RedRum ransomware removal instructions
What is RedRum?
RedRum encrypts files, rendering them inaccessible unless victims recover them with decryption software and keys that can purchased from the cyber criminals who designed this ransomware. RedRum renames all encrypted files by adding the victim's ID and email@example.com email address to their filenames and appending the ".redrum" extension. For example, "1.jpg" might be changed to "1.jpg.id-1E857D00. [Moncler@tutamail.com] .redrum" or similar (updated variants append ".thanos" and ".grinch" extensions). It also stores ransom messages in the form of text files (named "decryption.txt") in all folders that contain encrypted files.
The "decryption.txt" text file states that victims must contact cyber criminals via the firstname.lastname@example.org (or email@example.com) email address and provide the appointed ID. They are encouraged to do so immediately, since, once 60 hours after encryption has passed, the cost of decryption software and key will increase by 10% per day. The cost of the decryption tools is unknown, however, it is made clear that decryption without them is impossible. Victims supposedly receive these assets after payment, however, you are not advised to trust or pay any cyber criminals (ransomware developers) - they often send no decryption tools, even if victims meet all demands. Only the people who develop ransomware (in this case, RedRum) hold tools that can decrypt files encrypted by the program. Typically, the only way to avoid being scammed and recover files without making payment is to restore them from an existing backup. Removal of the ransomware does not decrypt files, it simply prevents the malware from causing any further encryption.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Most ransomware-type programs are similar: they encrypt files and keep them inaccessible unless a ransom is paid (decryption software and/or key is purchased). Common differences are usually cost of decryption, and cryptographic algorithm (symmetric or asymmetric) used to encrypt/lock data. Unfortunately, files cannot be recovered without specific tools held by the developers of the ransomware, unless the ransomware is not fully developed, contains bugs/flaws, etc. Therefore, have data backed up and keep it on a remote server and/or unplugged storage device. Examples of other ransomware are Bobelectron, Nbes and DMR64.

How to protect yourself from ransomware infections
Do not download files or programs from unofficial web pages or other dubious sources (mentioned above). Download only from official websites and via direct download links. Do not trust emails that contain attachments (and/or web links) and are received from unknown, suspicious addresses. Note that malicious attachments/files cannot do any harm if they are left unopened. Installed software should be updated using tools and/or implemented functions that are designed by official software developers. The same applies to activation of licensed software. Various unofficial ('cracking') tools are illegal and are often designed to distribute and install malware. It is also important to regularly scan the operating system with reputable antivirus or anti-spyware software. Keep these programs up to date. If your computer is already infected with RedRum, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

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 RedRum 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 RedRum 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 RedRum 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.
