.Jdyi
.Jdyi is among the most advanced threats identified by security researchers as ransomware. Threats like .Jdyi are particularly harmful and hard to detect inside the computer until they secretly encrypt your files and display a ransom-demanding message on your screen.

The Jdyi virus will leave a _readme.txt file with instructions
Nowadays, it is not uncommon for most of us to keep all sorts of personal or work-related data files saved on the hard drive of our computers. Essential system and software records, business or study-related files, projects, audio or video recordings, personal photos, and more are just some of the valuable pieces of data that could become a target of a file-encrypting virus like .Jdyi . Most web users, however, do not have a backup of their important data and this is precisely what the ransomware virus authors are relying on.
Ransomware is a very stealthy and very problematic type of malware, used by online hackers for blackmail and money extortion purposes. In general, there are two major subcategories of ransomware which may attack your computer – screen-lockers and cryptoviruses that are specialized in data encryption.
The screen-locking ransomware representatives can cause problems by restricting the access to your computer’s screen by placing a huge full-screen banner on it. The role of this banner is to prevent you from reaching out the icons and the menu of the infected device and to force you into paying a ransom in order to get removed. However, in most situations, coping with such a ransomware virus is not very complicated. The same cannot be said of the representatives of the cryptovirus subcategory of which .Jdyi, .Efji, .Mmpa belongs.
The .Jdyi virus
The .Jdyi virus is an advanced ransom-demanding infection that is specialized in file encryption and money extortion. Threats like the .Jdyi virus are the worst, and their victims commonly struggle to recover from the effects of their attack.

The .Jdyi ransomware will encrypt your files
Normally, once the cryptovirus sneaks inside the computer (this could happen through a lot of stealthy methods), it searches the entire system and locates certain file formats (for instance, documents, images , audio, video, archives, databases, etc.), which are considered of great value for you. After doing so, the malware begins an encryption phase where each detected file is encrypted with a complex code that renders it unreadable. This code is typically reversible but it requires a specially generated decryption key that is kept in secret by the hackers who control the ransomware. After all of the data is locked, a malware-generated ransom note warns the victim that if they want to be provided the decryption key, they will have to pay a certain amount of money to the hackers.
The .Jdyi file encryption
The .Jdyi file encryption is not a process that does harm to the computer. In essence, the .Jdyi file encryption is a data-encoding process that will work quietly without any noticeable signs and will affect only certain types of digital data stored on the infected machine.
The ransomware cryptoviruses are some of the sneakiest and stealthiest types of software and that makes them tougher to manage. .Jdyi, in particular is a recent representative which has already managed to compromise a number of users. If you are one of them, keep reading since, along with a few tips on how to retrieve some of the encrypted files without paying a ransom, we have written a comprehensive guide that explains how to remove the malware and clean your computer from other hidden threats.
