Relock ransomware removal instructions
What is Relock?
First discovered by malware security researcher, Dmitriy Melikov, Relock is a new variant of a ransomware-type virus called Matrix. Once infiltrated, Relock encrypts stored data (from this point files become unusable) and adds the "_[RELOCK001@TUTA.IO].*" extension to each filename. For instance, "sample.jpg" is renamed to "sample.jpg_[RELOCK001@TUTA.IO]" or "sample_[RELOCK001@TUTA.IO].jpg". Immediately after encryption, Relock generates a "!OoopsYourFilesLocked!.rtf" file and places it in each existing folder. It also changes the desktop wallpaper.
The new .rtf file provides detailed information regarding the current situation together with decryption instructions. It states that the files are encrypted using a strong algorithm and that decryption requires a unique key. Unfortunately, this information is accurate. It is currently unknown whether Relock uses symmetric or asymmetric cryptography, however, in any case, a decryption key is generated uniquely for each victim (restoring files without this key is impossible). Criminals store these keys on a remote server. Therefore, the message presented in the .rtf file encourages users to contact Relock's developers (via one of the email addresses provided) and pay a ransom. It is also stated that victims must do this within seven days following encryption, otherwise the keys are permanently deleted and restoring files becomes impossible. Users are also allowed to attach up to three files (max 5 MB in total), which are decrypted and returned as a 'guarantee' that restoring is possible. The cost is currently unconfirmed, since we did not attempt to contact these people, however, this type of scam usually demands $500-1500 in Bitcoins. Despite the threats, never trust cyber criminals, no matter how low the cost. These people often ignore victims after payments are submitted. There is no guarantee that paying will give any positive result and you will probably be scammed. Therefore, never attempt to contact these people or send any money - you will lose your money and support cyber criminals. Unfortunately, there are no tools capable of restoring files encrypted by Relock. The only solution is to restore system/data using a backup file.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
There are dozens of ransomware-type viruses similar to Relock, including Hacking, Decoder, Hermes, SyncCrypt, and Paradise. Research shows that, although these viruses are developed by different cyber criminals, their behavior is identical. All encrypt data and make ransom demands. They have just two major differences: 1) size of ransom, and; 2) type of cryptography used. Unfortunately, most ransomware employs algorithms that generate unique decryption keys (for example, AES, RSA, etc.) Therefore, users are unable to restore files manually (without developers involvement), unless the malware is not fully developed or has certain flaws (e.g., the key is hard-coded or stored in a local file). Relock and other ransomware-type viruses present a strong case for maintaining regular data backups. Bear in mind, however, that backups 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?
This situation can be prevented by paying close attention when browsing the Internet. Never open files received from suspicious email addresses. In fact, these emails should be deleted immediately, without reading. Furthermore, download your apps from official sources only using a direct download link. Note that third party download/installation tools are monetized by promoting malicious programs. Therefore, such tools should never be used. Keeping installed applications updated and using a legitimate anti-virus/anti-spyware suite is also very important. Bear in mind, however, that ransomware is often proliferated using fake updaters, and so we highly recommend you to update software only via official tools or an implemented "Update" feature. 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 Relock 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 Relock 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 Relock 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 Relock 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.
