.kjh Files Virus (Dharma Ransomware) – Distribution and Impact
As identified by security experts the so-called .kjh files virus belongs to the infamous [wplinkpreview url=”https://sensorstechforum.com/beets-files-virus-dharma-remove/”] Dharma ransomware family. Dharma ransomware is a typical cryptovirus that infects computer systems with the primary goal to reach and encode personal files. The most notable trait of infection with this Dharma ransomware strain is the appearance of the extension .kjh after the names of valuable files.
Since the ransomware is designed to encode target files with the help of sophisticated cipher algorithm, once it corrupts them they appear to be completely out of order. The truth is that their information could be accessed after a decryption process that recovers their code to its original state.
To extort a ransom fee for a specific decryption tool .kjh files virus drops a ransom message that reads the following:
All FILES ENCRYPTED “RSA1024”
All YOUR FILES HAVE BEEN ENCRYPTED!!! IF YOU WANT TO RESTORE THEM, WRITE US TO THE E-MAIL datareturn@protonmail.com
IN THE LETTER WRITE YOUR ID, YOUR ID ********
IF YOU ARE NOT ANSWERED, WRITE TO EMAIL: datareturn@protonmail.com
YOUR SECRET KEY WILL BE STORED ON A SERVER 7 DAYS, AFTER 7 DAYS IT MAY BE OVERWRITTEN BY OTHER KEYS, DON’T PULL TIME, WAITING YOUR EMAIL
FREE DECRYPTION FOR PROOF
You can send us up to 1 file for free decryption. The total size of files must be less than 1Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)
DECRYPTION PROCESS:
When you make sure of decryption possibility transfer the money to our bitcoin wallet. As soon as we receive the money we will send you:
1. Decryption program.
2. Detailed instruction for decryption.
3. And individual keys for decrypting your files.
!WARNING!
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.
Apparently, this message aims to persuade you to contact hackers at datareturn@protonmail.com so that they could send you back more details on the ransom payment process. Beware that they could fool you into paying for a broken decryption tool that cannot recover .kjh files or even skip answering you once you transfer them the ransom.
So be advised to keep up with our step-by-step removal guide to remove malicious files from the infected system and attempt to recover files encrypted by this ransomware.
Currently, samples of this threat are lurking around the web. Guesses are that the spread is realized mainly via malspam campaigns. Malspam enables hackers to deliver malicious code on users’ devices with the help of massive email campaigns. Spam emails which are part of attack campaigns usually contain one or more of the following components:
- A link to compromised web page that is set to download and execute infection files directly on the PC. The URL address to this page may be presented in the form of an in-text link, banner, image, button or full URL address.
- A malicious file attachment that is presented as legitimate document by the text message. It could be uploaded in a .rar or .zip archive. Such a file could be set to evade active security measures and trick you into running the ransomware on your PC.
Once started on a computer system .harma ransomware attempts to evade detection by running specific checks for active security measures. When ready, it initiates a long sequence of malicious operations that affect the settings of some essential system components and enable it to encrypt target files.

Step 2: Uninstall .kjh and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by .kjh on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by .kjh there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove .kjh
Step 5: Try to Restore Files Encrypted by .kjh.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and .kjh aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
