Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
This program appears safe to run. Obtain it from the project's official download page, since it is unsigned, and keep your antivirus protection enabled.
Good practice2 tips
We found nothing harmful in this file.
Run it only if it came from the developer's own website or an official app store.
Keep your antivirus and Windows updates switched on.

Why we think so
1 point against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 61 antivirus engines that checked it flagged this program, including 12 major antivirus engines that returned clean results. The combined sandbox verdict was clean. The program only wrote its own log file and graphics cache, and contacted no hosts. The file is unsigned, so its origin cannot be confirmed.
None of the 61 antivirus engines that checked it flagged the file, and major antivirus engines such as ESET, Avira, DrWeb and Fortinet reported it clean. The combined sandbox verdict was clean, with no high-risk techniques and no injection into other processes. The program wrote only its own log folder and a Direct3D shader cache, and one dropped file matches a known-software reference entry. No public malware database or community rule matched the hash. The file is unsigned, which limits certainty about who built it.
What We Detected
None of the 61 antivirus engines that checked it flagged this 64-bit Windows program, first seen on Oct 7, 2026, with 92 distinct submitters. Twelve major antivirus engines reported it clean, while a few others timed out. The antivirus analysis found no packer and normal section entropy. The file carries no digital signature.
Threat Behavior
The combined sandbox verdict was clean. The program wrote a log file in its own application folder and a Direct3D shader cache, which fits a graphics application. It contacted no hosts and set no persistence. One dropped file matches a known-software reference entry, and no public malware database matched the hash.
What To Do Now
The file appears safe to use. Because it is unsigned, download it only from the project's official release page, and keep your security software enabled.
Where this verdict could be wrong3 caveats
- The file is unsigned, so nothing confirms who built it.
- Several major antivirus engines, including Kaspersky and BitDefender, timed out and returned no result.
- No complete host-reputation result is available, although the sandbox recorded no network contacts by the sample.
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 61 antivirus engines that checked it flagged the file, including 12 major antivirus engines that returned clean results.
- The combined sandbox verdict was clean with no high-risk techniques.
- The sample contacted no network hosts and created no persistence during sandbox runs.
- One dropped file matches a known-software reference entry.
- No public malware database or malware-specific community rule matched the file.
- The program is not digitally signed, so its publisher cannot be verified.

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.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
