Why we think so
4 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 71 antivirus engines that checked it flagged the installer, including all 17 major antivirus engines that returned results. Its verified Now.gg signature, three signer-matched favorable predecessors, and clean sandbox verdict strongly support legitimate installer activity, although ten extracted files remain unclassified.
None of the 71 antivirus engines that checked it flagged the executable, and the 17 major antivirus engines that returned results reported no detection. The signature verifies to Now.gg, whose limited recorded history contains three favorable samples and no malicious ones. Three earlier files sharing both the import-table fingerprint and signer were also assessed favorably, which makes a generic installer-framework collision less likely. and were mapped during analysis, but those mappings lack corroboration from engines, malware-specific research rules, malicious files it created, or the sandbox verdict. Ten extracted files remain unclassified, and a complete reputation cross-check for contacted hosts was not available.
What We Detected
None of the 71 antivirus engines that checked it flagged the executable. All 17 major antivirus engines that returned results reported no detection, and no engine supplied a malware-family label.
The executable carries a verified signature from Now.gg. The available publisher history is small but favorable: three prior samples were assessed positively and none were malicious. Three closely related BlueStacksInstaller.exe files with the same import-table fingerprint and matching signer also received favorable assessments.
Threat Behavior
One completed sandbox run returned a clean verdict. It observed installer extraction activity without sample network contacts, persistence indicators, registry changes, or injected processes. The analysis mapped T1485 and T1486, which warrant attention because they are associated with destructive behavior, but no concrete destructive outcome or independent malware signal corroborated those mappings.
The installer extracted ten files it created, but no saved assessments are available for them. They therefore remain unclassified rather than confirmed benign. A complete contacted-host reputation result is also unavailable, though the observed run recorded no sample network contacts.
What To Do Now
Use the installer only if it came from the expected official distribution channel and Windows still reports a valid Now.gg signature. Keep security software enabled, and rescan if the signature changes, the installer requests unusual security changes, or unexpected behavior appears.
Where this verdict could be wrong3 caveats
- The runtime mapping included and T1486, techniques associated with destructive activity, but the observed execution did not produce a malicious sandbox verdict or supporting detections.
- The publisher history contains only three prior samples, so the verified Now.gg signature has less historical support than an established auto-trusted signer.
- Ten extracted files remain unclassified, and no complete contacted-host reputation check is available.
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 71 antivirus engines that checked it flagged the executable.
- The file has a verified digital signature from Now.gg.
- All three recorded samples from this signer received favorable assessments.
- Three closely related, signer-matched installers received favorable prior assessments.
- The completed sandbox run returned a clean verdict and observed no sample network contacts, persistence, or process injection.
- The sandbox mapped two techniques associated with destructive activity, although no destructive outcome was corroborated.
- The publisher history covers only three earlier samples and has not reached established auto-trust status.
- Ten extracted files it created do not yet have saved assessments.
- No complete host-reputation cross-check is available.
