If you are a Norton user, you might have encountered the NSC.exe application error at some point. This error usually happens when you try to launch Norton or run a scan. It can be frustrating and annoying, especially if you rely on Norton to protect your computer from viruses and malware.

NSC.exe is a process that belongs to Norton Security Suite, a product of Symantec Corporation. It stands for Norton Security Center, and it is responsible for displaying the status and notifications of Norton on your system tray. It also allows you to access the Norton settings and features from the system tray icon.

The process is not a virus or malware but a legitimate component of Norton. However, sometimes it can cause problems and interfere with the normal functioning of Norton.

You can fix this error and get your Norton antivirus working again in several ways. In this article, we’ll talk about the NSC.exe application error and how to fix it.

What causes the NSC.exe application error?

You might see the NSC.exe application error on your screen for several reasons. Some of the common ones are:

  • Corrupted or missing NSC.exe file: If the NSC.exe file is damaged or deleted by mistake, it can prevent Norton from launching or scanning properly.
  • Outdated or incompatible Norton version: If you are using an old or incompatible version of Norton, it might not work well with your computer’s operating system or other software. This can cause conflicts and errors.
  • Malware infection: If a virus or malware infects your computer, it might corrupt or delete the NSC.exe file or other Norton files. It might also block Norton from running or scanning.
  • Registry issues: If your Windows registry is corrupted or contains invalid entries related to NSC.exe or Norton, it can cause errors and crashes.

How to fix the NSC.exe application error?

Although there are no exact fixes to the problem and the company is yet to announce any measures, you will have to perform some general fixes, which are as follows:

Restart your computer

Sometimes, a simple restart can solve many problems on your computer. It can clear the temporary files and cache that might be causing the error. It can also refresh the system processes and services that might be malfunctioning.

Update your Norton

If you are using an outdated or incompatible version of Norton, you should update it to the latest version available. This can fix any bugs or issues that might be causing the error. You can update your Norton from the system tray icon or the Norton website.

Run Norton LiveUpdate

If updating your Norton does not fix the error, you should run Norton LiveUpdate to download and install the latest patches and definitions for your Norton. This can improve the performance and security of your Norton and fix any errors. You can run Norton LiveUpdate from the system tray icon or the Norton main window.

Disable Fast Startup

Fast startup is a feature that speeds up the boot process of Windows 11 by saving some system information to a file when you shut down your computer. However, this feature can also cause problems, such as the NSC.exe application error. Thus, disabling this feature may help in solving many errors.

Uninstall and reinstall your Norton

If running Norton LiveUpdate does not fix the error, uninstall and reinstall your Norton completely. This can remove any traces of corruption or infection that might be causing the error.

You can uninstall your Norton from the Control Panel or the Norton Remove and Reinstall tool. After uninstalling, you should download and install a fresh copy of Norton from the website.

We hope that by following the above steps, you can easily fix the NSC.exe application error.
