Why we think so
0 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 65 antivirus engines that checked it flagged this ZIP archive, including every major antivirus engine. It was first seen in 2015 and has been submitted by 61 different sources, and it matches no malware database or malware-specific rule. No the test run is available, so this assessment rests on static and engine evidence.
The file has a long, stable history: first seen in 2015 and submitted by 61 distinct sources without picking up detections. Malware sample databases and community rule sets returned no matches. Code signing does not apply to ZIP archives, so its absence is neutral. No sandbox run or contacted-host check is available, so behaviour in the test run of the contents was not observed.
What We Detected
None of the 65 antivirus engines that checked it flagged this ZIP archive, and all 18 major antivirus engines that analysed it reported it clean. It matched no malware sample database entries and no malware-specific rules, and none of our behaviour rules matched.
Threat Behavior
No the test run is available for this archive, so the behaviour of the files inside it was not observed. The static evidence is consistent with an ordinary archive: it has circulated since 2015 and been submitted by 61 different sources without gaining detections.
What To Do Now
The archive appears safe to use. As with any download, obtain it from a source you trust, keep your antivirus enabled, and let it scan the extracted files before running any program inside.
Where this verdict could be wrong1 caveat
- No sandbox run is available for this archive, so the behaviour of the files inside it was not observed when it ran.
