Verdict Safe
Is Nitro-
None of the 63 antivirus engines that checked it flagged this tiny ZIP archive, although limited prevalence and absent the test run leave modest uncertainty about its contents.
Read the whole reasonShow less
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
Keep protection enabled and use the archive only if it came from an expected source. Rescan and inspect every extracted executable or script before running it.

Why we think so
4 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 63 antivirus engines that checked it flagged the 515-byte ZIP, including all 18 reporting major antivirus engines. The result supports benign handling, but the archive is uncommon and lacks completed sandbox or contacted-host analysis, so inspect its contents before opening anything unexpected.
The strongest evidence is the absence of detections across 76 engines, with no major or independent engine flags. The sample is a very small ZIP archive, so code-signing evidence is not applicable. It is more than a year old but has appeared in only three submissions, which provides limited reputation rather than an active threat signal. No sandbox execution was completed, so behavior in the test run cannot be characterized. Contacted-host reputation was not checked or saved, and two external-intelligence services were skipped, leaving those areas unresolved. Overall, the static evidence contains no hostile indicators.
What We Detected
None of the 63 antivirus engines that checked it flagged the 515-byte ZIP archive. All 18 reporting major antivirus engines were non-detecting, including Microsoft, Kaspersky, ESET-NOD32, BitDefender, and Fortinet, and no engine supplied a malware-family label.
Threat Behavior
No completed sandbox observation is available, so the archive's behavior in the test run, extracted contents, and potential network activity were not observed. A complete contacted-host reputation result is also unavailable. The file is uncommon, with only three submissions over roughly 530 days, but rarity alone does not establish harmful behavior.
What To Do Now
Keep security software enabled and extract the archive only if its source and purpose are expected. Review the extracted filenames before opening them, and rescan any executable or script found inside because archive-level results do not guarantee that every possible inner file was separately assessed.
Where this verdict could be wrong3 caveats
- The archive has been submitted by only three sources, so its real-world reputation is limited despite its age.
- No completed sandbox run is available, and the archive's contents or execution behavior were not observed.
- MalwareBazaar and YARAify checks were skipped, leaving some external-intelligence coverage unavailable.
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 63 antivirus engines that checked it flagged the archive.
- All 18 reporting major antivirus engines were non-detecting.
- No malware-family label, suspicious engine result, or malicious file it created was recorded.
- No filename disguise, brand conflict, or adversarial text pattern was identified.
- The archive has only three recorded submissions, providing limited reputation.
- No completed sandbox run observed the archive's contents or behavior.
- A complete reputation check for any contacted hosts is unavailable.
- Some external-intelligence checks were skipped.
