Mr-X666 ransomware removal instructions
What is Mr-X666?
Discovered by Michael Gillespie and belonging to the GlobeImposter ransomware family, Mr-X666 is a malicious ransomware-type program that cyber criminals distribute to extort money (cryptocurrency) from innocent people. This is achieved by encrypting files stored on computers and making ransom demands to restore them. This ransomware renames encrypted files by adding the ".Mr-X666" extension. For example, "1.jpg" is renamed by Mr-X666 to "1.jpg.Mr-X666". In addition, Mr-X666 creates a ransom message within a file called "HOW TO BACK YOUR FILES.txt" and places the file in all folders that contain encrypted files.
Within the "HOW TO BACK YOUR FILES.txt" ransom message, cyber criminals inform victims that all files were encrypted, and to decrypt them, they must use a decryption tool. To acquire this tool, they are encouraged to contact the developers of Mr-X666 by sending an email to email@example.com or firstname.lastname@example.org (the email message must include a personal ID). Victims should then receive instructions on how to pay for a decryption tool. They promise to send this as soon as they receive the money. As 'proof' that they have this tool, they offer free decryption of some files, which must also be sent to one of the aforementioned email addresses with the assigned unique ID. Mr-X666's developers assure victims that only they can provide a decryption tool. They urge victims not to attempt to decrypt data using any other tools, since this can supposedly lead to permanent data loss. Unfortunately, that is accurate: only the cyber criminals who developed Mr-X666 can decrypt data encrypted. Most cyber criminals use cryptography algorithms (symmetric or asymmetric) that make encryption 'uncrackable'. In summary, encrypted files cannot be decrypted without using specific tools. Unfortunately, in most cases, only the ransomware developers have the tools capable of file decryption. There is no software available that can decrypt data encrypted by Mr-X666 free of charge (at least not at the moment). Furthermore, people who develop programs such as Mr-X666 cannot be trusted, even if their ransom demands are met. They send no decryption tools and simply ignore victims. Therefore, we recommend that you maintain regular backups and restore all files from there.

Mr-X666 is one of many other programs of this type. Some examples of other ransomware-type programs are CMG, L1LL, and Prus. Most encrypt data and display ransom messages. The main differences between these programs are cryptography used to encrypt files and cost of decryption tool (ransom amount). Typically, decryption without the involvement of cyber criminals is possible only if ransomware is still in development, has unfixed bugs/flaws, and so on. To avoid data loss, maintain regular backups and keep them stored on remote servers (such as Cloud) or unplugged/disconnected storage devices.

To eliminate Mr-X666 virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
To keep computers safe from various infections, do not open attachments or links that are presented in emails received from unknown, suspicious addresses. Generally, they are included in irrelevant emails that are presented as legitimate and official. Additionally, download software from official, trustworthy websites and using direct links. Avoid dubious channels such as torrents, eMule, dubious websites, third party downloaders and other such tools. Installed software and operating systems should be updated using tools or implemented functions that are provided by official developers only. Software activation should not be done using third party ('cracking') tools. They are illegal and can be used to cause computer infections. Keep your computer protected by having reputable anti-spyware or anti-virus software installed and keep it enabled at all times. These programs detect and eliminate various threats before they can do any damage. If your computer is already infected with Mr-X666, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Mr-X666 are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
