Verdict Safe
Is Party
No engines flagged this established Microsoft-signed DLL, and the isolated mapping lacks a target or corroborating malicious behavior.

Why we think so
2 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 71 antivirus engines that checked it flagged PartyWin.dll, and its signature verifies to Microsoft Corporation, a curated trusted publisher. One sandbox mapped possible process injection, but named no injected target, returned no malicious outcome, and provided no corroborating network or persistence evidence.
The strongest evidence is the verified Microsoft Corporation signature combined with no detections among 75 engines. The file has also circulated broadly since 2021, with 622 submitters and 985 submissions, reducing concern that it is a newly introduced impersonation. Five recent signer-matched files received consistent benign assessments, and Microsoft signer history is 28 of 29 in that direction. A sandbox mapped T1055, but no injected target was recorded and the run did not produce a malicious outcome. Ten dropped files remain unresolved, and no complete host-reputation cross-check is available, but those coverage limits do not outweigh the strong identity, prevalence, and detection evidence.
What We Detected
None of the 71 antivirus engines that checked it flagged the DLL, including all 17 major contributors. Its digital signature verifies to Microsoft Corporation and matches a curated trusted publisher, while historical signer data records 28 of 29 assessed samples as benign. The file has been observed since 2021 across 622 submitters and 985 submissions.
Threat Behavior
One completed sandbox run mapped T1055, which can indicate process injection. However, it recorded no injected target, no malicious sandbox outcome, no persistence indicators, and no sample network contacts. The ten dropped files have no saved assessments, so their status remains unresolved; no complete contacted-host reputation result is available.
What To Do Now
Use the file only when it came from Microsoft, Windows, or another trusted software package, and retain security software. If its origin is unexpected, verify the digital signature and hash before loading the DLL.
Where this verdict could be wrong3 caveats
- One sandbox mapped possible process injection under T1055, although it identified neither an injected process nor a malicious sandbox outcome.
- Ten dropped files have no saved assessments, leaving their status unresolved rather than established as benign.
- No complete contacted-host reputation result is available, although the observed sandbox run recorded no sample 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.
- No antivirus engine among 75 flagged the file.
- The digital signature verifies to Microsoft Corporation, a curated trusted publisher.
- The Microsoft signer history contains 28 benign assessments out of 29 samples.
- The file is established, with 622 submitters and 985 submissions since 2021.
- Five recent signer-matched files received consistent benign assessments.
- One sandbox mapped possible process injection behavior, but did not identify a target process.
- A complete reputation check for contacted hosts was not available.
