bitcoin666 ransomware removal instructions
What is bitcoin666?
Discovered by MalwareHunterTeam, bitcoin666 is one of many ransomware-type programs on the internet. Cyber criminals use bitcoin666 to prevent victims from accessing their files (by making the data unusable). To recover their files, victims are encouraged to pay the developers a ransom. This malicious program renames each encrypted file by adding the ".email@example.com" extension. For example, "1.jpg" becomes "firstname.lastname@example.org". A ransom message in a text file called "Recover Files.TXT" can be found in each folder that contains encrypted files. Furthermore, bitcoin666 changes the desktop wallpaper.
The ransom message states that victims can only regain access to their files by paying cyber criminals .3 Bitcoin into the Bitcoin wallet address provided. If payment is not paid within 24 hours, the cost of decryption increases to .4 Bitcoin. Before paying, it is possible to send a file (no larger that 5 MB) to bitcoin666's developers. They will then decrypt the file free of charge as so-called 'proof' that they have decryption tool. To contact cyber criminals, victims are encouraged to use the email@example.com or firstname.lastname@example.org email address. They also warn victims not to try to decrypt files using another decryption tool. They state that this might cause permanent data loss. Generally, only cyber criminals (ransomware developers) can provide victims with decryption tools or keys. The ransomware-type programs use encryptions that can be decrypted using tools held only by them. Despite this, do not pay these cyber criminals. They send no decryption tools, take the ransom money, and then simply ignore victims. There is no free way to decrypt files encrypted by bitcoin666, at least not at the moment. Therefore, we recommend that you use data backup (if one has been created) and restore files from there.

Ransomware-type programs are usually very similar - most are used to encrypt files and keep them locked unless a ransom is paid. Some examples of other programs of this type are MegaLocker, Langolier, and Etols. Main differences are usually cost of decryption and cryptography algorithm (symmetric or asymmetric) used to encrypt files. Unfortunately, most victims are forced to contact cyber criminals, since ransomware-type programs are impossible to 'crack' without using tools held only by them. They can be cracked without the involvement of ransomware developers only if a program is not fully developed, has bugs/flaws, and so on. To avoid data loss in future, maintain data backups and store them on remote servers or unplugged storage devices.

How to protect yourself from ransomware infections?
Files attached to emails received from unknown/suspicious addresses and presented in an irrelevant message should not be trusted. All software should be downloaded from official websites and using direct links. Other sources mentioned above should not be used. Installed programs or operating systems should be updated via tools or implemented functions that are provided by official software developers only. If installed software is not free of charge, it should be activated properly - use of 'cracking' tools is a cyber crime and also leads to installation of malicious programs. Have reputable anti-virus or anti-spyware software installed and keep it enabled at all times. These tools can prevent computer infections with viruses. If your computer is already infected with bitcoin666, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining bitcoin666 ransomware files.
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 bitcoin666 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.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as bitcoin666 ransomware.
