.java ransomware removal instructions
What is the .java ransomware?
.java is the name of a malicious program, belonging to the Dharma ransomware family. Systems infected with this malware, experience data encryption and receive ransom demands for the decryption. During the encryption process, files are renamed according to this pattern: original filename, unique ID, cyber criminals' email address and ".java" extension (not to be confused with the legitimate ".java" extension of JAVA files). To elaborate on how a file could appear following encryption, then - a file like "1.jpg" would appear as something similar to "1.jpg.id-1E857D00.[firstname.lastname@example.org].java", and so on for all of the affected files. Once this process is complete, a ransom note is presented in a pop-up window and "FILES ENCRYPTED.txt".
The text presented in "FILES ENCRYPTED.txt", informs victims that their data has been locked and to restore it - they must establish contact with the cyber criminals via email. The ransom note in the pop-up window provides more information concerning the infection. It clarifies that all of the files have been encrypted. Additionally, the emails users are to sent - must contain the ID assigned to them (which can be found in the pop-up and modified filenames). The size of the demanded payment is not specified, however it is stated that it will have to be paid in Bitcoin cryptocurrency (the message also contains links to websites detailing how to and from where to obtain Bitcoins). Before paying, decryption can be tested by sending the criminals up to five encrypted files. They will be decrypted and sent back; provided, if the total size of the files does not exceed 10 MB (non-archived) and they do not contain valuable information (e.g. databases, backups, large Excel sheets, etc.). The note is concluded with warnings. Victims are alerted that renaming the encrypted files and/or attempting to decrypt them - may result in permanent data loss. In many cases of ransomware infections, without interference of the cyber criminals responsible - decryption is impossible. It might be, if the malware has significant bugs (flaws) and/or is still in development. Whatever the case, it is expressly advised against meeting the ransom demands. Since often, despite paying - users do not receive the promised decryption tools/software. Therefore, they experience financial loss and their data remains encrypted (essentially, worthless). To prevent .java from further encryptions, it must be removed from the operating system. Unfortunately, removal will not restore already compromised files. The only solution is recovering them from a backup, if one was created prior to the infection and was stored in a different location.

Lxhlp, Zida, .support and WastedLocker are some examples of other malicious programs, classified as ransomware. They operate by encrypting data and demanding payment for the decryption tools/software. There are two key differences between these programs/infections - the cryptographic algorithms they use (symmetric or asymmetric) and the ransom size. These sums tend to range from three to four digits in USD. Digital currencies (e.g. cryptocurrencies, pre-paid vouchers, etc.) are commonly used for the ransoms, due to transactions of them being difficult/impossible to trace. To avoid permanent data loss, it is strongly recommended to keep backups in remote servers and/or unplugged storage devices (ideally, in several separate locations).

|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password-stealing trojans and malware infections can be installed together with a ransomware infection.|
|Malware Removal (Windows)||
To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
How to protect yourself from ransomware infections?
Suspicious and/or irrelevant emails must not be opened, especially any attachments or links found in them - as that can result in a high-risk infection. It is recommended to only use official and verified download channels. Additionally, all products must be activated and updated with tools/functions provided by legitimate developers. Illegal activation tools ("cracks") and third party updaters are advised against use, due to often being used to proliferate malware. To protect device and user safety, it is paramount to have a reputable anti-virus/anti-spyware suite installed. Furthermore, this software has to be kept up-to-date, used to run regular system scans and to remove detected/potential threats. If your computer is already infected with .java, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files.
Free decryption as guarantee
Before paying you can send us up to 5 files for free decryption. The total size of files must be less than 10Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)
How to obtain Bitcoins
The easiest way to buy bitcoins is LocalBitcoins site. You have to register, click 'Buy bitcoins', and select the seller by payment method and price.
Also you can find other places to buy Bitcoins and beginners guide here:
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.

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 .java 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 .java 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 .java 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 .java ransomware.
Note that 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, and 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.
