The contents of this ransom note is slightly different from previous versions of this malware. Unfortunately, files encrypted by GandCrab v5.1 Ransomware are currently not decryptable. However, as some of the previous versions had decryptor from BitDefender, we will provide download link for this tool below.

Monro Ransomware is subtype of Crysis-Dharma-Cezar ransomware family, that adds .monro extension to encrypted files. Virus uses composite extenion, that consists of e-mail adress and unique 8-digit identification number (randomly generated). Monro Ransomware developers extort from $500 to $1500, that have to be paid in Monero, Dash or BTC (BitCoins) for decryption. Due to the fact, that hackers often do not send decryption keys, or just ignore e-mails from victims, who paid the ransom, it is not recommended to send any funds. Usually, after some time security specialists and individual researchers break the algorithm and release master key. Also, some files can be recovered by using backups, recovery software and instructions given on this page.
Scarab-Enter Ransomware is one of the varieties of Scarab Ransomware family. Scarab Ransomware has typical malicious activity: it encrypts user files using AES encryption and demands ransom of 0.3 BitCoins for decryption. Virus-extorsionist appends .enter or .lol extensions to encrypted files. Depending on version, after encryption Scarab Ransomware creates text files HELP HELP HELP.TXT or HOW TO RECOVER ENCRYPTED FILES.TXT text files with instructions to pay the ransom.

There are a lot of reports from the victims, that malefactors don't send decryptors. If Dr. Web Decryption Service fails for you, try manual instructions on this page and file-recovery software. In most cases this helps to restore some important files. In this article we collected, consolidated and structured available information about this malware and possible ways of removal and decryption.
Evolution Ransomware is new ransomware with currently unknown genealogy. There are some indications, that it is based on hte code of Everbe 2.0 Ransomware. Virus encrypts user's files using AES encryption algorithm and adds .evolution extension to encoded files. After contacting the developers via one of the provided e-mails, they demand 2 BitCoins for decryption and offer to decrypt 1 file for free as a proof. After this they send wallet for sending funds. 2 BitCoins at the time of righting this article had equivalent of $8000. We do not recommend paying the ransom as there is no guarantee malefactors will send final decryptor. Currently, there are no decryption tools available for this type of crypto-virus. The only way to get all files back is to restore from backups. You can also try to use instructions and tools below to recover some important files.

Combo Ransomware uses AES-256 encryption, which makes the victim's files inaccessible without decryption key. As for today, decryption is not possible, however, you can attempt to decrypt files from backups or trying file recovery software. There is also chance of decryption after using methods explained in this article.
RYUK Ransomware is virulent ransomware threat, based on the code of Hermes 2.1 and BitPaymer viruses. Researchers believe, that famous Lazarus Group is responsible for the development and implementation of the virus. Latest variations of this virus append .RYK or .rcrypted extension to encrypted files. Hackers demand 15-50 BTC for decryption, which is great amount. RYUK Ransomware does not bypass UAC, requires permission to run, which means user granted access to the computer for virus executable file. Ransomware encrypts all files except ones in following folders: "Windows", "Mozilla", "Chrome", "RecycleBin", "Ahnlab". Before the onset of destructive activity, malware stops more than 180 services and 40 processes, by using taskkill and net stop commands. Stopped services and processes mainly belong to antivirus software, running databases, software for backup and editing documents that can prevent file encryption.
