Is D3D11.dll safe?
This file is a legitimate component of the DXVK graphics translation layer, and the single engine detection is a documented false positive common to this open-source project.
Our analysis indicates this file is a legitimate DXVK DLL, a common open-source graphics translation tool. The single detection by ClamAV is a known false positive, and no other security engines or sandbox behaviors suggest malicious activity.

Before using
Use it only as part of software obtained from the developer's official site or another source you independently trust.
If you already used it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Our analysis indicates this file is a legitimate DXVK DLL, a common open-source graphics translation tool. The single detection by ClamAV is a known false positive, and no other security engines or sandbox behaviors suggest malicious activity.
The file is a component of the DXVK project, which is widely used for graphics translation. The single detection by ClamAV is a documented false positive for this project. The sandbox behavior, while triggering a process injection heuristic, is consistent with the expected operation of a DLL wrapper that hooks into graphics APIs. No other engines, including all high-trust tier-1 engines, identified any threat, and there is no evidence of malicious network activity or malicious dropped files.
What We Detected
The file 'D3D11.dll' was flagged by a single engine (ClamAV) as 'Win.Trojan.Virut-53'. However, our analysis of the broader engine network shows that 74 out of 75 engines, including all 17 high-trust tier-1 engines, found the file to be clean. This pattern is characteristic of a false positive.
Threat Behavior
The sandbox analysis triggered a heuristic alert for process injection (MITRE T1055). This is expected behavior for a DLL wrapper like DXVK, which must hook into graphics APIs to translate Direct3D calls to Vulkan. There was no evidence of malicious network connections, dropped malicious children, or other indicators of compromise.
What To Do Now
This file is a legitimate component of the DXVK project. If you are using this file as part of a game or application, it is safe to use. Ensure you have downloaded it from a trusted source, such as the official project repository.
Where this verdict could be wrong1 caveat
- The file is unsigned, which prevents verification of its origin, though this is common for community-maintained open-source projects.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 74/75 engines clean
- All tier-1 engines clean
- Documented false positive
- No malicious network activity
- Unsigned file
The file is safe to use as it is a legitimate component of the DXVK project. Ensure you obtain it from the official project source.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
