The CryptoDevil is a Trojan Horse that will display a “Your Computer Has Been Locked” prompt instead of your normal Windows desktop.
The CryptoDevil is distributed through several means. Malicious websites, or legitimate websites that have been hacked, can infect your machine through exploit kits that use vulnerabilities on your computer to install this Trojan without your permission of knowledge.
The CryptoDevil may also be downloaded manually by tricking the user into thinking they are installing a useful piece of software, for instance a bogus update for Adobe Flash Player or another piece of software. The CryptoDevil is also prevalent on peer-to-peer file sharing websites and is often packaged with pirated or illegally acquired software.
When a computer is infected, the CryptoDevil displays a lock screen when you start Windows which will state that the victim’s files are being deleted unless 0.3 bitcoins are sent to an bitcoin address. The malware developers state that once they verify the payment the computer will automatically be unlocked and you will be able to access your Windows desktop again.
While the text in these messages can be scary, the good news is that the CryptoDevil will not delete or encrypt any files, and can be removed without paying the ransomware.
The text of the CryptoDevil screen locker is:
Your Computer Has Been Locked Your computer have been successfully locked you have up to 70 hours
to buy a key to unlock your contract in case files will be deleted.
Email: mutr0lblackhat@gmail.com
Payment: Bitcoin 20
When the “kjkszpj” pass code is entered, the alert that is shown will contain this text:
Instruction! How To Remove my virus
1. Open Start Menu
2. Go to Startup
3. Delete CryptoDevil.exe End!

How to remove “CryptoDevil” lock screen (Removal Guide)
- STEP 1: Remove the CryptoDevil lock screen
- STEP 2: Use Malwarebytes Anti-Malware to remove CryptoDevil malware
- STEP 3: Double-check for malware with HitmanPro
STEP 1 : Remove the CryptoDevil lock screen
In this first step we will remove the “CryptoDevil” lock screen from Windows.
Because there are many versions of this malware, which behave differently, we have provided multiple options to remove the malicious lock screen.
OPTION 1: Remove the malicious lock screen with HitmanPro.Kickstart
HitmanPro.Kickstart is the solution against ransomware and other persistent malware that has taken your computer hostage or prevents normal computer use.
Because this infection has locked you out of your computer, we will need to create a bootable USB drive that contains the HitmanPro.Kickstart program. We will then boot the infected machine with the HitmanPro.Kickstart USB drive, and use the program to clean the infection.
- Using a “clean” (non-infected) computer, please download HitmanPro from the below link.
HITMANPRO DOWNLOAD LINK (This link will open a new web page from where you can download “HitmanPro”) - Once HitmanPro has been downloaded on the clean machine, insert an USB flash drive and double-click on the file named HitmanPro.exe (for 32-bit versions of Windows) or HitmanPro_x64.exe (for 64-bit versions of Windows).
To create a bootable HitmanPro USB drive, please follow the instructions from this video:
- Once you have created the bootable HitmanPro.Kickstart USB drive, insert the USB into the computer infected with the “CryptoDevil” lock screen.
- After you have inserted the HitmanPro Kickstart USB drive, boot your machine from the HitmanPro.Kickstart USB as seen in the below video.
- The malicious lock screen should be removed from your machine. It’s recommended that you perform a system scan with Malwarebytes and HitmanPro as see in the below steps.
OPTION 2: Start your computer in Safe Mode with Networking
If the above options did not work for your machine, then we will need to start the computer in Safe Mode with Networking to bypass the lock screen.
- Immediately after the computer is powered on or restarted (usually after you hear your computer beep), tap the F8 key in 1 second intervals.
- After your computer displays hardware information and runs a memory test, the Advanced Boot Options menu will appear.
- Use the arrow keys to select Safe Mode with Networking and press ENTER.
- After you have started your machine in Safe Mode with Networking, run a system scan with Malwarebytes Anti-Malware as seen in the below step.
STEP 2: Scan your computer with Malwarebytes Anti-Malware
