Why we think so
3 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
All 70 antivirus engines that checked it returned without a malicious or suspicious detection, including 16 major antivirus engines reporting clean. The DLL has been observed since 2010 and shows no packing or high-entropy code, although it is unsigned and no the test run was completed.
The strongest evidence is complete agreement across 76 antivirus engines, with no malicious or suspicious labels. The file has also been known for more than 16 years, reducing the likelihood that an established malicious sample would remain universally undetected. Static PE analysis found neither packing nor high-entropy code, and no external intelligence source supplied a matching threat indicator. The unsigned status weakens publisher attribution but does not outweigh the broad detection results and long history. No completed sandbox run or complete host-reputation cross-check is available, so activity in the test run remains unverified.
What We Detected
None of the 70 antivirus engines that checked it marked the DLL as malicious or suspicious. The file has been observed since February 2010 across 13 submissions from 12 sources.
Threat Behavior
Static PE analysis found no recognized packer, no likely packing, and no high-entropy code. No rule-based rules fired, no brand mismatch was detected, and YARAify, MalwareBazaar, and CIRCL supplied no corroborating threat hit. No completed sandbox observation or complete contacted-host reputation result is available, so network and behavior in the test run cannot be characterized.
What To Do Now
The evidence supports ordinary use when the DLL came from an expected application or trusted installation source. Keep security software enabled and verify the file's origin if it appeared unexpectedly, because it lacks a digital signature.
Where this verdict could be wrong2 caveats
- The file is unsigned and this signer has no saved history — no authenticated publisher identity or signer history supports the file.
- No completed sandbox run was recorded and no contacted-host reputation result was saved — activity in the test run and contacted-host reputation were not assessed.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/70 antivirus engines reported a malicious or suspicious result.
