Agvv – Ransomware

Agvv was created for the sole function to encrypt all popular file types. Realistically, as quickly as the file encryption is effectively accomplished, the users are not able to get access to them. Agvv virus includes its own “.agvv” to all the encrypted data. For example, the file “price_list.xls”, when crypted by Agvv, will be titled as “price_list.xls.agvv”. Once the encryption is achieved, Agvv puts its own unique text document (_readme.txt) into all the folders that store the encrypted files.
The alert mentioned by document requesting the random os extremely comparable to the notices offered by other ransomware hazards belonging to the DJVU family. The warning generally shows that the information has been secured and the only service to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely true.
The method to secure the files used by Agvv is not totally investigated. However, there is no doubt that each computer system owner might be released a special decryption key, which is absolutely unique. It is exceptionally hard to recuperate the information without the suitable key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Agvv virus is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have launched the Agvv infection into the world wide web. In order to obtain the key and bring back the essential information, the users are informed to connect with the frauds through e-mail or by telegram and to pay the ransom in the amount of $980.
