The reasoning behind this verdict

Analyst conclusion

This is a small 64-bit Windows API-set stub library with a verified Microsoft signature. None of the 70 antivirus engines that checked it flagged it, and it has been seen by 584 sources since 2018. It also appears in a reference database of known software files.

Where this verdict could be wrong2 caveats
  • One community annotation reports a third-party 'likely malicious' result, but that comment field was flagged as untrusted, and another sandbox annotation plus our own sandbox run reported clean.
  • Our host-reputation cross-check was not completed, so we have no complete reputation result for any network contacts.

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 apisetstub safe?
We found nothing harmful in apisetstub. 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 apisetstub?
apisetstub is a Windows library (DLL), about 18.7 kB. It carries no version information saying what it is or who made it. VirusTotal first saw it on May 12, 2018.
How many antivirus engines detected apisetstub?
None of the 70 antivirus engines that checked it flag apisetstub. 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 apisetstub digitally signed?
Yes. apisetstub 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 apisetstub?
The SHA-256 fingerprint of apisetstub is 55574f9e80d313048c245acefd21801d0d6c908a8a5049b4c46253efaf420f89, and its MD5 is 9476affaac53e6e34405c4001f141805. 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 apisetstub?
We found nothing harmful in apisetstub, 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 apisetstub?
This report reflects the scan on Oct 16, 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.
