Update September 2019. What is Hese virus? This article presents a step-by-step guide on how to remove Hese ransomware virus and how to attempt to recover .hese encrypted files.
Hese virus is a ransomware infection that is based on the code of the infamous STOP ransomware. When started on your computer Hese disrupts system security and encodes personal files. Encrypted files could be recognized by the extension .hese appended by the ransomware. At the end of the attack, Hese virus creates a ransom message that urges you to pay a ransom for the .hese files decryption. This message could be found in the _readnme.txt file which is typically placed on the desktop.

Hese Virus (STOP Ransomware) – Update September 2019
As reported by Michael Gillespie, the operators of STOP ransomware have altered its code in newer versions. These changes make the way the researcher decrypted files impossible, starting with .coharos, .gero, and .hese. Apparently, the cybercriminals started to utilize proper asymmetrical encryption, meaning the offline keys will no longer be valid for decryption after this release of the final keys Gillespie extracted.
The researcher is now working towards closing this decrypter, and continuing work on a new decrypter that will work only for the old versions of STOP (up to .carote), but with some caution. The new decrypter will completely replace STOPDecrypter once it’s released, and will work in a different way, the researcher said.
The first version of STOPDecrypter is designed to support specific offline IDs, so it may not be effective for all occasions of the various iterations of the ransomware.
Hese Virus (STOP Ransomware) – More About the Infection
Security researchers reported that the Hese virus is based on the code of one of the most popular ransomware families dubbed [wplinkpreview url=”https://sensorstechforum.com/remove-stop-ransomware/”] STOP. The spread of Hese ransomware is happening with the help of spam emails, email attachments, hacked web pages, and corrupted freeware installers.
Since malspam (emails that deliver malicious code) enables hackers to spread their ransomware on a large scale, they usually rely on it for their distribution campaigns. Attackers usually embed the malicious code in files of well-known types and then attach these files to email messages. The emails usually state that the attached files are:
- Invoices coming from reputable sites, like PayPal, eBay, etc.
- Documents from that appear to be sent from your bank.
- An online order confirmation note.
- Receipt for a purchase.
- Others.
Once activated on your system Hese virus creates a bunch of malicious files and places them in folders like %AppData% and %LocalAppData%. With the help of newly created malicious files the ransomware corrupts essential system settings and becomes able to encrypt target files.
For the encryption of target files Hese virus launches a built-in cipher module that is designed to scan selected folders for predefined types of files. Every time the module detects a target file, it utilizes a sophisticated cipher algorithm to transform its code. Unfortunately, the threat is likely to corrupt all files which store valuable information. Hence, encrypted may be:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
Following encryption files cannot be opened. In addition, they have the extension .hese at the end of their names. In fact, the main goal of this ransomware is to blackmail you into paying a ransom to hackers. That’s why Hese drops a ransom message with instructions on how to complete the ransom payment process.
You should NOT under any circumstances pay any ransom sum to cybercriminals. This action does not guarantee the recovery of your .hese files.
How to Remove Hese Virus
The so-called Hese 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 the complete removal of all malicious files and objects created by Hese ransomware. That’s why it is recommendable that all steps presented in the Hese virus removal guide below are completed. 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.
How to Recover .hese Files
There are several alternative methods that may be efficient for the recovery of .hese files. You could find them listed under Step 5 from our Hese ransomware removal guide. Beware that you should make copies of all encrypted files and save them on a flash drive for example. This additional step will prevent the permanent loss of encrypted .hese files.

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