RT4BLOCK ransomware removal instructions
What is RT4BLOCK?
RT4BLOCK is high-risk malware categorized as ransomware. Typically, programs of this type block access to data (encrypt files) and keep them locked unless a ransom is paid. RT4BLOCK is a part of the RotorCrypt ransomware family and was discovered by Michael Gillespie. It changes filenames of encrypted files by adding the "!-information-...___ ingibitor366 @cumallover.me ___....RT4BLOCK" string. For example, "1.jpg" is renamed to "1.jpg!-information-...___ firstname.lastname@example.org ___....RT4BLOCK". Like most ransomware-type programs, RT4BLOCK creates a ransom message within a text file, in this case called "NEWS_INGiBiToR.txt".
The "NEWS_INGiBiToR.txt" file contains a note stating that all data is locked and that victims must contact RT4BLOCK's developers via the email@example.com email address immediately, otherwise they will lose their files. It is also stated that any attempts to decrypt files with third party tools (manually) will damage all files permanently. Victims are given 15 days to contact the cyber criminals who developed this ransomware - after this period, all data is deleted. Generally, only ransomware developers have the tools or keys that can decrypt encoded files. Despite this, you are advised not to trust them: victims often do not receive decryption tools/keys, even if they transfer ransom payments (usually, via a cryptocurrency). As there is no free tool capable of decrypting files encoded with RT4BLOCK, the best option is to recover files from a backup (if one was created prior to encryption and it has not been encrypted together with the remaining data).

RT4BLOCK is similar to Ntuseg, Acuf2, UNNAMED, and other ransomware-type malware. Typically, these programs lock/encrypt files and display ransom messages. Two main differences are size of ransom and cryptography algorithm (symmetric or asymmetric) that is used to encrypt files. Locked files cannot be decrypted without the correct tool and the involvement of the cyber criminals who designed the ransomware. To prevent data and financial loss, have your data backed up and store it on remote server or unplugged device.

How to protect yourself from ransomware infections?
To prevent computer infection with ransomware-type and other malicious programs, do not open email attachments or links received from unknown, untrustworthy, or suspicious addresses. Update installed programs via implemented functions or tools provided by official developers. Do not download software from untrustworthy, unofficial websites or using third party downloaders. The safest way to download is using official web pages and direct download links. Activate software with official tools, since 'cracking' tools often cause computer infections and are illegal. Finally, have reputable anti-spyware or anti-virus software installed and enabled at all times. If your computer is already infected with RT4BLOCK, we recommend running a scan with Spyhunter 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 RT4BLOCK 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 RT4BLOCK 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 RT4BLOCK 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 RT4BLOCK 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 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.
