MCrypt2018 virus Removal Guide

What is MCrypt2018 ransomware?

MCrypt2018 ransomware is a cyber threat that can also be named CRP.Net3 ransomware

MCrypt2018 ransomware virusMCrypt2018 ransomware is a cyber threat that makes a lot of changes on the computer to keep virus persistent on the system. MCrypt2018 ransomware is a cryptovirus that encrypts data using DiskCryptor functionality and then demands to contact the developer. This threat can also be called CRP.Net3 because the main executable of this virus is called CRPDOTNET3.exe. Similarly to HDDCryptor, Bad Rabbit, MBR-ONI and other crypto viruses, the ransomware does not encrypt data[1] but locks the whole drive using the DiskCryptor utility, so there is no file appendix added to the locked files. The so-called encryption is followed by the note which is placed on the system when the user restarts the device. Then, the black window is displayed in the message stating nothing more than a suggestion to contact the criminals behind ransomware via email address. In most cases, criminals seek to trick their victims to pay the ransom for the alleged file recovery key. However, paying the ransom as well as contacting virus developers can lead to permanent money or data loss, so you shouldn't do that.

When it comes to the main functionality of ransomware viruses, it becomes clear that MCrypt2018 virus is not such a typical cryptovirus. There is no specific encryption algorithm used to encrypt data, no file extension or ransom note – main features used by widely-spread ransomware. This particular cyber threat locks the whole disk by using DiskCryptor[2] for the process. This utility is an open-source system that allows virus developer to lock an entire hard drive of the infected device. This tool is based on the AES-256 encryption algorithm but often employs a combination of a few different methods.

When MCrypt2018 ransomware virus infiltrates the system, it starts changing various parts of the system to keep the payload running on the device undetected for as long as possible. Ransomware can alter registry entries and place various files on the system. Data associated with this ransomware includes the following:

  • the main CRPDOTNET3.exe;
  • netpass.txt;
  • mount.exe;
  • dcapi.dll;
  • dcrypt.exe;
  • log_file.txt ;
  • netuse.txt.;
  • etc.

Additionally, MCrypt2018 ransomware encrypts the whole hard disk and lets you know about itself only the process is finished and your data on that disk is fully locked. The rebooted device displays the black window with the following ransom message:

You have Been Hacked, the ALL the Data the Encrypted, Key Contact For
Our Email:
YourID: [executable name]
Your the Hostname: [computer name]
the Enter Key:

Ransomware loads the direct malicious file on the PC from a spam email attachment

Spam email campaigns nowadays can be used in a wide range of cyber attacks. That include ransomware infiltrations also. People get emails every day and not paying attention may lead to scams, malware or ransomware infections. The email that delivers malicious files to your system may look legitimate and useful because malicious actors employ various deceptive techniques of malware distributing.

The most common thing about insecure emails that you can notice is the misuse of well-known company names or services. People tend to open these commonly found emails without much thought but then the “financial information” attachment distributes unwanted content the minute you download a safe-looking document on the system.

You should try scanning the MS Excel or Word documents attached to suspicious emails first before opening them on the computer. Then you can be sure there is nothing malicious about the file. Also, be aware that services are not sending order information or receipts for non-customers and these emails rarely contain grammar mistakes or typos.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove MCrypt2018 from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by MCrypt2018, you can use several methods to restore them:

You should try to restore your data using Data Recovery Pro if you have no backups on the external device

Data Recovery Pro is a tool that can be used after a ransomware attack. It also recovers your accidentally deleted data

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by MCrypt2018 ransomware;
  • Restore them.

Windows Previous Versions feature is another alternative for file recovery

You could restore your files after MCrypt2018 ransomware encryption using Windows Previous Versions if System Restore was enabled before the attack

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Benefits of the file recovery using ShadowExplorer

If Shadow Volume Copies remain on the system, you can restore your files encrypted by the ransom-demanding virus

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;

Decryption is not possible

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from MCrypt2018 and other ransomwares, use a reputable anti-spyware, such as FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
