jCandy ransomware removal instructions
What is jCandy?
Discovered by malware security researcher, JAMESWT, jCandy is a ransomware-type virus designed to stealthily infiltrate the system and encrypt most stored data. During encryption, jCandy appends filenames with the ".Locked-jCandy" extension (e.g., "sample.jpg" is renamed to "sample.jpg.Locked-jCandy"). From this point, files become unusable. Immediately after encryption, jCandy opens a pop-up windows and places a text file ("JCANDY_INSTRUCTIONS.txt") on the desktop.
The pop-up and text file contain similar messages informing victims of the encryption and demanding a ransom payment. Although it is currently unknown whether jCandy uses symmetric or asymmetric cryptography, we can confirm that decryption requires a unique key. Cyber criminals store this key on a remote server and demand a ransom payment to receive it. The cost of the key is $200 in Bitcoins. It is also stated that payment must be submitted within 48 hours after decryption, otherwise the files are permanently deleted. Despite this, cyber criminals cannot be trusted. Research shows that these people are likely to ignore victims, once the ransoms are paid. Even if the victim decides to support these people by paying the ransom, there is no guarantee that the files will be restored. Victims will probably be scammed. Therefore, we strongly advise you to ignore cyber criminals and never attempt to contact them or pay any ransoms. Unfortunately, there are currently no tools capable of restoring files encrypted by jCandy and you can only restore your files/system from a backup.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
There are dozens of ransomware-type viruses virtually identical to jCandy. The list of examples includes (but is not limited to) Jhash, SIGMA, Xorist, Onion3Cry, and Jigsaw. Bear in mind that, although these viruses are developed by different cyber criminals, they have identical behavior - all encrypt data and make ransom demands. Research shows that there are just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, most ransomware employs algorithms that generate unique decryption keys. Therefore, unless the malware is not fully developed or has certain flaws (for example, the key is hard-coded, stored locally, etc.), it is impossible to restore files manually, without developers' help. For these reasons, jCandy and other ransomware-type viruses present a strong case for maintaining regular data backups. Bear in mind also that backup files must be stored on a remote server (such as Cloud) or an external/unplugged hard drive, otherwise they will also be encrypted.

How to protect yourself from ransomware infections?
To prevent ransomware infections, be very cautious when browsing the Internet. Never open any attachments received from suspicious email addresses - these emails should be deleted without reading. In addition, download your software from official sources only and, preferably, using a direct download link (third party downloaders/installers often include dubious apps). Keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite, however, as mentioned above, criminals proliferate ransomware via fake updaters. Therefore, we strongly advise you to use an implemented "Update" feature or a tool provided by the official developer. The key to computer safety is caution.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the jCandy ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining jCandy ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of jCandy are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as jCandy ransomware.
Note that the Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
