What Is NRCL Virus?

NRCL-ransomware-virus-removal-guide-sensorstechforum

The name NRCL belongs to a cryptovirus that has been released in the wild to infect computer systems and encode personal files. The activation of the payload file of this ransomware on an operating system sets the beginning of a complex attack consisting of a few stages.

The ransomware is associated with a malicious extension of the same name. The same extension appears at the end of the original names of all corrupted files. Two ransom messages are part of the NRCL virus infection as well. Both messages try to convince victims to contact hackers in order to obtain a decryption tool.

NRCL virus could apply system settings changes that make it a persistent threat. Hence, its complete removal may demand some specific computer skills. Note that the removal of the NRCL virus won’t restore encrypted files. Still, it is mandatory to get rid of all malicious files in order to use the infected computer in a secure manner again.

NRCL Virus – How Did I Get Infected?

NRCL ransomware threat may have landed on your machine without any unusual processes that can reveal it and make you stop on time.

Data locker ransomware are usually propagated via methods that allow hackers to hide the malicious code in commonly used files. The main method used by hackers is direct email messages.

This method is also called malspam or malicious spam email messages. By releasing mass email campaigns with malicious software inside the spam emails, hackers could sometimes spread the malware around the globe.

Other methods that may deliver NRCL ransomware on PCs are the well-known malvertising, modified installers of various freeware, corrupted websites, compromised software setups, fake software updates, malicious files shared on forums, and others.

NRCL Ransomware – What Does It Do?

NRCL ransomware is a malicious program developed to modify essential system settings that lower security, diminish performance and help it to reach a data encryption phase. Each computer system infected with the NRCL virus remains extremely vulnerable to further malware attacks for as long as the ransomware is running on it.

The moment the virus ends the encryption of personal files, a process which is conducted with the help of a strong algorithm, it shows a pop-up ransom note by loading the file NRCL_Decryptor.exe. A second ransom message may be found in the file Note.txt. Apparently, hackers try to force victims to contact them via the email address shown below and then pay a ransom fee of $300. Beware that the decryptor they have for .NRCL files may be broken or missing.

NRCL_Encryptor pop-up ransom note

Here is what the pop-up ransom note says:

Q: Can I Recover My PC?
A: Sure. But you must pay $300.

Q: How Do I Pay?
A: Please send e-mail: test.test@gmail.com.

A: Your Computer was locked by NRSC.exe.

Q: Can I Recover My PC?
A: Sure. But you must pay $300.

Q: How Do I Pay?
A: Please send e-mail: test.test@gmail.com.

Most of the ransomware infections including the recently detected STOP ransomware strains Utjg Virus and Futm Virus rename all files they corrupt. NRCL ransomware is not an exception.

It uses an extension of the same name to rename compromised files. When the ransomware encodes certain personal files it limits access to the information they store.

Unfortunately, the virus is likely to delete all Shadow Volume Copies created by the Windows system as well. This operation will prevent you from using this option to recover .NRCL files. A recent backup on an external drive or cloud platform could recover the files for free.

.NRCL Files – What Are They?

Below are all of the types of files that may be locked by this nasty ransomware. They all may store valuable data.

  • Image files.
  • Audio files.
  • Document files.
  • Video files.
  • Backup files.
  • Banking credentials, etc.

Here is how files encrypted by NRCL ransomware are renamed:

For the sake of your personal and PC security, refrain from acting as hackers expect you to do. All the money they receive from ransom fees will stimulate them to create new malicious programs and launch even more aggressive malware campaigns.

Please act wisely and try to solve the problem with the help of the available security measures.

Remove NRCL Ransomware and Try to Restore Files

What should you do when your PC and data have been hit by NRCL ransomware? Here we will present the secure way to deal with NRCL ransomware and similar infections. First, you have to ensure that no malicious files are still running on the infected operating system. For this purpose, you need to locate these malicious files and entries and remove them. This will prevent them from causing an impact on regular system performance.

Once you secure the system against nasty ransomware operations, you should back up encoded files to an external drive. Finally, you can proceed with the data recovery process. In the guide below we included alternative data recovery methods that may be efficient for some of your locked files. Bear in mind that these methods may be helpful to some degree. They do not guarantee the full recovery of all encoded files.

In the event that we spot a release of a free decryption tool for NRCL ransomware, we will include all needed details in this ransomware removal guide. Keep in touch.
