How to remove Dharma-Good Ransomware and decrypt .good files

Dharma-Good Ransomware is typical representative of encryption viruses from Crysis-Dharma-Cezar ransomware family. This sample appends .good extension to affected files. Dharma-Good Ransomware adds complex extension, that consists of unique id, developer's e-mail and .good suffix. As a result, file named 1.doc will be converted to 1.doc.id-{8-digit-id}.[{email-address}].good. Dharma-Good Ransomware developers can extort from $500 to $15000 ransom in BTC (BitCoins) for decryption. Usually, it is quite big amount of money, because hackers pay the commission to Dharma Ransomware as Service (RaaS) owners. Using cryptocurrency makes it impossible to track the payee. Besides, victims of such viruses often get scammed, and malefactors don't send any keys even after paying the ransom. We do not recommend to pay any money to malefactors. Usually, after some period of time security specialists from antivirus companies or individual researchers break the algorithms and release decryption keys. Mention, that some files can be restored by using backups, shadow copies, previous versions of files or file-recovery software.

Dharma-MERS Ransomware is another iteration of extremely dangerous Crysis-Dharma-Cezar ransomware family, that, in this case, adds .MERS extension to the end of the files it encrypts. Virus, actually, composes suffix using several parts: e-mail address, unique 8-digit identification number (randomly generated) and .MERS extension. So, finally, encoded files will receive following complex suffix - .id-{8-digit-id}.[{email-address}].MERS. As a rule, Dharma-type Ransomware extorts for $500 to $1500 ransom, that can be paid in Monero, Dash or BTC (BitCoins), and in return they promise to send decryption key. Using cryptocurrency makes it impossible to track the payee. We do not recommend to pay any money to malefactors. Usually, after some period of time security specialists from antivirus companies or individual researchers break the algorithms and release decryption keys. Mention, that some files can be restored by using backups, shadow copies, previous versions of files or file-recovery software.
