Why we think so
0 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 this installer, and it carries a valid signature from Now.gg, INC, the company behind BlueStacks. Thousands of distinct users have submitted the same file, and the sandbox runs showed ordinary installer activity, contacting only BlueStacks' own cloud service.
None of the 71 antivirus engines that checked it flagged the file, including all 18 major antivirus engines that returned a result. The signature from Now.gg, INC verified, and every earlier sample we have seen from this signer was clean. Nearly 2,800 distinct users submitted this exact file within 11 days, which fits a popular emulator installer. The four sandbox runs recorded no high-risk techniques with supporting artefacts and no injected processes, and the only network contact was BlueStacks' own country-lookup service, which our host reputation check found clean. Previous files sharing this build and signer were all judged clean.
What We Detected
None of the 71 antivirus engines that checked it flagged this BlueStacks installer. It carries a valid code signature from Now.gg, INC, and the same file has been submitted by about 2,800 distinct users. No public malware database or community rule set lists it.
Threat Behavior
Across four sandbox runs the installer unpacked its interface assets into a temporary folder and contacted BlueStacks' own cloud service to look up the user's country. Our reputation check of both contacted hosts found nothing malicious or suspicious. Some generic technique labels appeared in the sandbox summary, but no target process or matching artefact was recorded, which is typical of ordinary installers.
What To Do Now
If you downloaded this from the official BlueStacks website, it is reasonable to install it. Keep your antivirus enabled during installation, as usual.
Where this verdict could be wrong1 caveat
- The signer is not yet on our curated trusted-publisher list and has a short history of four samples, so publisher trust rests partly on prevalence and clean detections.
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 file
- Valid code signature from Now.gg, INC, with a clean history for this signer
- Submitted by about 2,800 distinct users, consistent with widely used software
- Network activity limited to BlueStacks' own service, which our reputation check found clean
- Earlier files from the same signer and build were all judged clean

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.
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.
