The reasoning behind this verdict

Analyst conclusion

None of the 70 antivirus engines that checked it flagged this DLL, and it carries a valid Microsoft Corporation signature. It has been seen from thousands of independent sources over several years. One sandbox run returned a malicious label while another returned clean, but no hostile runtime artefact was recorded.

Where this verdict could be wrong1 caveat
  • One sandbox run labelled the file as evasive malicious, but another run returned clean. No injection target or other hard runtime artefact was recorded, so the split result is consistent with a library loaded out of context.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Questions & answers

Short answers to the 7 questions people ask most about this file.

Is d3dcompiler_47.dll safe?
We found nothing harmful in d3dcompiler_47.dll. None of the 70 antivirus engines that checked it flag it. It has a valid digital signature from Microsoft Corporation. Use it only as part of a program you got from the developer's own website.
What is d3dcompiler_47.dll?
d3dcompiler_47.dll is a Windows library (DLL), about 4.5 MB. Its version information says it is “Direct3D HLSL Compiler for Redistribution” (Microsoft® Windows® Operating System). The digital signature from Microsoft Corporation checks out. VirusTotal first saw it on Mar 20, 2020.
How many antivirus engines detected d3dcompiler_47.dll?
None of the 70 antivirus engines that checked it flag d3dcompiler_47.dll. That is a good sign, but not proof, so we also weigh who made it, how widely it is used and what it did in a test run.
Is d3dcompiler_47.dll digitally signed?
Yes. d3dcompiler_47.dll has a valid digital signature from Microsoft Corporation, which shows the file hasn't been changed since that publisher signed it. Malware is sometimes signed with stolen certificates, so a signature alone isn't proof of safety.
What is the SHA-256 hash of d3dcompiler_47.dll?
The SHA-256 fingerprint of d3dcompiler_47.dll is 44422e6936dc72b7ac5ed16bb8bcae164b7554513e52efb66a3e942cec328a47, and its MD5 is 7641e39b7da4077084d2afe7c31032e0. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
Is it safe to use d3dcompiler_47.dll?
We found nothing harmful in d3dcompiler_47.dll, and its digital signature checks out. The main caveat is where you got it: attackers sometimes spread malware under the name of real software, so get it from the official website. If your own antivirus warns about it, check the source before you ignore the warning.
How up to date is this analysis of d3dcompiler_47.dll?
This report reflects the scan on Oct 18, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
