Is umpdc.dll safe?
Only Symantec flagged this unsigned, newly observed DLL, while 16 other tier-1 engines found nothing; missing runtime evidence prevents stronger reassurance.
Symantec alone flagged the DLL with a generic machine-learning label, while 74 of 75 engines did not and 16 tier-1 engines reported no detection. The file is unsigned, newly observed, and lacks sandbox evidence, so the isolated alert is likely a false positive but remains unresolved.

Before using
Do not use it until the source and publisher can be verified independently.
If you already used it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Reinstall the parent software from the developer's official site instead of replacing this component by itself.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Symantec alone flagged the DLL with a generic machine-learning label, while 74 of 75 engines did not and 16 tier-1 engines reported no detection. The file is unsigned, newly observed, and lacks sandbox evidence, so the isolated alert is likely a false positive but remains unresolved.
The scan produced one detection among 75 engines, and Symantec supplied only a generic machine-learning label rather than a recognized malware family. Sixteen other tier-1 engines, including Kaspersky, BitDefender, ESET-NOD32, Avast, and Fortinet, reported no detection. Static PE data shows neither packing nor high-entropy code, and external intelligence produced no corroborating match. However, this is an unsigned DLL seen from only one source, which weakens provenance and makes the isolated tier-1 alert worth retaining as a concern. No completed sandbox observation or complete contacted-host reputation check is available, so behavior cannot be assessed. Overall, the evidence leans toward a false positive but does not support treating the file as established benign software yet.
What We Detected
Symantec was the only engine among 75 to flag the DLL, reporting the generic label ML.Attribute.HighConfidence. Sixteen other tier-1 engines, including Kaspersky, BitDefender, ESET-NOD32, Avast, and Fortinet, reported no detection, and there is no multi-engine family consensus.
Threat Behavior
No completed sandbox observation is available, so runtime activity cannot be characterized. A complete reputation check of contacted hosts is also unavailable. Static PE analysis found no identified packer, no likely packing, and no high-entropy code; researcher intelligence returned no corroborating YARA, CIRCL, or known-malware match.
What To Do Now
Keep endpoint protection enabled and avoid loading the DLL unless its origin and purpose can be verified. If it came with legitimate software, obtain a fresh copy from the vendor's official release channel and rescan it after additional engine updates or sandbox analysis become available.
Where this verdict could be wrong4 caveats
- Symantec is a tier-1 engine and reported 'ML.Attribute.HighConfidence', so its lone detection cannot be dismissed as low-trust noise.
- The DLL is unsigned and has only 1 submission from 1 source, leaving little provenance or prevalence support.
- No completed sandbox run is available, so potentially harmful behavior could remain unobserved.
- No YARAify, CIRCL, or MalwareBazaar hit was found, but absence of those matches does not establish benignity.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 74/75 engines did not flag the sample
- 16 tier-1 engines reported no detection
- No strong tier-1 family consensus
- peAnalysis.likelyPacked=false and peAnalysis.highEntropyCode=false
- externalIntel.yaraify.ruleCount=0 and externalIntel.circl.hit=false
- Symantec tier-1 detection: ML.Attribute.HighConfidence

Do not load the DLL until its source is verified; keep endpoint protection enabled and obtain a replacement from the official vendor channel if applicable. Reassess when runtime analysis or broader detection history becomes available.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Barely seen in the wild and first surfaced recently. 1 antivirus detection make that low prevalence materially relevant, but rarity alone is not proof of malware.

- Recovery step 01
Don't use it unless you're certain it came from a source you trust.
- Recovery step 02
Check where you got it — an unexpected attachment or a random download link is a red flag.
- Recovery step 03
Do not delete or replace the component manually. Quarantine it with your antivirus or repair the parent software from its official source. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
