An infection with the Repp ransomware virus leads to serious issues that affect the overall system security. The most unpleasant consequence is the encryption of valuable files. This removal guide shows illustrated instructions on how to get rid of Repp virus infection.
Repp Ransomware Removal
According to information shared by security researchers, the so-called Repp virus is a ransomware that is based on the code of one of the biggest ransomware families called STOP/Djvu. Numerous strains of this ransomware family have appeared on the malware scene since the original variant was released in the wild.
Like its predecessors, the Repp virus is designed to corrupt essential system settings with the goal to pass through several attack stages. As a consequence, the ransomware leaves all important files encrypted and renamed with the .repp extension. Then it extorts a ransom fee for the decryption of encrypted personal files. The extortion is realized via ransom message. This message can be found in the text file _readme.txt
In the beginning, the ransomware corrupts system settings that will help it to evade detection and hide malicious files. Beware that when an infection with Repp ransomware occurs, some major registry keys like RUN and RUNONCE are contaminated. The reason is that their functionalities can enable it to launch malicious files every time the infected system is started. The end of the attack takes place when a ransom message pop-ups on the screen to extort a ransom fee from victims.

Repp Virus – More About the Infection Process
As you have just understood Repp virus is called to a data locker ransomware that belongs to one of the biggest ransomware families STOP/Djvu. The name of this strain is a derivative of the malicious extension .Repp it appends to files it encrypts. The same goes with the names of its recently discovered pedecesors Npsg virus, Btos virus, Zobm virus and Reha virus.
Techniques like spam emails, email attachments, hacked web pages, and corrupted freeware installers are likely to be utilized for the spread of Repp ransomware virus. Since malspam propagation technique enables hackers to spread their malicious code on a large scale it is considered to be the main one. Malwpam technique (massive email spam campaigns that try to deliver malicious code) has its traits. So how to recognize an email that endangers the overall security of your PC and data stored on its drives? First: Does the email have an attached file of common type or a link presented as a button, an image, a plain URL or another clickable form? If the answer is positive then avoid interacting with these elements. If you believe that you should view the content then scan the file / link with online malware scanners like VirusTotal. The results will provide information about the security level of the content.
Among the most popular Windows file types that are used by malware are executable files, documents and other Microsoft Office files, application files, script files, PDFs, temporary files and other.
.repp File Extension
All initial malicious changes performed by the ransomware enable it to reach the encryption stage. During this stage, the ransomware launches a built-in cipher module to corrupt personal files. Specific folders are scanned for commonly used types of files as they are likely to store valuable user data. Every time a target file is detected, its code is transformed via a strong cipher algorithm. As a result of encryption, corrupted files receive the malicious extension .repp
Unfortunately, encrypted files remain inaccessible after encryption. The malicious file extension .Repp may appear at the end of document, music, project, database, image, video, backup, archive, and audio files.
In fact, the end goal of Repp ransomware is to blackmail its victims into paying a ransom fee to hackers who stand behind the attacks. A ransom note file called _readme.txt informs that the decryption of corrupted files can be realized after a payment of $490 – $980 ransom fee. The full content of this file can be seen below:

How to Remove Repp Ransomware Virus
The so-called Repp ransomware virus is a threat with a highly complex code that disrupts system security in order to encrypt personal files. Hence the infected system could be used in a secure manner again only after you remove all malicious files and objects created by the ransomware. The steps presented in the ransomware removal guide below will help you with the complete removal process. Beware that the manual ransomware removal is suitable for more experienced computer users. If you don’t feel comfortable with the manual steps navigate to the automatic part of the guide. It is also worth mentioning that personal data remains encrypted even after the complete removal of Repp ransomware. Its removal only prevents it from causing further encryptions and security issues.
Step 5 from our Repp ransomware removal guide presents alternative data recovery methods that may be efficient for the recovery of encrypted files. Beware that you should make copies of all encrypted files and save them on a flash drive for example before the beginning of the recovery process.

Step 2: Uninstall Repp 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 Repp 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 Repp 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 Repp
Step 5: Try to Restore Files Encrypted by Repp.
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 Repp 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.

Hello Achille,
If you are unsure whether or not a certain registry value is related to the virus we recommend that you don’t edit and/or delete it. You can certainly try and see if this resolves any issues however we do recommend that you backup your system before doing so.
