Ddsg ransomware (virus) - Decryption Steps Included

Ddsg virus Removal Guide

What is Ddsg ransomware?

Ddsg ransomware – a cryptovirus that demands almost a thousand dollars to regain access to encrypted files

Ddsg ransomwareThe threat is focusing on money demands once files get encrypted.

Ddsg virus is a computer infection developed to racketeer money from its victim by encrypting their personal files and demanding a ransom. This cryptovirus is aimed at everyday computer users and is mainly distributed via file-sharing platforms, camouflaged as cracks[1] for expensive software or games.

If your device gets infected with it, all your personal files, such as documents, pictures, videos, music, archives, databases, or any other file format that's stored on your computer or attached storage devices, are encrypted and renamed by appointing the .ddsg extension to their original filenames.

Only system files are not encrypted, but they suffer from many modifications that the ransomware virus does to establish persistence and become harder to remove. Once the file lockage is completed, a ransom note (_readme.txt) will appear on the desktop. It holds the cybercriminals' demands and instructions and reads:


Don't worry, you can return all your files!
All your files like pictures, databases, documents and other important are encrypted with strongest encryption and unique key.
The only method of recovering files is to purchase decrypt tool and unique key for you.
This software will decrypt all your encrypted files.

We've been in the business of letting people know how to deal with various infections for two decades. So we've observed various tricks used to intimidate the victims and push them into paying the ransom, which in this case is $980. With this ransom note, threat actors are trying to push their victims into making rash decisions.

That's done by offering a 50% discount on the ransom amount if the victims establish contact with their assailants via emails ( or within 72 hours of the attacks. That would lower the price of the decryption tool to $490, but there's no guarantee that it will work or that it will be sent in the first place.

.ddsg file virusData encryption is the process that scares people into paying the ransom.

In addition, you would condemn other innocent people to be attacked as the forwarded amount would motivate Djvu ransomware family distributors, which Ddsg file virus belongs to, to create more malware and attack more computers. Thus we suggest removing the cryptovirus instead.

Besides, you can recover Ddsg files with alternative software. Of course, there's no guarantee that it will work, but it's still a better option than enriching the people who attacked you. All plausible data recovery options are either detailed in this article or in our instructions section.

We're very delighted you chose us to accompany you through this difficult journey, and we'll try not to disappoint you. This article contains illustrated instructions for three vital steps – removal, repair, and recovery. Please don't skip any steps, and you could have your files back by the end of the day.

Road to recover .ddsg files. Step 1 – virus removal

Whether you kept backups of all essential files or not, you can't begin Ddsg file recovery until you've removed the ransomware. Since it's not an ordinary computer infection, manual removal is out of the question because it would be practically impossible to locate all infection components scattered throughout the computer.

You can remove Ddsg virus only by using professional anti-malware software. You have to entrust the process to Malwarebytes or similar well-known and established security tools that are capable of removing any cyber threat and protecting your device from such perils in the future.

Thus click on the link above, download, and install the recommended app or the one of your choice. Then update its virus definitions with the latest malware signatures and perform a full system scan. When it's finished, trust the recommendations of the professional tool on which files or entries should be removed. Only then proceed to the next step.

Virus detection rate for DdsgDjvu family viruses can be terminated via AV tools.

Users have reported that Iqll virus and other Djvu family ransomware blocked them from opening security-related sites. Therefore, they couldn't download any anti-malware software. That's done by editing the host file and making other modifications to the system files and settings.

If that happens when you try to download any security software, you'll have to do that and remove Ddsg file virus after accessing the Safe Mode with Networking feature. We know that not all our readers are highly experienced IT professionals, so here's how to do that on a computer running Windows 10/8:

  1. Right-click on the Start button and select Settings.
  2. Scroll down to pick Update & Security.
  3. On the left side of the window, pick Recovery.
  4. Now scroll down to find the Advanced Startup section.
  5. Click Restart now.Recovery
  6. Select Troubleshoot.
  7. Go to Advanced options.
  8. Select Startup Settings.Startup settings
  9. Click Restart.
  10. Press 5 or click 5) Enable Safe Mode with Networking.

When your infected Windows computer is restarted in the Safe Mode with Networking, you can easily download any anti-malware software that you desire. But since we're in the security business for over 20 years, you can trust that we know good security software when we see one.

Either the abovementioned one or the SpyHunter 5Combo Cleaner are time-tested and proved useful numerous times. Please note that both of these apps come free, but to gain access to additional features, you'd have to buy a license. But rest assured that investing a couple of dollars into cybersecurity could save you hundreds or more on recovery costs.

If you want to keep your device safe from Ddsg ransomware and similar computer infections, you should take precautionary measures. One of which is not to use file-sharing platforms. Other being attentive to what's installed on your device and lastly running full system scans a few times per week.

Step 2 – repairing damaged system sectors

Once you remove Ddsg file virus, it's time to repair corrupted system files and settings. But, once again, you won't be able to do that manually, as each ransomware variation modifies different sections. And by editing the wrong registry entry or other core system file, you could condemn the PC to total failure.

Alterations made by the article's culprit might cause various system failures, such as BSoDs,[2] overheating, severe lag, the previously mentioned inability to use security software, or visiting security-related pages (including, and so on. In rare cases, unfixed modifications might even result in ransomware infection renewal.

Therefore, after Ddsg virus removal, the next step is to repair the virus damage. There are tons of various system optimizers on the market. But other cybersecurity experts[3] from Europe and we highly recommend using the time-proven FortectIntego system diagnostics tool for this task.

Its patented technology finds all system irregularities, like broken DLLs, corrupted files, modified registry entries, etc., and fixes them automatically so that your computer runs as nothing ever happened to it. If you'd like to try it out, here's what you need to do:

  • 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 processReimage installation
  • 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.Reimage results

By employing FortectIntego, you would not have to worry about future computer issues, as most of them could be fixed quickly by performing a full system scan at any time. Most importantly, you could avoid the tedious process of Windows reinstallation in case things go very wrong due to one reason or another. Only after thoroughly cleaning your device can you proceed to data recovery as there's no chance that the infection would renew.

Step 3 – data recovery

When you've completed both prior steps, i.e., performed Ddsg virus removal and repaired damaged Windows directories and settings, it's time to try the best option for data recovery (if you've kept backups, now it's safe to restore your data from them). It's the free decryption software developed by Emsisoft. A company that dedicates its time and money to helping Djvu ransomware victims get their files back without the intervention of cybercriminals.

Unfortunately, this software won't be able to help everyone. It only works if your files were locked with an offline ID due to malware failing to communicate with its remote servers. Nonetheless, it's the best option, and here's what you need to do to try it out:

  • Download the app from the official Emsisoft website.Ddsg ransomware
  • After pressing the 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.
    Ddsg ransomware

When the program is finished analyzing and decrypting files, there are three viable outcomes. If the “Decrypted” message shows up, congratulations, the free decryptor was able to unlock your files, and now you can use them again. When “Error: Unable to decrypt file with ID:” is shown, you will have to be patient, as no one has yet delivered malware samples to the company, so they haven't broken its encryption algorithms.

If the “This ID appears to be an online ID, decryption is impossible” notification pops up, you will have to look for other software or methods to recover Ddsg files. Luckily, we've analyzed them for years and present plausible options below the article in the instructions section.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
