LX ransomware removal instructions
What is LX?
LX is a piece of malicious software, belonging to the Crisis/Dharma ransomware family. Discovery is credited to Jakub Kroustek. It operates by encrypting the data of infected systems, in order to demand payment for the decryption tools/software. As this malware encrypts, all affected files are retitled according to this pattern: original filename, unique ID, cyber criminals' email address and the ".LX". For example, a file like "1.jpg" would appear as something similar to "1.jpg.id-1E857D00.[email@example.com].LX", and so on. Afterwards, a text file - "FILES ENCRYPTED.txt" is created on the desktop and a pop-up window is displayed.
The ransom note in the text file ("FILES ENCRYPTED.txt") informs victims that their data has been "locked" and to recover it, they are instructed to write to the email addresses of the cyber criminals behind the infection. The text presented in the pop-up window provides a bit more information. It clarifies that the victims' files have been encrypted, but it is possible to restore them. To recover the encrypted data, it is repeated that users must initiate communication via email. Their letter must contain the unique ID assigned to them. Should victims receive no response within 12 hours, they are to use the other email address. The note in the pop-up ends with warnings. Users are alerted that renaming the encrypted files and/or attempting to decrypt them with third party tools - may lead to permanent data loss. Unfortunately, in most cases of ransomware infections, without the involvement of the individuals responsible - decryption is impossible. It might be, if the malware is still in development and/or has bugs (flaws). Whatever the case, it is expressly advised against communicating with and/or meeting the ransom demands of cyber criminals. Since often, despite paying - victims do not receive the promised decryption tools/software. Hence, their files remain encrypted and they experience financial losses. To prevent LX ransomware from further encryptions - it must be removed from the operating system. However, removal will not restore already affected data. The only possible solution is recovering it from a backup, if ones was created before the infection and was stored in a different location.

Tongda2000, R44s, DECP, Uzuvnkyh are a few examples of other ransomware-type programs. They are designed to encrypt data and demand payment for the decryption. There are some crucial differences in-between them: the cryptographic algorithm used for the encryption and the size of the demanded ransom. The latter range from three to four digit sums (in USD). Digital currencies (e.g. cryptocurrencies, pre-paid vouchers, etc.) are typically used for these payments, since transactions of them are difficult/impossible to trace. To avoid data loss, it is strongly recommended to keep backups in unplugged storage devices and/or remote servers (ideally, in several separate locations).

|Symptoms||Cannot open files stored on your computer, previously functional files now have a different extension (for example, my.docx.locked). A ransom demand message is displayed on your desktop. Cyber criminals demand payment of a ransom (usually in bitcoins) to unlock your files.|
|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.|
To eliminate malware infections our security researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
It is ill-advised to open suspicious and/or irrelevant emails, especially any attachments (or links) present in them - can result in a high-risk infection. All downloads should be done only from official and verified sources. It is just as important to activate and update software with tools/functions, provided by legitimate developers. Illegal activation ("cracking") tools and third party updaters are often used to proliferate malware. To protect device integrity and user safety, it is crucial to have a dependable anti-virus/anti-spyware installed and kept updated. Furthermore, such programs should be used to run regular system scans and to remove all detected threats/issues. If your computer is already infected with LX, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
Text presented in LX ransomware's pop-up window:
YOUR FILES ARE ENCRYPTED
Don't worry,you can return all your files!
If you want to restore them, follow this link:email firstname.lastname@example.org YOUR ID 1E857D00
If you have not been answered via the link within 12 hours, write to us by e-mail:email@example.com
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 LX 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 LX 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 LX 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 LX 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.
