Remove Dragon Ransomware (.locked Files)

To decrypt files infected with Dragon (.locked) ransomware, please use the official and free tool offered by Emsisoft website.

Dragon ransomware is described by malware researcher as a type of computer virus that encrypts files on the infected system and simultaneously adds a .locked extension into them. According to reports, this virus appears to be a variant of Aurora and can be executed selectively via geographical location. Surprisingly, Dragon virus will not execute if it detects that the victim is located in Hong Kong, China, or Taiwan.

Aside from this geographical exception, Dragon ransomware operates normally as other crypto-virus currently in the wild. It is clever in selecting which file to encrypt using an advanced technique. Obviously and similar with most ransomware type, Dragon’s objective is to deny user’s access to their own data and exploit this situation to demand money transfer in exchange for private key and decryption software. As shown in the screenshot image below, the pricey tool costs more or less US $3,000 if converted from 0.3 Bitcoin.

Fortunately, victims of this specific Aurora variant do not have to settle with cyber crooks, as there is already available free Dragon decryption software. We give credits to the hard work of Emsisoft and malware researcher Michale Gillespie for producing this recovery application in no time. Proceed to the recovery section below to download the tool and start restoring all .locked files to previous original format.
