Thank FLOOD very much!
With the first link https://id-ransomware.malwarehunterteam.com/index.php?lang=en, I could have solved my big problem. Yesterday, I already referred to id-ransomware.malwarehunterteam.com, www.bleepingcomputer.com but could not solve it, because id-ransomware.malwarehunterteam.com, www.bleepingcomputer.com were not updated .besub. Today, it is very lucky, with your instructions, I retried it and saved the data with the new version of STOPDecrypter v2.1.0.15 that id-ransomware.malwarehunterteam.com, www.bleepingcomputer.com were updated .besub.
Thank you very much again, looking forward to receiving enthusiastic help from you.
Regards!
