BtcKING ransomware removal instructions

What is BtcKING?

Discovered by Michael Gillespie, BtcKING is a ransomware-type virus designed to stealthily infiltrate systems and encrypt most stored files (making them completely unusable). During encryption, BtcKING appends filenames with the "ID [victim's_ID].BtcKING" extension. For example, "sample.jpg" might be renamed to a filename such as "sample.jpg ID X9yTde8gPGru.BtcKING". Once files are successfully encrypted, BtcKING generates a text file ("How To Decode Files.txt") and places a copy in each existing folder.

As with most ransomware, the new text file contains a message stating that data is encrypted and that victims must pay a ransom to restore it. To achieve this, they must first send developers a single selected image file. The image is then decrypted and returned with further payment instructions. The message provides no information regarding the encryption itself. Therefore, it is currently unknown which type of cryptography (symmetric or asymmetric) BtcKING uses. In any case, decryption requires a unique key generated individually for each victim. Furthermore, all keys are stored on a remote server controlled by BtcKING's developers and victims are encouraged to pay a ransom for their release. The cost is not specified - these details are provided via email. In most cases, however, it fluctuates between $500 and $1500, and criminals typically demand payment using a type of cryptocurrency (Bitcoin, Monero, or another). Regardless of the cost, do not pay. Research shows that cyber criminals often ignore victims, once payments are submitted. Therefore, paying typically gives no positive result and users are scammed. We strongly advise you to ignore all requests to contact these people or pay any ransoms.

BtcKING shares many similarities with DBGer, CyberSCCP, Qnbqw, Gw3w, and dozens of other ransomware-type viruses. Although they originate from different developers, all have identical behavior (they encrypt data and make ransom demands). In most cases, size of ransom and type of encryption algorithm used are the only major differences. Most of these viruses employ algorithms that generate unique decryption keys. Therefore, unless the virus is not fully developed or has certain bugs/flaws, restoring data manually without involvement of developers (contacting these people is not recommended) is impossible. Malware such as BtcKING presents a strong case for maintaining regular data backups, however, they must be stored on an unplugged storage device, (e.g., Flash drive, external hard drive or similar) or a remote server (such as Cloud), otherwise backups are encrypted together with regular files.

How did ransomware infect my computer?

Ransomware is proliferated in various ways, however, the most popular five are: 1) trojans; 2) fake software update tools; 3) peer-to-peer [P2P] networks, 4) unofficial software download sources, and; 5) spam emails. Trojans are the simplest of all, since most simply open "backdoors" for other malware to infiltrate the system. Fake software updaters infect the system by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates. P2P networks (torrents, eMule, etc.) and other unofficial download sources (free file hosting/freeware download websites, etc.) present malicious executables as legitimate software. Therefore, users are tricked into downloading and installing malware. Spam emails are delivered with malicious executables (e.g, MS Office documents, JavaScript files, and others). Once opened, these files execute scripts designed to download and install malware. Ultimately, the main reasons for computer infections are poor knowledge and careless behavior.

How to protect yourself from ransomware infections?

The key to computer safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing software. Think twice before opening email attachments. Files that seem irrelevant or have been received from a suspicious/unrecognizable email address should never be opened. Furthermore, download your programs from official sources only, using direct download links. Third party download/installation tools are used to proliferate PUPs, and thus should never be used. Furthermore, keep installed applications up-to-date. To achieve this, however, use implemented update functions or tools provided by the official developer only. It is also strongly advised to have a legitimate anti-virus/anti-spyware suite installed and running. If your computer is already infected with BtcKING, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Text presented in BtcKING ransomware text file :


To recover data you need decryptor.
To get the decryptor you should:
Send 1 test image or text file to
In the letter include your personal ID (look at the beginning of this document).
Attach the file with the location c:\Windows\YOUR KEY.KEY

We will give you the decrypted file and say price for decryption all files
After we send you instruction how to pay for decrypt and after payment you will receive a decryptor and instructions We can decrypt one file in quality the evidence that we have the decoder.

Only can decrypt your files
Do not trust anyone
Do not attempt to remove the program or run the anti-virus tools. You can loss your data
Attempts to self-decrypting files will result in the loss of your data
Decoders for other IDs are not compatible with your ID data, because each user's unique encryption key

Step 2

Log in to the account infected with the BtcKING virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.

If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

system restore using command prompt type cd restore

3. Next, type this line: rstrui.exe and press ENTER.

system restore using command prompt rstrui.exe

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the BtcKING ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining BtcKING 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 BtcKING 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.

Restoring files encrypted by CryptoDefense

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 regain control of the files encrypted by BtcKING, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

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 BtcKING ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
