Verdict Safe
Is FSDPlugin.
None of the 71 antivirus engines that checked it flagged this decade-old, validly signed Symantec DLL, although PECompact packing and absent observations from the test run…
Read the whole reasonShow less
Strong evidence · A verified publisher signature, and no engine flags it.
Use the DLL if it came from an expected Symantec product or another trusted package. If its origin is uncertain, verify its digital signature and source before allowing an application to load it.

Why we think so
4 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 the DLL, including the major antivirus engines, and its Symantec Corporation signature verifies correctly. It has also circulated since 2016; PECompact packing warrants some caution, but there is no corroborating detection or threat-intelligence hit.
The strongest evidence is complete agreement among the antivirus results: none of the 71 antivirus engines that checked it flagged the DLL, and all 17 major antivirus engines that reported a result were silent. The file carries a verified Symantec Corporation signature dated October 2016. Its long observation history and submissions from 24 sources further reduce concern that it is a newly introduced threat. PECompact packing and high-entropy code make static inspection less transparent, but those properties alone do not establish hostile intent. No observation from the test run or complete contacted-host reputation check is available, so confidence is high rather than absolute.
What We Detected
None of the 71 antivirus engines that checked it flagged FSDPlugin.dll, including all 17 major antivirus engines that reported a result. The DLL has a verified Symantec Corporation signature dated October 2016, and no malware-family label, malware-specific YARA rule, or external sample-feed match was found.
Threat Behavior
No completed sandbox observation is available, so behavior in the test run cannot be characterized. The antivirus analysis shows PECompact packing and high-entropy code; these features obscure code structure but are also used by legitimate commercial software and are not proof of malware.
What To Do Now
The evidence supports normal use when the DLL came from an expected Symantec installation or trusted software package. If its source is unknown or it appeared unexpectedly, verify the signature in Windows and compare the SHA-256 hash with the software vendor's package before loading it.
Where this verdict could be wrong3 caveats
- The DLL is packed with PECompact and has high-entropy code, which reduces static visibility even though packing is not inherently hostile.
- No sandbox execution was completed, so the DLL's behavior in the test run was not observed.
- The signer has no stored historical sample statistics, so the valid signature lacks additional history-based corroboration.
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.
- All 17 reporting major antivirus engines returned no detection.
- The Symantec Corporation code signature verifies correctly.
- The sample has been observed since 2016 across 24 submitting sources.
- No malware-specific research rule or external malware-feed match was found.
- PECompact packing and high-entropy executable code reduce static inspection visibility.
- No completed sandbox run is available to show what the DLL does when loaded.
- No complete reputation check was saved for potential network contacts.
- No historical sample record is available for this signer in the local publisher statistics.

Section entropy & packers
Executable sections have high entropy (7.2+) — the code is compressed or encrypted and only decrypted at runtime. Classic packing behaviour.
Packers compress or encrypt the executable and only unpack it at runtime. Legitimate commercial software uses them too — but if the file is also unsigned and rare, it's a strong malware signal.
How widely this file has been seen
Moderate prevalence — neither rare nor common. No strong prior applies.
