Is setup.bat safe?
Zero engine detections, common-old prevalence, and clean sandbox behaviour outweigh a single generic encoded-PowerShell heuristic.
74 engines report no malicious detections and the file shows common-old prevalence across thousands of submissions. Sandbox analysis found no malicious verdicts or malicious host contacts despite one offensive MITRE technique. The encoded-PowerShell heuristic is a generic pattern also used by legitimate installers.

Before running
Run it only when it came from the developer's official site or another source you independently trust.
If you already ran 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.
74 engines report no malicious detections and the file shows common-old prevalence across thousands of submissions. Sandbox analysis found no malicious verdicts or malicious host contacts despite one offensive MITRE technique. The encoded-PowerShell heuristic is a generic pattern also used by legitimate installers.
The complete absence of malicious detections across 74 engines, including 17 tier-1 engines, is the strongest signal. Widespread distribution (common_old) and clean sandbox behaviour further support a benign classification. The single triggered heuristic reflects a common installer pattern rather than confirmed malice. Community comments suggesting suspicion rely on heuristic tags without engine consensus. No external intelligence sources flag the sample.
What We Detected
Zero malicious detections from 74 engines; 17 tier-1 engines returned clean. Sandbox execution showed typical installer behaviour with one offensive MITRE technique (T1059.001) but no malicious verdicts or host contacts.
Threat Behavior
The file uses encoded PowerShell, a technique common to both legitimate installers and malware loaders. No dropped malicious children, no contacted malicious hosts, and no external intelligence hits.
What To Do Now
Treat as a standard PowerShell-based installer. Verify the source before execution and monitor for unexpected network activity.
Where this verdict could be wrong2 caveats
- FileScan.IO community comments (5 entries) label the file SUSPICIOUS with 100/100 confidence, but these rely on heuristic tags (findstr, lolbin, schtasks) without tier-1 engine corroboration.
- behaviour.offensiveTechniques includes T1059.001 (PowerShell), which can indicate malicious loaders, yet the same technique is common in legitimate administrative scripts.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 engines malicious
- common_old prevalence (3649 sources)
- no malicious sandbox verdict
- no external intelligence hits
- Encoded PowerShell usage (generic loader pattern)
The file can be considered safe for execution from a trusted source; continue standard security hygiene.
