Random Ransom ransomware removal instructions
What is Random Ransom?
Random Ransom was discovered by S!Ri. It encrypts files, modifies their filenames and displays a pop-up window with a note in it. Random Ransom changes encrypted files by appending the ".RANDOM" extension to their filenames. For example, it renames a file named "1.jpg" to "1.jpg.RANDOM", "2.jpg" to "2.jpg.RANDOM", and so on. In order to be restore (decrypt files) victims have to follow the instructions in a pop-up window.
As explained in a pop-up window ("RANDOM_RANSOM_DECRYPTOR"), victims supposed to be able to decrypt files by playing a game that can be launched by clicking the "PLAY GAME" button. Victims have to score 50 points in one hour, after that Random Ransom's developers will delete a decryption key and it will not be impossible to recover files anymore. Unlike most cyber criminals, Random Ransom's developers do not demand to be paid or contacted. Even if they would, it should not be done. It is because victims who pay a ransom often get scammed, in other words, cyber criminals do not send a decryption tool and/or key even after a payment. Unfortunately, there are no tools that could decrypt files encrypted by Random Ransom, at least not at the moment. In most cases cyber criminals are the only ones who have tools that can decrypt files encrypted by their ransomware. Usually the only free way to decrypt files is to restore them from a backup. It is worthwhile to mention that files remain encrypted even if victims uninstall ransomware from a computer, however, its uninstallation prevents if from causing further encryptions.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Typically ransomware is designed to encrypt files and so that victims could not access them without having to use tools that can be purchased only from cyber criminals, and create and/or display some ransom note (or notes). Two main and most common variables are price of a decryption tool and/or key and cryptographic algorithm (symmetric or asymmetric) that ransomware uses for encryption. Unfortunately, files can be decrypted for free only when ransomware is not finished (has bugs, flaws, and other vulnerabilities) and this does not happen often. That is why it is so important to always have data backed up and keep it on a remote server and/or unplugged storage device. Here are some examples of other ransomware: Revon, CCD and encS.

How to protect yourself from ransomware infections?
Received emails that contain attachments (and/or website links), are sent from unknown, suspicious addresses should not be trusted. In other words, email contents should be opened only when there is no reason to believe that it may cause installation of malware or other issues. software should never be downloaded from untrustworthy, unofficial websites, via third party downloaders and other channels of this kind. Files and programs should be downloaded only from official websites and through direct links. Furthermore, installed programs must be updated and activated by using implemented functions and/or tools that are designed by official developers. Third party, unofficial tools can are often used to distribute unwanted, and even malicious programs. Besides, it is not legal to bypass activation of licensed software by using various unofficial ('cracking') tools. And finally, it is recommended to regularly scan the operating system with reputable anti-spyware or antivirus software and always remove detected threats as soon as possible. If your computer is already infected with Random Ransom, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

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 Random Ransom 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 Random Ransom 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 Random Ransom 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 Random Ransom 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.
