Jdyi ransomware is file-locking malware that barely changes from its previous versions
Jdyi 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 an RSA encryption algorithm,[1], which also appends a .jdyi extension in the process. Victims are required to pay up for the unique decryption key, which is in possession of cybercriminals behind the ransomware. This is the 261 on the list of Djvu ransomware versions, so paying is not the recommended option. You should stay away from this threat and try to eliminate it as soon as possible.
Once the encryption is complete, it drops a ransom note _readme.txt . This file placed in various folders, contains instructions from cybercriminals. The note explains to victims what happened 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 (helpmanager@mail.ch, restoremanager@airmail.cc).
You shouldn't even consider contacting them because all those claims are not true, in most cases, victims cannot get their files restored without proper backups or official decryption tools. However, at this point, Djvu/STOP ransomware family is not decryptable since the online IDs, and powerful encoding techniques got employed back in august of 2019.

| Distribution | Malicious files get distributed around via spam email attachments, pirated software can also include payload of such ransomware |
| File recovery | If no proper file backups are available, recovering data is almost impossible. You can try to restore media files with a particular tool or rely on Emsisoft's decryption method. Other alternate methods listed below |
| Malware removal | Perform a full system scan with powerful security software |
| System fix | Malware can seriously tamper with Windows systems. Changes in system folders and functions create errors and corruption of proper work. To remediate the OS, try scanning it with the FortectIntego tool |
This malware encrypts all the important files on a Windows computer and restricts access to them. In the ransom note, cybercriminals explain that the only way to recover data is by paying ransom in Bitcoin. The amount the attackers' demand and the initial ransom message, text file hasn't got changed or altered in any way for a while.
Criminals try to create legitimacy or fake the trust between them and the victim, so a 50% discount is offered in the first 72hours. However, if you think that paying $490 is less dangerous than transferring $980 in Bitcoin, you should think twice. There are fewer than a few chances to get the decryption tool. In more cases, victims receive additional malware or get extorted for bigger sums.
The ransom note delivers the following message:
ATTENTION!
Don’t worry, you can return all your files!
All your files like photos, 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.
What guarantees you have?
You can send one of your encrypted file from your PC and we decrypt it for free.
But we can decrypt only 1 file for free. File must not contain valuable information.

The locked files require a unique decryption key to unlock them, experts[2] recommend not paying the ransom since payment transfers often result in financial losses. The best way to restore affected files is to recover them using proper copies from data backups or external drives.
Note that this can only help when the threat is removed already. So rely on SpyHunterCombo Cleaner or MalwarebytesMalwarebytes tools, anti-malware programs that can find the threat, and properly remove Jdyi ransomware from the machine without causing additional issues with the security or performance. Manual virus termination is neither easy nor possible because you cannot find all the files associated with this infection yourself.
Once inside, malware locks up all documents, archives, videos, music, and other files, but it can directly affect system files. Then ransomware can control what programs to disable, which files to delete or corrupt. These alterations affect the persistence of the cryptovirus and interfere with termination. For such instances, you need tools like FortectIntego that can indicate, check, or even fix such file corruption issues for you.
This virus derives from a well-known family, which was first spotted in 2016 at least. Since then criminals behind the malware released multiple variants, including .efji, .iiss, .mmpa. This variant is pretty much identical to any version released this year, since the group spreads new variant each week.
Possible ways to recover after the virus attack
Ransomware removal is the procedure that is most important in an instance like this. You cannot recover files or place backups, use decryption tools on the machine that is still infected with the ransomware. You might suffer permanent loss of money if you pay or get data corrupted/ encrypted again when the virus is still active.
Online IDs are used for each victim who gets a unique identification key that is needed for the file recovery later on. However, it is less likely to receive a decryption tool from criminals, even if you pay the ransom. Criminals are not worthy of your trust. Waiting for the official decryption tool is not an option either because it takes a long time to develop such an application.
You need to get rid of the virus first. Then you must restore functions and system files that possibly get altered or corrupted by the the virus itself. When you double-check with anti-malware tools and can be sure that the system is virus-free, you can move on further and rely on your data backups, files from the cloud, or external storage and replace affected pieces.
Ransomware is dangerous: do not get infected in the first place
Djvu virus is extremely prevalent: according to Emsisoft security researchers, this strain accounts for more than 70% of all ransomware infections that were submitted by the infected users.[3] This statistic is extremely alarming, as it means that malware is extremely successful in infecting victims worldwide.
So, how did criminals manage to reach sight success, while others did not? Of course, it comes down to the successful distribution methods that the attackers are using – malicious installers placed all over the web. However, users are not aware that they are downloading malware, as the payload is disguised as a program crack, loader, or a similar tool. These are typically used to bypass the licensing process of well-known applications, such as, for example, Photoshop.
Since some of the apps can be pricey, many choose to download pirated versions instead and get them for free. Without a doubt, users who have their security apps installed would be information about the imminent danger. However, since software cracks are most commonly flagged by security solutions, users choose to ignore these warnings and sill open the malicious file.
Therefore, it is vital that you stay away from insecure third-party sites that host illegal software installers and cracks, as it is one of the first methods to get your computer infected with file-encrypting malware. As soon as you execute the file, Jdyi virus files will be out of reach, possibly forever. Besides, keep in mind that previous versions of malware were commonly distributed with other infections, such as AZORult banking Trojan.
Delete the ransomware infection before attempting to recover .Jdyi files
Since this virus can spread around from pirated software pages, during the download of illegal software activators, and so on, you might have more intruders on the machine than this malware alone. This is why we recommend getting anti-malware tools and running the program fully.
When you rely on anti-malware tools like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes and remove Jdyi ransomware, you can see the list of detection names that include this threat and other possibly related programs or infections. There are trojans that this threat can be used to spread with or additional malware that ends up added after encryption.[4]
Ransomware removal is not the same as file recovery, so rely on proper tools that can restore affected pieces for you or system features that offer to restore data after such infections. As for PC repair and system recovery, try applications like FortectIntego, so any alterations and corrupted data, virus damage can get fixed.
