Verdict Safe
Is Polar
None of the 70 antivirus engines that checked it flagged this installer. Sandbox activity showed no high-risk techniques, though its signature fails verification.
Read the whole reasonShow less
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
Install only if you obtained this file from the developer's official source, and keep your security software 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.

Why we think so
1 point against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 70 antivirus engines that checked it flag this installer, and the sandbox runs recorded no injection into other processes, no malicious verdict and no network contacts. It carries a signature that fails chain verification, so its publisher cannot be confirmed. Download it only from the developer's official site.
None of the 70 antivirus engines that checked it flagged the file, and all 18 major antivirus engines reported it clean. The sandbox runs recorded only techniques common in legitimate software. No process injection target, no malicious verdict and no network contacts were observed. The executable is not packed, and its code sections show ordinary entropy. The main caveat is a signature that fails chain verification, which leaves the publisher unconfirmed. No complete host-reputation result is available, but no hostile evidence was found.
What We Detected
None of the 70 antivirus engines that checked it flagged this installer, including every major antivirus engine. The file carries a signature that fails chain verification, so its publisher cannot be confirmed. It is not packed.
Threat Behavior
The sandbox runs saw the installer relaunch itself with install and load arguments. It wrote ordinary files and created standard graphics program markers. No injection into other processes was recorded, no network contacts were made, and no run returned a malicious verdict. The sandbox also mapped some techniques that commonly appear on clean installers, but none was observed doing what those labels describe.
What To Do Now
Use the file only if it came from the developer's official download page. Keep your antivirus enabled during installation, and rescan if a newer build is offered.
Where this verdict could be wrong2 caveats
- The embedded signature fails chain verification, so the author of this installer cannot be confirmed.
- The file has a modest submitter base (6 sources), and the contacted-host reputation check was not completed.
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 70 antivirus engines that checked it flagged the file, including all major antivirus engines.
- The sandbox runs showed no injection, no malicious verdict and no network contacts.
- The executable is not packed or obfuscated.
- The digital signature fails chain verification, so the 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.

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.
