Is install.bat safe?
No antivirus engine or external intelligence source identified a threat, although this newly observed PowerShell-related installer lacks runtime and host-reputation coverage.
All 75 antivirus engines returned no malicious or suspicious detection, including 17 tier-1 engines, and no external intelligence source produced a hit. Because the script is newly observed and has no completed runtime analysis or host-reputation check, execute it only if its source and intended actions are trusted.

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 returned no malicious or suspicious detection, including 17 tier-1 engines, and no external intelligence source produced a hit. Because the script is newly observed and has no completed runtime analysis or host-reputation check, execute it only if its source and intended actions are trusted.
Static scanning produced zero malicious or suspicious detections across 75 engines, with all 17 tier-1 participants returning no detection. Research intelligence also supplied no YARAify, MalwareBazaar, or CIRCL hit. These results provide substantial evidence against a currently recognized malware family. However, the file is newly observed, and the PowerShell and URL-related tags indicate capabilities that warrant source verification. No completed runtime observation or complete contacted-host reputation result is available, while the prior file-type-only matches are too broad to establish identity.
What We Detected
The 30,866-byte installer script produced 0/75 malicious detections and 0/75 suspicious detections. All 17 tier-1 engines that participated, including Microsoft, Kaspersky, BitDefender, ESET-NOD32, and Avast, returned no detection. YARAify reported zero matching rules, while MalwareBazaar and CIRCL returned no hit.
Threat Behavior
No completed sandbox run is available, so the script's runtime actions were not observed. The file carries PowerShell and URL-pattern tags, which may reflect scripting or download functionality but do not establish harmful behavior by themselves. No complete host-reputation result is available because contactedHosts was not checked or saved.
What To Do Now
Confirm that the script came from the expected vendor or project and inspect its commands and referenced URLs before running it. Keep endpoint protection enabled, and avoid execution if the source or requested actions cannot be verified.
Where this verdict could be wrong4 caveats
- file.tags includes powershell and url-pattern; scripts that invoke PowerShell or retrieve content can be abused even when static signatures do not trigger.
- behaviour=null means the script was not observed executing, so its commands and any downloaded payloads remain unverified.
- contactedHosts=null means no complete reputation cross-check is available for any URLs or hosts referenced by the script.
- The five similarHashes entries are file-type-only matches to unrelated filenames, so they are weak support rather than close sample matches.
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 engines reported a malicious or suspicious detection
- 17 tier-1 engines returned no detection
- No YARAify, MalwareBazaar, or CIRCL hit
- No confirmed hacktool or test-file label
- No brand mismatch detected
- Newly observed file with only one known submission
- PowerShell and URL-pattern tags indicate script and network-capable content
- No completed runtime observation
- No complete contacted-host reputation result
- No signing identity applies to this script format
Run the script only when it came from a trusted source and its commands and referenced URLs match the expected installation process. Keep endpoint protection enabled.

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
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.
