Why we think so
4 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The two generic detections are outweighed by 267 independent submitters, silence from major antivirus engines, and a clean combined sandbox verdict across four runs. The executable is unsigned and protected, so it should still be obtained from the project’s established release channel and scanned before installation.
Two of the 67 antivirus engines that checked it flagged the installer, but neither detection names a malware family and no major antivirus engines agreed. The file has been submitted by 267 sources, providing a substantial benign anchor despite being first seen on Oct 2, 2026. The combined sandbox verdict was clean, with no named injection target, persistence indicator, malicious child, or high-risk technique recorded. Reputation checks covered every observed contact and found no current malicious or suspicious host; the one historical record was stale and adds no weight. The executable is unsigned and protected with .NET Reactor, which warrants caution, but those properties do not overcome the stronger benign evidence.
What We Detected
DeepInstinct and Trapmine flagged the installer, accounting for 2 of the 67 antivirus engines that checked it. Their labels are generic, no major antivirus engines detected malware, and no engine consensus identified a real family. The file has also been submitted by 267 distinct sources.
Threat Behavior
The combined sandbox verdict was clean. The installer created temporary setup files and launched the installed application, but no named process-injection target, persistence mechanism, malicious child, or high-risk technique was recorded. Reputation checks covered all observed contacts and found no current malicious or suspicious host.
What To Do Now
Prefer the project’s established release channel and verify that the download source and version match what you intended to install. Keep security software enabled and rescan the installer before running it, particularly because it is unsigned and uses code protection.
Where this verdict could be wrong3 caveats
- The Windows executable is unsigned and protected with .NET Reactor, reducing publisher assurance and making its code harder to inspect.
- DeepInstinct and Trapmine flagged the file, although neither supplied a named malware family and no major antivirus engines agreed.
- One behaviour rule associated packing and a network request with a possible downloader profile, but the evidence from the test run did not show a downloaded stage or other high-risk technique.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 2 of the 67 antivirus engines that checked it flagged the file, and no major antivirus engines detected it.
- The file was submitted by 267 distinct sources a total of 293 times.
- The combined sandbox verdict was clean without a named injection target or persistence mechanism.
- All observed contacts received reputation coverage, with no current malicious or suspicious host found.
- The only child with a saved reference verdict was present in a known-software reference set.
- The executable is unsigned, so there is no verified publisher identity attached to these bytes.
- Two engines raised generic alerts.
- The executable uses .NET Reactor protection, which makes code inspection more difficult.
- One behaviour rule associated the combination of protection and a network request with possible downloader activity, although no downloaded payload was observed.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
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.
EvidenceT1055 (sandbox MITRE mapping)Unsigned, packed PE with sandbox-observed network activity. The packing step hides the payload until execution; the network call fetches / reports for the next stage. Classic dropper / stager behaviour.

Section entropy & packers
A known packer signature (UPX / Themida / VMProtect / etc.) matched this file. Packers aren't malicious on their own, but most malware uses them.
Packers compress or encrypt the executable and only unpack it at runtime. Legitimate commercial software uses them too — but if the file is also unsigned and rare, it's a strong malware signal.
How widely this file has been seen
Lots of people are uploading this but it's recent — typical of newly-released legitimate software. Low prior for malware.
