ransomware (Free Guide) - Decryption Steps Included virus Removal Guide

What is ransomware? ransomware is the virus that uses the RSA encryption algorithm and demands the victim to contact criminals via the email ransomware is the Djvu virus version that uses the particular email and appears to be more active than other variants in the same family. ransomware is the threat that encodes common files to have a reason for the ransom demand delivered in the _readme.txt immediately after the encryption process. The note from cryptovirus developers includes a typical text used by DJVU ransomware versions for years now and a particular victims' ID, contact information. The email is the feature that many victims indicate online mostly. It is believed that these last two versions, including the same email in their contact information section, are more active than other ones released recently.

If you find that your machine got affected by the ransomware virus, it resembles Zobm ransomware and Rote virus infections and indicates that your computer needs some serious malware cleaning if you want to get your files back. Unfortunately, solutions don't include decryption for a while because the last two tools capable of file recovery cannot help with versions released after August 25th. First Djvu virus variants were decryptable with the help of STOPDecrypter after that, Emsisoft released a tool that can decrypt files affected by the 148 versions and some other files encoded using offline keys. However, for others, the best solution remains anti-malware tools and data backups.

The main vectors for delivering the ransomware payload used by this family are infected files[1]
Elimination There is no debate whether you need ransomware removal or not, but the best solution for the infection is the anti-malware program that can detect and eliminate this virus fully
System recovery Encryption affects common types of data, but system folders, directories, and other system preferences get corrupted without your notice. To tackle that virus damage, you should run FortectIntego or another system tool on the machine, so files get repaired without the risk ransomware is the malware that focuses on blackmailing victims because developers are focused on gaining money from users. The attack starts with choosing files for encryption, then the particular algorithm is employed for encoding – the original code of the image, video, audio file or document gets altered and makes the data unopenable.[2]

Encryption is possible due to particular keys that get used by the virus. However, the more recent versions in the same family, including ransomware, started to rely on more difficult and unique methods when the connection to the C&C server is included when IDs get generated. This is why decryption is no longer possible for variants released after August of 2019 when these major changes got made.

The file that contains all the contact information and the particular victims' ID is named _readme.txt and gets delivered on the desktop immediately after file-locking. The message remains the same for all the versions and offers the discount as an options for victims. You shouldn't believe a word in the following note:

Reserve e-mail address to contact us: ransomware ransomware is the cryptovirus developed recently but most of the features remain unchanged for three years or more. The ransom note placed in the _readme.txt file is one of them. Since decryption is not an option, you should remove ransomware and focus on file recovery after that. Keeping the threat on your machine gives nothing and can give more time for the additional scripts to get loaded. In some cases, AZORult trojan gets released on the already infected machine to collect data and personal or sensitive details from the computer.

You may store encrypted files on external devices with the hope that the decryption tool for the virus will get released later on. However, many researchers speculate that ransomware remains persistent until law enforcements get to catch hackers behind it or their databases get leaked, encryption process changes again.

Experts[3] note that you need to go straight to ransomware removal after receiving the ransom message because the biggest damage is done, and there are only a few minutes when you still avoid further infections and permanent corruption to the system.

When you get rid of the malware using the proper anti-malware application, you can then focus on recovering files encrypted by the ransomware. That might be difficult or barely possible because of the encryption methods and malware persistent.

Additionally, ransomware runs other processes in the background and alters parts of the system to keep the machine infected for longer. Shadow Volume Copies get deleted, security functions disabled and Windows Registry entries deleted or changed. When the inexperienced user tries to fix these issues manually permanent damage can be done, so rely on FortectIntego or a different PC repair tool and try to fix the damage this way. is the email used by the more recent versions in Djvu family appending encoded files using .zomb and .rote extensions.

Cracked software and game cheats lead to legal and PC security issues

The most common technique used by malware providers and developers is relying on gullible people and deceptive methods. Hacked website, copies of legitimate services, and provider domains spread fileless malware, trojans, cryptocurrency miners, and even the notorious ransomware.

Each team of criminals, virus family has different methods, and go-to techniques, so do this one. Pirated software, video game cheatcodes, software cracks, and other content that can be downloaded from torrent services, networks, and illegal sites come pre-packed with malicious files.

Spam emails often do too, so paying attention to such details can cost you important files or even money. When an infected file ends up on the machine, you as a user only need to trigger the malicious script execution that happens with a few clicks of the mouse: when you install the crack or download the file filled with macros. Keep anti-malware tools that can check such downloads beforehand. ransomware elimination and file recovery options

Since ransomware virus is one of 187 variants in the notorious cryptovirus family, you should react as soon as possible and don't even consider paying a penny for those criminals. Fulfilling their wishes gives nothing for you in the long run because the alleged decryption key most likely is not going to reach your device.

As for ransomware removal, you need to employ professional anti-malware tool and try to eliminate any malware-related files or applications to ensure that data can be recovered on the safe system. This is best achieved with tools like SpyHunter 5Combo Cleaner, or Malwarebytes that keep the machine protected from various intruders.

As for your encrypted files and particular damage that the virus left behind, you need to remove ransomware itself completely and then try to get the system back to a normal state using a system application like FortectIntego that may find and fix corrupted system files for you. File recovery after encryption takes a bit more effort, some options are listed below.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by, you can use several methods to restore them:

Data Recovery Pro is the program that can help with ransomware affected files

People encounter various incidents when their data requires repairing, so Data Recovery Pro can restore encrypted or accidentally deleted files

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by ransomware;
  • Restore them.

Windows Previous Versions recovers data affected by the ransomware

When you fight ransomware using System Restore, you can recover locked data using Windows Previous Versions feature

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Try ShadowExplorer for data recovery

Unfortunately, this method can work for a system infected by ransomware when the virus is not affecting Shadow Volume Copies that are needed for the restoring process

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored. ransomware belongs to Djvu family, so it might be possible to decrypt some files with DJVU decryptor

Emsisoft Decryptor for STOP/Djvu virus can be helpful for files encrypted using offline keys

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from and other ransomwares, use a reputable anti-spyware, such as FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
