Is build.bat safe?
New Dyalog file with zero engine detections but insufficient coverage for a confident verdict.
All 75 engines returned clean results and no external intelligence sources flagged the file. However, the file is only hours old, has a single submission, and no sandbox or host-reputation data is available.

Before running
Treat the file as unverified and avoid running it until more evidence is available.
If you already ran it
Run a full device scan. If its origin cannot be confirmed, delete this file and use a fresh copy from a trusted source.
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 75 engines returned clean results and no external intelligence sources flagged the file. However, the file is only hours old, has a single submission, and no sandbox or host-reputation data is available.
Zero malicious detections across 75 engines, including 17 tier-1 engines, is a strong clean signal. The file type is uncommon and the sample is brand new, so historical context is absent. Similar files matched only on filetype also received unknown verdicts due to low coverage. No sandbox execution data, dropped children, or contacted-host reputation results exist to corroborate safety. The combination of clean engine results and missing runtime evidence leaves the sample in the unknown category.
What We Detected
75 antivirus engines scanned the 1.5 KB Dyalog file and none flagged it as malicious or suspicious. No tier-1 engine raised an alert.
Threat Behavior
No sandbox execution data is available, so runtime behaviour cannot be assessed. The file has not been observed contacting any network hosts, and no child processes or dropped files were recorded.
What To Do Now
Because coverage is low and the file is newly submitted, treat it with caution until more samples or sandbox results appear. Keep endpoint protection enabled and avoid executing untrusted scripts.

How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.

What to do now
There isn't enough information to give this file a clear rating.
- Recovery step 01
Be cautious — an unknown rating is not the same as a clean bill of health.
- Recovery step 02
Run it only when it came from the developer's official site or another source you independently trust.
- Recovery step 03
When in doubt, don't run it — or scan it again later once it's more widely seen.
