Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 74 engines returned clean results on this 1912-day-old EPUB file. No sandbox, dropped-child or host-reputation data exists, but the file's age and prevalence indicate a legitimate e-book.
Zero malicious detections across 74 engines, including 17 tier-1 engines, eliminates any engine-based threat signal. The file has been submitted 227 times by 206 sources since 2021 and carries only ebook-related tags. External-intel sources (CIRCL, MalwareBazaar, YARAify) report no matches. No sandbox or network data is present, but the absence of any positive malicious indicators supports a clean classification.
What We Detected
74 antivirus engines scanned the file; none flagged it malicious or suspicious. External threat-intel databases returned no matches.
Threat Behavior
No sandbox execution data, dropped children or contacted-host reputation results are available. The file shows only ebook-related metadata and tags.
What To Do Now
The file can be opened with any standard EPUB reader. Keep endpoint protection enabled as a general precaution.
Where this verdict could be wrong1 caveat
- contactedHosts is null so no host-reputation cross-check is available; absence is neutral and does not confirm clean network behaviour.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Zero detections from 74 engines
- Long history (1912 days) with 206 unique submitters
- No external-intel hits
Open the EPUB with any standard reader; no further security action required.

What to do now
This file appears low risk based on the evidence available now.
Open it only when its sender or download source is one you independently trust.
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
Keep your antivirus and Windows updates switched on so you stay protected.
