Why we think so
2 points 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 flagged this file, and 18 major antivirus engines reported it clean. It has been submitted by over 500 users. Its observed network activity is limited to GitHub release lookups for the MelonLoader project, and no injection target was recorded.
No engine flagged the file, including 18 major antivirus engines that reported clean. It is widely submitted, with 515 submitters. The only contacted domain was GitHub, requesting release information for the MelonLoader repositories. The file is unsigned, which limits the positive evidence, but nothing hostile is present.
What We Detected
0 of the 70 antivirus engines that checked it flagged this 64-bit .NET-based installer, and 18 major antivirus engines reported it clean.
Threat Behavior
The sandbox saw it unpack .NET and graphics libraries to temporary folders, create its own settings files, and query GitHub for MelonLoader releases. No injected process was recorded, and the injection and defence-tampering mappings had no supporting artefact.
What To Do Now
No action is needed. As with any download, obtain it from the official MelonLoader project page.
Where this verdict could be wrong2 caveats
- The file is unsigned and 23 days old, and the matching safe verdicts are import-table fingerprint-only collisions, so they add little weight.
- The sandbox mapped and T1562.001, but with no named target or artefact; these are common on clean installers.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No engine out of 75 flagged the file.
- Widely submitted by 515 distinct users.
- Observed network activity is limited to GitHub release lookups for the MelonLoader project.
- The file is unsigned, so the publisher cannot be verified from a signature.
- The file is recent, first seen on Sep 27, 2026.

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.
