vlflt.sys Functionality:

The vlflt.sys file is identified as a kernel-mode driver associated with Bitdefender's security suite. Specifically, it functions as a Virtual File System Filter driver. This component plays a critical role in Bitdefender's real-time protection mechanism by intercepting and analyzing file system operations. This interception allows the software to scan files for potential malware or threats before they are executed, thereby providing proactive security.

Error 0xC000007B Context:

The error code 0xC000007B, indicating "STATUS_INVALID_IMAGE_FORMAT," is a common issue that typically arises from conflicts or inconsistencies in the application's dependencies. This error signifies that the application is attempting to load an incompatible or corrupted DLL (Dynamic Link Library) file.

Potential Causes and Resolution Strategies:

Based on common causes, the following troubleshooting steps are recommended to address the 0xC000007B error:

1. Microsoft Visual C++ Redistributable Issues:
   • Cause: Missing or corrupted Microsoft Visual C++ Redistributable packages, which are essential runtime components for many applications.
   • Resolution:
     • Download and reinstall the latest versions of all Microsoft Visual C++ Redistributable packages from the official Microsoft website. Ensure compatibility with your system architecture (x86 or x64).
     • If recent updates were performed, it can be useful to uninstall all current C++ redistributables, and then perform a fresh install.
2. .NET Framework Problems:
   • Cause: Corrupted or missing .NET Framework installations.
   • Resolution:
     • Repair or reinstall the appropriate .NET Framework version(s) required by the affected application. Download the installer from the official Microsoft website.
     • Use the .NET Framework Repair Tool provided by Microsoft.
3. DirectX Incompatibilities:
   • Cause: Outdated, corrupted, or incompatible DirectX components.
   • Resolution:
     • Update DirectX to the latest version using the DirectX End-User Runtime Web Installer from the Microsoft website.
4. System File Corruption:
   • Cause: Corrupted system files that may impact application dependencies.
   • Resolution:
     • Execute the following commands in an elevated Command Prompt (Run as Administrator):
       • sfc /scannow: This command scans and repairs corrupted system files.
       • DISM /Online /Cleanup-Image /RestoreHealth: This command repairs the Windows system image and requires a working internet connection to replace corrupted files on the system via Windows Update.
     • Restart the computer after the commands have completed.

Considerations Regarding vlflt.sys:

While vlflt.sys is a component of Bitdefender, the 0xC000007B error is generally not directly caused by the driver itself. However, conflicts arising from corrupted system files or incompatible dependencies could potentially affect the functionality of the driver or related applications.

@camarie, correct me if I am wrong and provide any possible workarounds.

True, but vlflt.sys, being a driver, uses and loads components of kernel mode, so the redistributables, .NET, DirectX etc. do not apply. Rather I would investigate some form of update malfunction, for example a 64-bit driver on a 32-bit OS, that would be a cause for 0xC70000007B, or the driver file got somehow corrupted.
On the other hand, such a driver would not load, although I don't know if Windows will not BSOD even if the driver could not be loaded due to a wrong bitness file. If that would have been a filesystem driver, it would make sense to bluescreen since that would be a critical OS component, but a filter driver, it is not loadable, I think it would not load, record an error, and continue.

But I am no expert in drivers installation, so I would let someone else who knows 100% about this subject.

@dvsls, can you provide some insights here.
