Is ProjectZomboid_PublicTechDemo_0_1_4c_plusbatchfix.zip safe?
Only Webroot flagged this long-established archive with a generic trojan label, while tier-1 engines, sandbox conclusions, and external intelligence provided no corroboration.
Webroot was the only one of 75 engines to flag the archive, using a generic trojan label; no tier-1 engine agreed. Its long history and broad submission footprint strongly favor a false positive, although several behavior mappings and inconclusive extracted-file checks warrant routine caution.

Before opening or extracting
Open or extract it only when its sender or download source has been independently verified.
If you already opened or extracted it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Webroot was the only one of 75 engines to flag the archive, using a generic trojan label; no tier-1 engine agreed. Its long history and broad submission footprint strongly favor a false positive, although several behavior mappings and inconclusive extracted-file checks warrant routine caution.
One of 75 engines flagged the archive, and that detection came from Webroot with the generic label W32.Trojan.Gen. No tier-1 engine detected it, while 14 tier-1 engines explicitly reported no detection. The file has circulated since 2012 across 130 sources and 153 submissions, which supports established software rather than a newly distributed threat. One completed sandbox run produced no malicious conclusion or persistence indicators, though it mapped activity to T1485, T1486, and T1562.001. External intelligence supplied no matching malware records or YARA rules, but the extracted children remain inconclusive and no complete host-reputation result is available.
What We Detected
Only Webroot flagged the archive among 75 engines, assigning the generic label W32.Trojan.Gen. No tier-1 engine detected it, and there is no family consensus. The archive has also been observed since 2012, with 130 sources and 153 submissions.
Threat Behavior
One completed sandbox run recorded Java and game-library activity, including temporary DLL execution through rundll32. It produced no malicious sandbox conclusion or persistence indicators. The mappings T1485, T1486, and T1562.001 are counter-signals, but they lack supporting detections or a malicious child; all ten extracted-child results remain inconclusive. No complete host-reputation cross-check is available.
What To Do Now
Use a copy obtained from an official or otherwise trusted archive, verify its SHA-256 value, and keep endpoint protection enabled. Avoid the file if its origin is uncertain or if its contents differ from the expected historical demo package.
Where this verdict could be wrong3 caveats
- behaviour.offensiveTechniques lists T1485, T1486, and T1562.001, which can represent destructive or defense-evasion activity, despite the lack of a malicious sandbox conclusion.
- droppedChildren inspected ten extracted files, but droppedChildren.rollup.unknown=10 means none received a conclusive child verdict.
- contactedHosts=null, so no complete host-reputation cross-check is available.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No tier-1 engine detected the file.
- Only 1/75 engines flagged it, and the sole detector is low-trust.
- Observed since 2012 across 130 sources and 153 submissions.
- No malicious sandbox conclusion or persistence indicators.
- No MalwareBazaar, CIRCL, or YARAify hit.
- Webroot reports W32.Trojan.Gen.
- Sandbox mappings include T1485, T1486, and T1562.001.
- All ten extracted-child verdicts are inconclusive.
- No complete contacted-host reputation result is available.
Prefer a copy from an official or trusted historical source and verify SHA-256 2d2274cf2d6ced5b772b74dafa2bef8eb4e30fabc3ea1dcfbde80a53980da39d. Keep endpoint protection enabled during extraction and use.
