How to remove Dehd file virus

Dehd ransomware is a virus designed to lock files on your computer and hold them hostage until a ransom is paid

Dehd ransomware is a malicious program designed to encrypt all personal data on the computer and then demand ransom for its return. Once inside the system, it encrypts all personal pictures, videos, documents, archives, and other files by using a strong encryption algorithm, which also appends a .dehd extension in the process. Victims can no longer access these files, and require a unique key that is in possession of cybercriminals behind the ransomware.

Once the encryption is complete, Dehd virus drops a ransom note _readme.txt – instructions from cybercriminals. It explains to victims what happened to their files and claims that the only method to return them is by paying a ransom for a decryption tool. For negotiation purposes, crooks also provide emails manager@mailtemp.ch, helprestoremanager@airmail.cc.

Dehd ransomware is a cryptovirus that belongs to a malware family known as Djvu ransomware. This malware encrypts all the important files on a Windows computer and restricts access to them. On the ransom note, that is not changed for years, cybercriminals explain that the only way to recover data is by paying ransom in Bitcoin. The sum of $980 is not altered for a while too. As well as the discount offer of 50%. This feature should encourage people to pay, but do not fall for this.

While it is true that Dehd virus files require a unique decryption key to unlock them, experts^[1] recommend not paying the ransom, as cybercriminals might not keep their promises, resulting in financial losses.^[2] In this article, we will explain how to get rid of malware and use alternative methods for data recovery.

More on file-locking malware

Dehd ransomware is a virus that attacks Windows computers by using various infiltration methods available. The infection focuses on wide distribution all over the world. Once inside, it uses an encryption algorithm to lock up all documents, archives, videos, music, and other files. System data is not encrypted but damaged directly. These changes can ensure persistence.

According to Dehd virus authors, victims need to contact them via email and provide their personal ID. Once that is done, users should receive further instructions to proceed with the payment, provided in bitcoin cryptocurrency. Nonetheless, we do not recommend contacting the attackers because they might not deliver the required decryption tool. Check out the alternative methods we provide below instead. The official decryption tool is not developed yet, but some of the options can be useful for victims of this threat.

The _readme.txt reads the following:

Your personal ID:

This virus derives from a well-known family which was first spotted in 2018 and since then released multiple variants, including miia, xcmb, sbpg. Versions are minimally changed and have the same ransom note, contact emails listed there. these developers demand the same amount since 2019, but the encryption methods got advanced. Meaning that decryption is barely possible.

Removing the Dehd virus

It is always important to be cautious when dealing with malware. Even if you paid the hackers, there is no guarantee of getting what was promised in return. Malware developers can release another infection instead of providing the proper decryption tool. You need to get rid of the virus as soon as possible. The best way to do so is by relying on detection^[3] and employing an anti-malware tool.

The best advice we could give anyone caught up in this situation: don't pay them anything at all unless absolutely necessary because chances aren't good enough anyway. Companies and large targets stay away from paying, especially when it comes to large families of threats like this one.

And secondly, make sure your antivirus program covers everything because sometimes newer versions have bugs. Try relying on updated anti-malware applications like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes, if you do not have the tool of your choice. The full system scan helps to find out if Dehd virus or other related infections are currently present in the computer before using any programs that could put sensitive information at risk of being stumbled upon by potentially unwanted visitors.

The infection can alter the Windows registry database, damage vital bootup, and other sections, delete or corrupt DLL files, etc. Once a system file is damaged by malware, antivirus software is not capable of doing anything about it, leaving it just the way it is. Consequently, users might experience performance, stability, and usability issues, to the point where a full Windows reinstallation is required.

Therefore, we highly recommend using a one-of-a-kind, patented technology of FortectIntego repair. Not only can it fix virus damage after the infection, but it is also capable of removing malware that has already broken into the system thanks to several engines used by the program. Besides, the application is also capable of fixing various Windows-related issues that are not caused by malware infections, for example, Blue Screen errors, freezes, registry errors, damaged DLLs, etc.

• Download the application by clicking on the link above
• Click on the ReimageRepair.exe
  
  
• If User Account Control (UAC) shows up, select Yes
• Press Install and wait till the program finishes the installation process
• The analysis of your machine will begin immediately
• Once complete, check the results – they will be listed in the Summary
• You can now click on each of the issues and fix them manually
• If you see many problems that you find difficult to fix, we recommend you purchase the license and fix them automatically.

Decryption options for some of the versions in the family

It is possible for trojans and other malware to act as vectors in the distribution of cryptoviruses. The infection can spread further than you think, so double-checking before doing anything else will be very important when trying to repair your files affected by this ransomware virus. Focus on the virus removal first, then worry about those encoded files.

The ransomware is connecting to various remote servers, and criminals can control the activities this way. When Dehd ransomware cannot properly connect while encrypting your files it uses a built-in encryption key that is unique for every version of the program, but not the user. meaning that decryption is more obtainable when offline keys are used instead of online IDs.

When offline IDs get used, all can use one code for decrypting the locked information and it is possible with expert help because only an expert has access to reverse engineering these threats. Online keys are needed when the ransomware is more advanced, so decryption these days is not possible since the Dehd ransomware has been further improved.

Nevertheless, you still should try using the available options. If your computer got infected with one of the Djvu variants, you should try using Emsisoft decryptor for Djvu/STOP. It is important to mention that this tool will not work for everyone – it only works if data was locked with an offline ID due to malware failing to communicate with its remote servers.

Even if your case meets this condition, somebody from the victims has to pay criminals, retrieve an offline key, and then share it with security researchers at Emsisoft. As a result, you might not be able to restore the encrypted files immediately. Thus, if the decryptor says your data was locked with an offline ID but cannot be recovered currently, you should try later. You also need to upload a set of files – one encrypted and a healthy one to the company's servers before you proceed.

• Download the app from the official Emsisoft website.
• After pressing Download button, a small pop-up at the bottom, titled decrypt_STOPDjvu.exe should show up – click it.
  
• If User Account Control (UAC) message shows up, press Yes.
• Agree to License Terms by pressing Yes.
  
  
• After Disclaimer shows up, press OK.
• The tool should automatically populate the affected folders, although you can also do it by pressing Add folder at the bottom.
  
• Press Decrypt.
  
  

From here, there are three available outcomes:

1. “Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
2. “Error: Unable to decrypt file with ID:” means that the keys for this version of the virus have not yet been retrieved, so you should try later.
3. “This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.

Getting the Dehd file virus on your computer is not something you should ignore. The sooner it is taken care of, the better because major system issues can be avoided that way and fixed before they become an issue later down the line. If you run into issues with your computer, like slow responsiveness or errors popping up when using certain programs then it may be due to a virus and its malicious files.

To get rid of the virus as soon as possible and make sure that nothing else gets left behind on the system use the AV tool like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes. We also recommend using FortectIntego for the system performance improvements, since these repair tools work to restore additionally caused problems such as bad performance speed.
