Is SecurityTest_Batch.bat safe?
No antivirus engine detected this tiny batch file, although its recent appearance and lack of runtime analysis warrant ordinary caution before execution.
All 75 antivirus engines avoided flagging the 190-byte batch file, including 17 tier-1 products, and no known-malware intelligence matched it. Confidence is moderated because it was submitted only once, no sandbox run completed, and the contacted-host reputation check is unavailable.

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.
All 75 antivirus engines avoided flagging the 190-byte batch file, including 17 tier-1 products, and no known-malware intelligence matched it. Confidence is moderated because it was submitted only once, no sandbox run completed, and the contacted-host reputation check is unavailable.
Static antivirus results provide the strongest evidence: 0 of 75 engines flagged the sample, with no tier-1 detection or family consensus. MalwareBazaar and CIRCL produced no match, while YARAify coverage was unavailable due to a timeout. The file is only 190 bytes, but batch scripts can still execute consequential commands and no runtime observation is available. Its filename-related security-software heuristic is informational and is unsupported by any detection. The four prior file-type-only results offer weak supporting context because they concern unrelated formats rather than close code or publisher matches.
What We Detected
None of 75 antivirus engines flagged the 190-byte DOS batch file. Seventeen tier-1 engines, including Avast, BitDefender, ESET-NOD32, Kaspersky, and Microsoft, reported no detection, and there is no identified threat family.
Threat Behavior
No completed sandbox observation is available, so the script's runtime actions were not observed. The contacted-host reputation cross-check was also not completed or saved. MalwareBazaar and CIRCL returned no matches, while YARAify timed out and therefore provides no result.
What To Do Now
Keep endpoint protection enabled and run the file only if it came from an expected source. Because batch files can execute system commands, inspect its short text contents or test it in an isolated environment if its origin is uncertain.
Where this verdict could be wrong3 caveats
- prevalence.classification=rare_new records only one source and one submission, so the file has no established reputation.
- behaviour=null means execution was not observed, and contactedHosts=null means no complete host-reputation result is available.
- externalIntel.availability.yaraify='error' leaves a researcher-rule coverage gap.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 antivirus engines flagged the sample
- tier1Malicious=0 and 17 tier-1 engines reported no detection
- No MalwareBazaar or CIRCL match
- No malicious child or confirmed hacktool evidence was reported
- No brand mismatch or adversarial-text contamination was detected
- Newly observed file with only one recorded submission
- No completed sandbox execution
- No complete contacted-host reputation result
- YARAify rule check timed out
- Batch scripts can execute system commands without requiring an executable signature
Keep endpoint protection enabled and verify the file's source before running it. If unexpected, inspect the 190-byte script as text or execute it only in an isolated test environment.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Run it only when it came from the developer's official site or another source you independently trust.
- Recovery step 02
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
- Recovery step 03
Keep your antivirus and Windows updates switched on so you stay protected.
