Hello @Larry_Tolman

A Blue Screen of Death (BSOD) during a file scan happens because antivirus software operates at a very deep system level, within the Windows kernel, and any conflict at this level can cause the entire operating system to crash.
Here is a breakdown of why this interaction is a sensitive process and can lead to a BSOD:
- Kernel-Level Access
Antivirus programs need special, elevated permissions to effectively monitor, intercept, and scan all system operations, including low-level drivers and memory access, to detect and neutralize stealthy threats like rootkits. This is done by running components in the Windows kernel mode. When software runs in kernel mode, any critical error or incompatibility it encounters can cause a fatal system error (BSOD) because the operating system cannot recover safely.
- Driver Conflicts
BSODs are most often caused by faulty or incompatible device drivers. Antivirus software installs its own filter drivers to intercept file access requests in real-time. When Norton’s driver interacts with other drivers (like those for your graphics card, storage drive, or the specific game’s anti-cheat software), an incompatibility can cause a conflict that the system cannot resolve, leading to a crash.
- File System Interaction
During a deep scan, the antivirus software rapidly reads numerous files, including the game’s executable (.exe) and associated data files (like those from Unreal Engine 5). This intensive disk I/O puts a heavy load on your storage drive and file system. If there is underlying file system corruption or a problem with your SSD/HDD, the scan might trigger a critical error that forces Windows to shut down.
- Memory Management Issues
The scanning process uses system memory (RAM) and can involve memory-intensive operations, such as emulating code to check for viruses. If there is a problem with your computer’s RAM or how memory is being managed, the antivirus’s access to specific memory pages can trigger errors like PAGE_FAULT_IN_NONPAGED_AREA or MEMORY_MANAGEMENT, resulting in a BSOD.
- Resource Contention
When you hit “Play” on Steam, the game engine (Unreal Engine 5 in this case) and Norton File Insight are both trying to access the same files simultaneously. This resource contention can create a race condition or deadlock, where neither process can proceed, causing the system to lock up and crash.
Summary
The BSOD isn’t necessarily Norton’s fault alone, but rather an indication that the intensive process of an antivirus scan, combined with the launch of a new, potentially resource-intensive game executable, is exposing an underlying instability, likely a driver conflict or a hardware/file system issue.
The fact that the issue resolved itself after Norton had fully analyzed the file and deemed it safe suggests the initial “first-run” scan was the specific trigger point. Adding an exclusion for the game file within Norton’s settings may prevent this in the future.

It appears your Windows 10 Blue Screen of Death (BSOD) events are specifically triggered by the interaction between the Norton File Insight scanner and the execution of newly downloaded game executables from Steam, likely involving game engines like Unreal Engine 5. This suggests a potential software conflict or incompatibility, rather than a hardware issue with your PC.
Here are steps you can take to troubleshoot and resolve this issue:
- Update/Reinstall Relevant Software
Outdated or corrupted drivers and software are the most common causes of BSODs.
- Update Windows: Ensure your Windows 10 operating system is fully up to date via Windows Update.
- Update Graphics Drivers: Visit the website for your graphics card manufacturer (NVIDIA, AMD, or Intel) to download and install the latest drivers.
- Update Norton: Manually check for updates within the Norton client to ensure you have the latest version and definitions. You may also want to use the Norton Remove and Reinstall Tool to perform a clean installation of the security software.
- Update Steam: The Steam client usually updates automatically, but you can manually check for client updates within the application.
- Configure Norton Exclusions
If the issue is a conflict between Norton’s real-time scanning and the game execution process, you can configure Norton to ignore the specific game executables and their installation folders.
- Navigate to your Norton settings and add exclusions for the problematic game folders or executables. Refer to the Norton support documentation for detailed instructions on adding exclusions.
- Analyze the BSOD Error Code
The blue screen usually displays a “Stop Code” (e.g., KERNEL_DATA_INPAGE_ERROR, SYSTEM_SERVICE_EXCEPTION). This code is crucial for identifying the underlying cause.
- After the next BSOD, note down the exact stop code.
- You can use the Microsoft Support website or a search engine to look up the specific error code and find targeted solutions.
- Use Alternative Antivirus Software Temporarily
To determine if Norton is definitely the culprit, you could temporarily disable Norton’s real-time protection (at your own risk) and launch the game, or temporarily switch to Windows Defender for testing purposes.
- Check System Files and Memory
While SFC /scannow found no issues, the BSOD could indicate a memory problem.
- Run the Windows Memory Diagnostic tool to check your RAM for errors.
By following these steps, you should be able to pinpoint the source of the conflict and prevent future BSODs when launching new games via Steam.
