Why we think so
1 point against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 62 antivirus engines that checked it flagged this installer, and the combined sandbox verdict over four runs was clean. It made no network contacts and showed no high-risk techniques. It is unsigned, so confirm you downloaded it from the official source.
None of the 62 antivirus engines that checked it flagged the file, including all 18 major antivirus engines that reported on it. The combined sandbox verdict across four runs was clean, and the sandbox recorded only ordinary installer activity such as service creation and system information checks. No public malware database or community rule lists this hash. The package is unsigned and has a modest submission history since first seen on Sep 27, 2026, which leaves its publisher unconfirmed. No completed host-reputation check is available, but the sample made no network contacts in the sandbox.
What We Detected
None of the 62 antivirus engines that checked it flagged this Windows Installer package. That includes major engines such as Kaspersky, ESET, Microsoft and BitDefender. No hit was found in public malware sample databases, community YARA rules or reference databases. The file was first seen on Sep 27, 2026, and about 20 sources have submitted it.
Threat Behavior
Across four sandbox runs, the combined verdict was clean. The installer ran through the standard Windows Installer service, wrote its log and temporary files, and touched system restore settings, which is normal for MSI packages. It made no network connections and showed no high-risk techniques or injection into other processes.
What To Do Now
The package is unsigned, so the evidence does not identify its publisher. Install it only if you obtained it from the developer's official download page, and keep your antivirus protection enabled.
Where this verdict could be wrong1 caveat
- The installer is unsigned, so there is no publisher identity backing it, and it has been shared by only about 20 sources since Sep 27, 2026.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 62 antivirus engines that checked it flagged the file.
- The combined sandbox verdict across four runs was clean, with no high-risk techniques recorded.
- No listing in public malware sample databases or community malware rules.
- The installer made no network connections during sandbox analysis.
- The installer carries no digital signature, so its publisher cannot be confirmed.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
