njRat malware removal guide
What is njRat?
The njRat program is categorized as a Remote Access Trojan (RAT). It usually installs without victims' knowledge, stealthily runs in the background (also without victims' knowledge), and collects various sensitive data. Cyber criminals use a number of methods to trick people into downloading and installing programs of this type.
Cyber criminals use the njRat trojan-type program to gather system information, steal various usernames and passwords, and other personal, sensitive details. Additionally, it can be used to download and install malicious software. Generally, these programs send all collected data to remote servers that are controlled by cyber criminals. Stolen/recorded data might be used for blackmail purposes or to generate revenue in other ways. By having access to various personal accounts, cyber criminals can cause privacy problems or even financial loss for the victims. If used to download malicious programs, njRat might download ransomware-type viruses that are often used to block access to files stored on computers unless ransoms are paid. If there is any reason to believe that njRat is installed on your system, remove it immediately, otherwise, it can lead to various problems with data/financial loss and additional computer infections.

njRat is similar to other tools of this type such as ExileRat, Nymeria, Remcos, NanoCore, and RMS. They might be distributed by different cyber criminals, however, the consequences of having these programs installed are serious problems. If installed, njRat runs a process in Task Manager (screenshot below) called "t1uT3wb0.exe". Suspicious processes running in Task Manager are usually malicious programs.

How to avoid installation of malware?
If an email is received from an unknown or suspicious address, do not open attached files or included website links. Software should not be downloaded from unofficial websites, using third party downloaders, Peer-to-Peer networks, or other similar sources. The safest way to download is using official websites and direct links. The same applies to software updates: installed programs should be updated using implemented functions or tools provided by official software developers (not third party tools/fake updaters). Software 'cracking' tools are illegal and often cause computer infections. Therefore, they should never be trusted or used. To prevent computer infections, have a reputable anti-spyware or anti-virus suite installed and keep it enabled. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
