount of $980.

The message likewise says that the people ought to call the Agho authors within 72 hours upon the minute of the data file encryption. The alert indicates that by doing so individuals will acquire a 50% discount rate, therefore, the ransom amount falls to $490.

No matter what the amount of the ransom is, we strongly encourage that you do not pay the ransom. There is no assurance that these online crooks will keep their pledges, so they may not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Hence, paying ransom often does not result in an effective healing. So, the users might just lose their money for nothing.

Likewise, we urge you not to contact the frauds as they instruct. Do not move cash into their wallets. There are no applications that could break the Agho ransomware or restore the information for free. For that reason, the only right decision is to bring back the data from possible backups (if offered).
