Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
No action is needed for this file. If you are replacing a Windows component, use copies from official Windows sources rather than third-party downloads.

Why we think so
2 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Its structure contains only data and resource sections, with no code, consistent with a visual-style resource library. Three sandbox runs showed no injection, persistence or network contact, and the combined verdict was clean.
The DLL contains only a read-only data section and a large resource section, with no code section and no packing, so it carries little capacity to act on its own. Three sandbox runs loaded it and recorded only the loader processes. They saw no injection, persistence, dropped files or network contacts, and the combined sandbox verdict was clean. The file is unsigned and was first seen on Oct 17, 2026 from a single submitter, which leaves no publisher history behind it, but no external database or rule matched it either.
What We Detected
None of the 71 antivirus engines that checked it flagged this 64-bit DLL. The file was first seen on Oct 17, 2026 and has been submitted by one source. It is unsigned and was built with Microsoft Visual C++. Its layout is resource-only: a small data section plus about 141 KB of resources, with no executable code section and no packing.
Threat Behavior
Three sandbox runs loaded the DLL through the standard Windows loader. They recorded no high-risk techniques, no process injection, no persistence, no dropped files and no network contacts, and the combined sandbox verdict was clean. No malware-database listings or malware-specific rules matched the file.
What To Do Now
No action is needed. As with any system-style file, prefer copies obtained from official Windows installation or update sources.
Where this verdict could be wrong2 caveats
- The file is unsigned and was submitted by a single source, so no publisher history backs it.
- The sandbox tagged debug-environment detection and long sleeps. These tags most likely come from the loader harness, because the DLL contains no code section of its own.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 71 antivirus engines that checked it flagged the file, including all major antivirus engines.
- The DLL contains only data and resource sections, with no executable code.
- Three sandbox runs showed no injection, persistence, dropped files or network activity.
- There are no matches in public malware databases or malware-specific rules.
- The file is unsigned, so no publisher identity backs it.
- It is rarely submitted, with a single source since its first-seen date.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
These identify the compiler, runtime or installer used to build the file. They are not packing and are not a risk signal on their own.
How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.
