CryptoDevil ransomware removal instructions

CryptoDevil ransomware removal instructions

What is CryptoDevil?

CryptoDevil is a ransomware-type virus discovered by malware researcher, xXToffeeXx. After infiltrating the system, CryptoDevil stealthily encrypts various files. Unlike other ransomware-type viruses, however, this virus only encrypts files stored within the CryptoDevil folder (and subfolders). In addition, CryptoDevil appends names of encrypted files with the ".devil" extension (e.g., "sample.jpg" is renamed to "sample.jpg.devil"). Following successful encryption, CryptoDevil opens a pop-up window that contains a ransom-demand message.
As compared to other similar viruses, CryptoDevil's message is short and merely states that files are encrypted and that the victim must pay to restore them. It is currently unknown whether CryptoDevil uses symmetric or asymmetric cryptography - in any case, decryption without a unique key is impossible. Cyber criminals store this key on a remote server and attempt to blackmail victims to receive it. The cost of CryptoDevil decryption depends on how soon victims pay, and fluctuates between $20 and $100. If, however, the ransom is not paid within 82 hours, the key is permanently deleted, making it impossible to restore encrypted files. Be aware, however, that paying does not guarantee that your files will ever be decrypted and there is a high probability that criminals will ignore you. Therefore, never attempt to contact these people or pay any ransom. Unfortunately, there are no tools capable of restoring files encrypted by CryptoDevil. This problem can only be resolved by restoring files/system from a backup.

CryptoDevil has similar characteristics to dozens of other ransomware-type viruses such as ZinoCryptRozaLockerRevenge, and Karmen. All encrypt files and makes ransom demands. There are just two major differences: 1) type of encryption algorithm [symmetric/asymmetric] used, and; 2) cost of decryption. Cyber criminals often proliferate ransomware by employing fake software update tools, trojans, spam emails (malicious attachments), and third party software download sources (torrents, eMule, freeware download websites, free file hosting websites, etc.) Therefore, keep your installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite. Furthermore, never open files received from suspicious emails or download software from unofficial sources. Rushing and careless behavior is often the reason for computer infections. The key to computer safety is caution.

2. After 24 Hours Key Price = $30
3. After 48 Hours Key Price = $50
4. After 72 Hours Key Price = $100
After 82 hours if you do not buy the key your files will be encrypted for the rest of your life.

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 CryptoDevil 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 CryptoDevil 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 CryptoDevil 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 regain control of the files encrypted by CryptoDevil, 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 CryptoDevil ransomware.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
