Jhdd

Jhdd is a dangerous file-attacking piece of malware aimed at blocking your data until you send a ransom payment to its creators. Threats like Jhdd belong to a widespread category known as Ransomware and their main job is to blackmail users.

The Jhdd virus file ransom note

The main issue with Ransomware cryptovirus infections like Jhdd, DmayMsjd and Ygvb isn’t their removal, it is the recovery of the files that they have locked-up. In fact, removing a Ransomware cryptovirus isn’t all that difficult – there are many security programs that can handle this, and you can even do it manually yourself (we will show you how in the guide below). The real problem with a cryptovirus attack is the fact that once the files that the virus has targeted become locked by its data-encryption, there are pretty much no way to guarantee their recovery. Of course, the hackers behind Jhdd and other similar infections readily offer their “assistance” with the restoration of the sealed files but only if their victims are willing to pay them a certain amount of money first. The problems with this option, however, are more often than not a deal-breaker. First and foremost, there’s really no way to trust those people – their promises of sending you a decryption key mean nothing, because as soon as the ransom money they demand of you is in their possession, there is nothing anyone can do to make them send the promised key.

The Jhdd virus

The Jhdd virus is an advanced cyber threat that targets important user data with the goal to block access to it. If the user attacked by the Jhdd virus doesn’t complete a ransom payment, the hackers threaten that access to the files will never be restored.

Another problem wit the ransom payment is that not all users can afford to pay the requested amount of money to begin with – usually the demanded sum is several hundred dollars, but in many cases it may even be in the thousands. And last but not least, paying the criminals would more than likely encourage them to keep on doing the same thing – blackmailing more and more users on the Internet for the access to their files. However, if the Ransomware hackers see that regardless of their harassment schemes, the users aren’t giving in to their demands, they may reconsider this tactic. Of course, there isn’t really a conceivable way in which this could happen – cryptoviruses like Jhdd oftentimes attack the networks of big businesses and institutions and lock some highly important data – in such cases, the payment is pretty much the only way to quickly retrieve the data (even if there is no guarantee that the files would actually get restored). Of course, a backup of all the important data which a Ransomware may lock changes everything, which is why we always try to remind our readers of just how effective of a precaution against Ransomware such file backups can be.

The Jhdd file extension

The Jhdd file extension is a short string of characters that is placed at the end of the filenames of all files encrypted by the virus. The Jhdd file extension cannot be removed through conventional means and will keep your files unrecognizable to any program.

We already told you that we will show you how to remove this infection – simply make sure to follow the steps from the guide. As far as the file recovery is concerned, you can try some of the recommended alternative options that we have on our site. Sadly, we cannot promise that those options would work in all cases – the encryption used by this sort of malware is very advanced and dealing with it may not always be possible at the given moment. Still, if you want to at least avoid putting your money on the line, this is the advisable course of action – remove Jhdd and then try the alternatives.

Remove Jhdd Ransomware


Step1

For starters, please save this page’s removal instructions as a bookmark in your browser so that you don’t have to look for them each time your computer restarts. This will save you time in the long run.

Rebooting the system in Safe Mode is the next step if your computer has been infected, since it allows you to see what applications and processes are currently operating in the background. Restart your computer and then go to step two by clicking on the bookmark you saved earlier.

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

The second step is to launch the Task Manager (by pressing CTRL+SHIFT+ESC at the same time) and check the Processes tab for processes with unusual names or processes that use a significant amount of resources. To see the files associated with a suspicious process, right-click on it and then choose Open File Location from the pop-up menu that appears on the screen.

The next step is to look for any harmful code in the files associated with that process. To make things quicker and more convenient, we’ve provided a direct link to a free malware scanning tool.

    Before removing the files that the scanner has identified as potentially malicious, you may need to stop the suspicious process in Task Manager by right-clicking on it and selecting End Process.

    When a computer is infected, an attacker may make changes to the Hosts file. As a result, the next step is to manually examine the “Localhost” section of the file for IP addresses that may be troublesome (like those on the image below). You may access your computer’s Hosts file by pressing both Windows and R keyboard keys at the same time and then pasting the command below in the Run box:

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

    After pressing Enter, check the Localhost section of the file for any unusual IP addresses. Any questionable IPs should be reported in the comments section provided below. If any of the IP addresses you’ve shared with us turn out to be dangerous, we’ll give you some advice in the comments.

    Next, type msconfig in the Windows Search bar and press Enter. You will see a window titled System Configuration. The startup tab contains a list of items that are set to automatically start when you start the computer. Carefully look at the list and remove the checkmarks of those items you consider to be ransomware-related. Don’t remove the checkmark from startup items that are part of your legitimate apps or the computer’s OS.

    A growing number of malware programs are attempting to avoid detection and stay operational for a long period of time by inserting malicious registry entries in the system. It’s thus essential that you go into the Registry Editor and remove any Jhdd-related files that may have been added there without your knowledge. You may access the Registry Editor by typing regedit in the Windows search bar and pressing Enter.

    Next, you may search for files that may be linked to the ransomware by pressing CTRL and F in the Registry Editor window. If you do this, a Find box will appear where you may input the threat’s name. Click the Find Next button to begin searching for ransomware-related entries inside the registry. Delete any files that appear in the search results.

    Attention! To avoid accidentally deleting legitimate files when manually removing malware-related registry entries, security experts recommend using an anti-virus tool since it removes potentially harmful applications and registry entries while leaving the rest of your system intact.

    The following five locations on your computer may also be infected with ransomware-related files. This is why you should type each of the search phrases listed below in the Windows search bar and then press Enter to open them.

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

    Don’t make any modifications or deletions if you aren’t sure about the files that you find in these locations. Holding down the CTRL and A keys on your keyboard and pressing the Del key will remove all temporary files from your computer’s Temp directory.

    Step5

    How to Decrypt Jhdd files

    Non-experts may have difficulty decrypting ransomware-encrypted data because recovering encrypted data is made more challenging since the decryption methods that may be employed depend on the variant of ransomware that was used to encrypt it. The ransomware variants may be distinguished by the file extensions that have been attached to the end of the encrypted files.

    However, it’s NOT safe to look into the file recovery options that are available before you make sure that the ransomware has been completely removed from the infected system. The best way to check that is to run a full scan of the system with a reliable security program (like the one offered on our website), or another trusted anti-virus tool of your choice Once the malware has been removed from your computer, and there are no other signs of its presence, you may begin the process of data recovery.

    Next Djvu Ransomware

    It has been reported that security experts have uncovered a new form of Djvu ransomware called STOP Djvu. In case of attack with this threat, the suffix .Jhdd is typically applied to the filenames of the newly encrypted files. With a decryptor like the one offered at  https://www.emsisoft.com/ransomware-decryption-tools/stop-djvu, however, you may have a chance to recover some of your data without paying to the crooks.

    Before you can begin decrypting the data,  though, you must first download the STOPDjvu.exe application to your computer. Select “Run as Administrator” from the context menu of the downloaded file, and then click Yes to proceed. Make sure you read the license agreement and any accompanying instructions before using it. Keep in mind, however, that this application cannot decrypt data encrypted using unknown offline keys or with online encryption.

    If you’re having trouble eradicating the Jhdd ransomware, try using the anti-virus software on our website or use our free online virus scanner to scan suspicious files.
