NMCRYPT ransomware removal instructions
What is NMCRYPT?
NMCRYPT is a high-risk ransomware-type virus similar to NM4. Once infiltrated, NMCRYPT encrypts most stored data using AES-256 and RSA-2048 encryption algorithms. In addition, this malware appends filenames with the ".NMCRYPT" extension. For example, "sample.jpg" is renamed to "sample.jpg.NMCRYPT". Encrypted files become unusable. Once the encryption process is over, NMCRYPT generates an HTML file ("Recover your files.html") and places a copy in every existing folder.
The new HTML file contains a long text message informing victims of the encryption and instructing them what to do next - to decrypt data, users must visit NMCRYPT's website and follow the instructions. As mentioned above, NMCRYPT uses AES and RSA algorithms to encrypt data. Therefore, two unique keys (generated individually for each victim) are necessary to restore data. These keys are stored on a remote server controlled by cyber criminals and users are encouraged to pay a ransom in exchange for their release. The cost is $6705.02 and must be paid in the Bitcoin cryptocurrency. As compared to other ransomware-type viruses, the size of this ransom is extremely high - ransoms typically fluctuate between $500 and $1500. Users are also permitted to send three selected files (DOC/XLS/XML/JPG formats, 2MB in total) to cyber criminals. These are then restored and returned to the victim as a 'guarantee' that decryption is possible. In fact, cyber criminals can never be trusted. Research shows that users are often ignored after submitting payments. Paying gives no positive result and users are scammed. Therefore, you are strongly advised to ignore all requests to pay any ransoms. Unfortunately, there are no tools capable of cracking AES/RSA algorithms and restoring files free of charge. Therefore, the only solution is to restore everything from a backup.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
NMCRYPT is virtually identical to Tron, Iron, Vurten, ScorpionLocker, and dozens of other ransomware-type viruses. All are designed by different cyber criminals, however, their behavior is identical - all encrypt data and make ransom demands. In most cases, ransomware-type viruses have just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, most of these viruses employ algorithms that generate unique decryption keys. Therefore, unless the ransomware is not fully developed or has certain bugs/flaws (for example, the key is stored locally, hard-coded or similar), file decryption manually without involvement of developers (contacting these people is not recommended) is impossible. Malware such as NMCRYPT is one of the main reasons why you should keep regular data backups, however, store them on a remote server (e.g., Cloud) or unplugged storage device. If not, backups are encrypted as well.

How to protect yourself from ransomware infections?
To prevent system infiltration by ransomware, be very cautious when browsing the Internet. Think twice before opening email attachments. If the file has been sent by a suspicious email address and it seems irrelevant, do not open it and immediately delete the message. We recommend that you download your applications from official sources only, using direct download links rather than third party downloaders/installers. These tools often include malicious apps, and thus should never be used. Keep installed applications updated and use a reputable anti-virus/anti-spyware suite, but update your apps using implemented functions or tools provided by the official developer only - as mentioned before, criminals proliferate malware using fake updaters. The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution.

I will send you a private key so you can retrieve your files as soon as a donation to complete, if necessary, I will assist you with the procedure. I do not care about your files just with a donation. If your files are important to you, I'll do an evaluation, otherwise you can not retrieve them.
I will provide the private key for you to recover your files.
In addition, you need to make a donation of USD 6,705.02 in bitcoin, converting at the current quotation you need to pay 1.0000 Bitcoin
You can check the price of bitcoin at the following site:
Only donation will be accepted by BITCOIN, but you have no idea how to buy bitcoin on the internet, you can get help in the menu FAQ Click Here
As a guarantee, send up to three files encrypted as DOCS XLS XML JPG.
With a maximum size of 2mb to make it easy you need to compress the files with winrar or zip.
You should upload the files to any upload site of your choice, you do not know of any that you can use the following site
Choose the file and click "Upload File" for the uploaded file.

Log in to the account infected with the NMCRYPT virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.
If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.
Video showing how to remove ransomware virus using "Safe Mode with Command Prompt" and "System Restore":
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 NMCRYPT 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 NMCRYPT 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 NMCRYPT 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 NMCRYPT 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.
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.
