Converton ransomware removal instructions
What is Converton?
Converton is ransomware-type malware that stealthily hijacks computers and encrypts various files. This ransomware employs the AES-256 encryption algorithm with an RSA-2048 key. Thus, two keys (public and private) are generated during encryption. Converton ransomware also adds .converton, .enigma or .czvxce extension to each compromised file. Furthermore, this ransomware creates a !!!-WARNING-!!!.html file on victims' desktops. This file contains all details regarding the encryption.
The message within the !!!-WARNING-!!!.html file states that all files have been encrypted and that the victim must pay a ransom to restore them. Cyber criminals demand 1 Bitcoin (at time of research, equivalent to $413.15). Victims are informed that if the ransom is not paid within the given time frame, the size of ransom doubles. The file also contains step-by-step payment instructions - users are encouraged to install the Tor browser and visit the URL address provided, which supposedly contains further instructions. Research shows that paying the ransom will not help victims restore their compromised files - the decryption method sent to victims after paying the ransom does not work. Therefore, you should never attempt to pay any ransom. Unfortunately, there are currently no tools capable of decrypting files compromised by this ransomware. Therefore, you can only restore the files/system from a backup.
Screenshot of a message encouraging users to contact the developers of Converton ransomware to decrypt their compromised data:
There are many ransomware-type viruses similar to Converton including, for example, Locky, Rokku, Maktub, and Locker. All encrypt victims' files and demand a ransom in exchange for the decryption key/software. The main difference between them is the encryption type and size of ransom demanded. Be aware that most ransomware is proliferated using malicious email attachments, peer to peer (P2P) networks, fake software updates, and trojans. Therefore, be cautious when opening email attachments sent from unrecognized addresses and downloading files/applications from third party sources. Additionally, keep your installed software up-to-date. Using a legitimate anti-spyware or anti-virus suite is also paramount.
Text presented in !!!-WARNING-!!!.html file:
Warning! What happened to you computer?
All your files on herd drives, removable media and network files were encrypted by a cryptographically strong algorithm AES-256 with encryption key RSA-2048.
The expansion of encrypted files is .Coverton
For the time the decryption of AES-256 is impossible.
What have you to do?
To receive a pair of keys for decrypting your files you have to of through the following steps:
Simple variant: click to http://Inc57humvaxpqfv3.onion.to/ and follow the instructions OR complex variant:
1. Download TOR Browser: https://www.torproject.org/download/
2. Open link it TOR Browser http://Inc57humvaxpqfv3.onion/
3. Follow the instructions.
We recommend you not to disconnect your computer from the electrical supply.
We recommend you not to disconnect your computer from the Internet.
We recommend you not to extract the encrypted electronic data carriers.
Do not try to cheat the system, do not attempt to edit encrypted files, do not attempt to remove the program.
Such actions can easily bring to the inability to recover your files and data, so we can not help you.
The key to decrypt your files is stored on our remote server.

Converton ransomware removal:
Instant automatic malware removal:
Manual threat removal might be a lengthy and complicated process that requires advanced computer skills. Malwarebytes is a professional automatic malware removal tool that is recommended to get rid of malware. Download it by clicking the button below:
- What is Converton?
- STEP 1. Converton virus removal using safe mode with networking.
- STEP 2. Converton ransomware removal using System Restore.
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup. Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings". Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

Log in to the account infected with the Converton 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.
Video showing how to remove ransomware virus using "Safe Mode with Command Prompt" and "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.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
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 Converton ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Converton 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 Converton 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 encrypting ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and Malwarebytes Anti-Ransomware, which artificially implant group policy objects into the registry to block rogue programs such as Converton ransomware.)
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
