Dehd Virus


Dehd is a dangerous malware program that encrypts sensitive user data and forces the victim to pay ransom for its release. If the user refuses to pay the Dehd ransom, the locked files are to remain inaccessible for good.

If your computer has been struck by this malicious threat, you should have access to some basic information regarding this type of harmful viruses. Otherwise, you may do something out of impulse without first rationally assessing the situation, which could, in turn, lead to more issues.

The first thing you must realize is the fact that this Ransomware won’t harm your computer. It will simply lock the files that are on it and try to get you to pay for their release by showing you a blackmailing note. However, if none of the sealed files are that important to you, the situation isn’t all that serious. Ransomware viruses can be removed if you know what to do or if you have access to a reliable removal tool. In our guide on this page, you will find detailed removal instructions and a helpful anti-malware tool that will help you with the elimination of the threat. Make sure to remove the virus ASAP so that no more files get encrypted on your computer!

The Dehd virus

The Dehd virus is a malware threat that belongs to the Ransomware virus category – a type of hazardous viruses known for their blackmailing abilities. The Dehd virus enters your system silently and launches a secret data-encrypting process that makes all affected data unavailable.

Once the encryption is applied to the user’s files, the targeted data becomes totally inaccessible and no regular program that one may have on their computer would be able to open the encrypted files. As we pointed out earlier, if the files this Ransomware has managed to lock on your computer aren’t too important to you, then you can simply remove the virus with the help of our guide and forget about this problem. However, what if the files that have gotten locked are important to you? Should you then pay the ransom required by the hackers for the data’s release? While there is no universal answer to this question, the usual advice given to Ransomware victims is to refrain from paying because they may simply lose their money without regaining access to the sealed data.

The Dehd file extension

The Dehd file extension is a special file extension used by this virus to change the format of the targeted user files. Once the Dehd file extension is added to the name of the user’s files, the latter become unreadable to any conventional software.

If you see the Dehd or Miia file extension at the end of your files’ names, this means you will need a special key to open the files and without this key, the data will remain unavailable. To get this key, the hackers want you to pay a ransom, but we already established that doing this isn’t a good idea. Instead, what we’d advise you to do is follow the removal steps from below and then check out the suggestions in the file-recovery section of our guide – they may help some of you get some of your data back.

Remove Dehd Ransomware


If you’ve been infected with Dehd, the first thing you should do is bookmark this webpage with removal instructions, so you can have quick access to it. Next, the infected machine should best be rebooted in Safe Mode, as explained in this link. Once you’ve done these preparations, you can safely proceed to the instructions below to remove the traces of Dehd from your computer.



The next step is to look for any processes associated with the ransomware in the Processes tab of the Task Manager. You open the Task Manager, press CTRL + SHIFT + ESC keyboard keys together, then select the second tab from the top. Look at how much CPU or memory the processes consume, or look at their names to identify any suspicious-looking ones.

When you isolate a suspicious process and right-click on it, you can select Open File Location, and check its files for malicious code.


To be on the safe side, these files need to be scanned with an antivirus program. Those without access to a reputable anti-virus program can use the free online virus scanner provided below:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    If the scan results show that there is a danger, right-click on the process that is associated with the infected files and select End Process. The File Location folder must be cleared of all dangerous files before moving on.


    In the third step, we will explain to you how to look for any alterations to your system’s Hosts file that can indicate a possible hacking. To do that, hold down the Windows key and R at the same time, then copy/paste the line below in the Run window that pops on the screen and press Enter:

    notepad %windir%/system32/Drivers/etc/hosts

    In the text of the file, look for anything strange under Localhost, such as Virus Creator IPs like those on the example image below:

    hosts_opt (1)

    If you come across such IPs under “Localhost,” please leave us a comment below this post. They’ll be checked by a member of our team, who will tell you what to do if anything suspicious is found.

    As long as there are no unauthorized modifications in your Hosts file, you don’t need to do anything. Just close the Hosts file and return to the Windows Search field.

    Type msconfig in the search and press Enter:


    Select “Startup” from the tabs at the top, and be sure to do some online research on any startup items with “unknown” manufacturer or random names that you find in the list. If you find enough information that a specific startup item is dangerous and is connected to Dehd, you can disable it by unchecking its respective box and clicking OK.


    Once it has gained access to the system, a ransomware like Dehd has the potential to add malicious entries to the registry. What is more, it is possible that the malware could resurface if these registry entries aren’t removed. Therefore, you’ll need to go through your registry and carefully search it in order to completely remove Dehd.

    Attention! There is a risk of system corruption when important registry files and apps are modified or deleted. For this reason, ransomware victims are advised to remove potentially hazardous files from critical system locations like the registry only with the help of specialized malware removal tools.

    If you want to proceed with the manual removal of Dehd anyway, please open the Registry Editor and check for Dehd-related entries that need to be removed.

    To do that, type regedit in the Windows search field and hit Enter. When the Registry Editor starts, press CTRL and F from the keyboard to access the Editor’s Find window. In it, type the ransomware’s name and start a search. If there are files with that name in the search results, they need to be carefully deleted. 

    Using the Windows Search field, run a new manual search for Dehd-related files in each of the five locations listed below: 

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

     If there are no suspicious files or subfolders, you should not make any changes. However, if there are, you should get rid of them. To remove the ransomware’s temporary files, just delete everything in the Temp directory.


    How to Decrypt Dehd files

    If a ransomware encrypts your files, you’ll have to figure out a way to decrypt them if you want those files back. To minimize the damage caused by the Dehd attack, we recommend you start with reading this file decryption guide to learn the most up-to-date file-recovery options.

    Before applying any of the file recovery steps described in the guide, however, please make sure that your system is free of Dehd. To do that, you can run a thorough system scan using the free online virus scanner or the anti-virus software suggested on this website, you can comment below if you need assistance with any of the steps in this Dehd removal guide. or the anti-virus software suggested on this website, you can comment below if you need assistance with any of the steps in this Dehd removal guide.
