Nwjs is a malicious program that uses stealth to enter the computer, and once within it, starts executing a series of harmful tasks. Security researchers recognize Nwjs as a Trojan horse and recommend that users remove it quickly before it does them a lot of harm.


It is reported that Nwjs attacks mainly Windows computers with the idea to perform various illegal activities in them without the victim’s knowledge. This Trojan represents a sophisticated piece of malware that typically uses spam, malicious email attachments, fake pop-up notifications, torrents, and compromised program installers to distribute itself across the web. In most cases, the Trojan is camouflaged as an intriguing offer, a web link, or a seemingly harmless file but as soon as the user clicks on it, the malware is secretly injected into the computer.

Please follow all the steps below in order to remove Nwjs!

How to remove Nwjs

  1. First, click the Start Menu on your Windows PC.
  2. Type Programs and Settings in the Start Menu, click the first item, and find Nwjs in the programs list that would show up.
  3. Select Nwjs from the list and click on Uninstall.
  4. Follow the steps in the removal wizard.

What we suggest you do first is, check the list of programs that are presently installed on the infected device and uninstall any rogue software that you find there:

  • From the Start Menu, navigate to Control Panel ->>> Programs and Features ->>> Uninstall a Program.
  • Next, carefully search for unfamiliar programs or programs that have been installed recently and could be related to Nwjs.
  • If you find any of the programs suspicious then uninstall them if they turn out to be linked to Nwjs.
  • If a notification appears on your screen when you try to uninstall a specific questionable program prompting you to just alter it or repair it, make sure you choose NO and complete the steps from the removal wizard.

Remove Nwjs from Chrome

  1. Click on the three dots in the right upper corner
  2. Go to more tools
  3. Now select extensions
  4. Remove the Nwjs extension
  • Once you open Chrome, click on the three-dots icon to open the browser’s menu, go to More Tools/ More Options, and then to Extensions.
  • Again, find the items on that page that could be linked to Nwjs and/or that might be causing problems in the browser and delete them.
  • Afterwards, go to this folder: Computer > C: > Users > *Your User Account* > App Data > Local > Google > Chrome > User Data. In there, you will find a folder named Default – you should change its name to Backup Default and restart the PC.
  • Note that the App Data folder is normally hidden so you’d have to first make the hidden files and folders on your PC visible before you can access it.

How to get rid of Nwjs on FF/Edge/etc.

  1. Open the browser and select the menu icon.
  2. From the menu, click on the Add-ons button.
  3. Look for the Nwjs extension
  4. Get rid of Nwjs by removing it from extensions

If using Firefox:

  • Open Firefox
  • Select the three parallel lines menu and go to Add-ons.
  • Find the unwanted add-on and delete it from the browser – if there is more than one unwanted extension, remove all of them.
  • Go to the browser menu again, select Options, and then click on Home from the sidebar to the left.
  • Check the current addresses for the browser’s homepage and new-tab page and change them if they are currently set to address(es) you don’t know or trust.

If using MS Edge/IE:

  • Start Edge
  • Select the browser menu and go to Extensions.
  • Find and uninstall any Edge extensions that look undesirable and unwanted.
  • Select Settings from the browser menu and click on Appearance.
  • Check the new-tab page address of the browser and if it has been modified by “Nwjs” or another unwanted app, change it to an address that you’d want to be the browser’s new-tab page.

How to Delete Nwjs

  1. Open task manager
  2. Look for the Nwjs process
  3. Select it and click on End task
  4. Open the file location to delete Nwjs
  • Access the Task Manager by pressing together the Ctrl + Alt + Del keys and then selecting Task Manager.
  • Open Processes and there try to find a process with the name of the unwanted software. If you find it, select it with the right button of the mouse and click on the Open File Location option.
  • If you don’t see a “Nwjs” process in the Task Manager, look for another suspicious process with an unusual name. It is likely that the unwanted process would be using lots of RAM and CPU so pay attention to the number of resources each process is using.
  • Tip: If you think you have singled out the unwanted process but are not sure, it’s always a good idea to search for information about it on the Internet – this should give you a general idea if the process is a legitimate one from a regular program or from your OS or if it is indeed likely linked to the adware.
  • If you find another suspicious process, open its File Location too.
  • Once in the File Location folder for the suspicious process, start testing all of the files that are stored there by dragging them to our free online scanner available below.
  • Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
    This scanner is free and will always remain free for our website's users.
    This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    • If the scanner finds malware in any of the files, return to the Processes tab in the Task Manager, select the suspected process, and then select the End Process option to quit it.
    • Go back to the folder where the files of that process are located and delete all of the files that you are allowed to delete. If all files get deleted normally, exit the folder and delete that folder too. If one or more of the files showed an error message when you tried to delete them, leave them for now and return to try to delete them again once you’ve completed the rest of the guide.

    How to Uninstall Nwjs

    1. Click on the home button
    2. Search for Startup Apps
    3. Look for Nwjs in there
    4. Uninstall Nwjs from Startup Apps by turning it off
    • Now you need to carefully search for and uninstall any Hostingcloud. racing-related entries from the Registry. The easiest way to do this is to open the Registry Editor app (type Regedit in the windows search field and press Enter) and then open a Find dialog (CTRL+F key combination) where you have to type the name of the threat. 
    • Perform a search by clicking on the Find Next button and delete any detected results. Do this as many times as needed until no more results are found. 
    • After that, to ensure that there are no remaining entries lined to Nwjs in the Registry, go manually to the following directories and delete them:
    • HKEY_CURRENT_USER/Software/Random Directory. 
    • HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run/Random
    • HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main/Random
    What is Nwjs?

    The hackers who control the Nwjs trojan dictate its entire behavior and activities and can set it to perform different harmful tasks that may be totally unrelated. In general, this malware is successful in gathering personal information from the infected device. The collection of data can happen in many ways, and one of them is via your own webcam and microphone. The Trojan simply takes audio and video records of the conversations of the victims and their online and offline activities or makes screenshots that are later transferred to remote servers. A malicious piece like Nwjs may also be programmed to collect information about the victim’s contacts and monitor their keystrokes so that it can steal their passwords, user names, additional login credentials or online banking details.

    Is Nwjs a virus?

    A very frightening scenario is where the criminals gain full remote control over the infected computer through the Nwjs virus virus and are able to monitor the entire computer, to install, change, replace, remove or corrupt existing files or execute hidden malicious tasks and processes. In such situations, the infected machine can become a bot – a zombie machine secretly operated by hackers – and can be set to perform different activities that benefit them. For instance, nowadays it is extremely popular for Trojans to exploit the resources of the computers they infect for cryptocurrency mining or the distribution of spam and dreadful viruses like Ransomware or spyware. The effects of such exploitation of the system can be very unpleasant since they may lead to RAM and CPU overload, frequent Blue Screen of Death crashes, software freezing, unresponsiveness, and general instability of the OS. As a result, the victims may end up with a totally useless computer that is unable to run even simple tasks until the Trojan virus is detected and removed.  

    Is Nwjs dangerous?

    However, the detection and the removal of infection like Nwjs is the most difficult part of the whole thing. This is simply because Trojans do not usually have clear symptoms that would give them away. Most of the time, they operate in stealth and can often mimic system files and processes in order to confuse the person who is trying to remove them. That’s why the best way to handle an infection such as Nwjs is to use a professional removal tool, particularly if you are facing a Trojan horse for the first time. A manual removal guide such as the one you will find below is yet another alternative. However, if you do not know exactly which files you have to remove, our advice is to follow the instructions closely and make no experiments.
