How to remove NanoCore RAT from PC?: Installation Guide

Computer security is tested daily by hackers around the world. Companies spend millions on digital security, and consumers can be constantly exposed to malware threats that have evolved into unsafe viruses such as the NanoCore RAT.

Patch updates are always available, but protections in operating systems are under attack. Viruses also penetrate the most advanced techniques. NanoCore RAT quickly penetrates your PC system and destroys it.

What is NanoCore RAT?

NanoCore RAT is a type of malware that misleads the user.

The NanoCore masquerades as a legitimate program. Trojan virus is harmless but dangerous because it allows cybercriminals to enter a user’s system. When a trojan virus activates, it starts spying, collecting valuable data, and sending it to criminals.

In today’s world, there are many more varieties of Trojans. Viruses know how to find their way to a user’s computer to gain full control over it. In addition, the NanoCore RAT collects information about the system to detect vulnerabilities. All the information collected is still used to create ransoms, other viruses, and programs.

Trojan virus detection, especially the NanoCore RAT, is very difficult. It is essential to choose the right antivirus tool such as Armor, to protect your PC.

Symptoms of a NanoCore RAT Attack

The NanoCore RAT hides where it’s hard to find. The Trojan resides on the PC system and secretly spies on users, and conducts other illegal operations.

Since the NanoCore masquerades as a legitimate and safe process, the NanoCore RAT Trojan is difficult to find, but the system shows common specific symptoms that confirm the presence of the virus:

  • The processor suddenly starts consuming more PC system resources than usual.
  • The system freezes frequently and crashes for a long time.
  • Internet browsers constantly show malicious pop-ups.
  • Random windows open by themselves when the user is not waiting.
  • Browser pages move to unreliable or suspicious sites.

How did the NanoCore RAT end up on a user’s PC?

There are hundreds of ways for a virus to enter a computer. Here are the main ones:

  1. The user downloaded a program with a virus and installed it using that program. The software can also be included with NanoCore RAT.
  2. The user opened the infected email, and the virus quickly reached his PC.
  3. A pop-up ad attracted the user, and he clicked on it – NanoCore RAT instantly entered his computer.
  4. The Trojan program, bringing the coveted entry, starts a chain reaction, installing other viruses by itself.
  5. Peer-to-peer networks are the main carrier of NanoCore.

How does NanoCore RAT work?

NanoCore RAT works in the same way as other Trojans, pretending to be a legitimate program, hiding in the system and performing various malicious actions (theft of banking information, passwords, emails, etc.).

The NanoCore RAT copies its executable file to the Windows system folders once installed on the PC. The virus also modifies the registry.

Fake NanoCore RAT file monitoring?

Once a NanoCore RAT file is noticed, there are two ways to check if it is legitimate or fake.

  • The first is the location of the file.
    1. The legitimate file is located in the C:\Windows\System32 folder.
    2. Other files with NanoCore RAT are placed in any other folder except C: Windows\System32.
  • The second option is to use the Task Manager.
    1. Start Task Manager.
    2. See the Processes tab and look for NanoCore RAT.exe.
    3. Right-click on the file – Delete.
    4. Will Windows give you a warning? So the NanoCore RAT.exe process is legitimate. When Windows shows nothing – the NanoCore RAT.exe process is fake.

Remove NanoCore RAT Trojan program from your system

The user may notice that the virus is not fully removed from the system by detecting the NanoCore and removing it. The reason is the infection of the registry with other system files.

Various methods to remove NanoCore RAT from a device:

Method 1: Removing NanoCore RAT via Registry Editor

The trojan modifies the registry, so it is necessary to remove it from the registry using Regedit.

  • Run command line – enter Regedit.
  • Please back up the registry before deleting it. Click File – Export – save the log in a safe place.
  • Once the backup is done, click on Edit – Find.
  • Enter NanoCore RAT.exe – Find next.
  • Once the record is found, right-click – Delete.

First of all, it is necessary to boot the PC in safe mode to prevent the NanoCore from starting:

Windows 7, 10, Vista, XP

Restart your computer + press “F8” when the PC boots up (this must be done before the Windows logo appears).

The “Advanced Options” menu should appear on the screen, where you should go to “Safe Mode with network connection” and press Enter.

Windows 8, Windows 8.1

Press “Windows” + “R” to open the RUN window – enter MSConfig – click OK. Then go to the Boot tab to select Safe Boot and Networking options – click OK – restart your PC.

Method 3: Uninstall all suspicious apps

If a NanoCore RAT scam always appears on your PC, you need to find the culprit application to successfully remove it.

Right-click on the taskbar – choose Task Manager – watch the applications that consume system memory – among the applications perhaps those that have not been installed and run by the user – now right-click on applications suspects to open the file location – uninstall the file.

Open Control Panel – click Remove Program – check for suspicious applications – remove them.

Method 4: Remove Temporary Files

The temporary files folder is often a host for malicious files. It is recommended to remove temporary files and folders normally to keep your PC system running smoothly.

  1. Open the Run command window
  2. Start %temp% – Login
  3. You will see the path C:\Users\[username]\AppData\Local\Temp – this is the temporary folder
  4. Select here each file and folder to delete them
  5. Completely clear the trash
