The reasoning behind this verdict

Analyst conclusion

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.

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.

Is MelonLoader.Installer.dll safe?
We found nothing harmful in MelonLoader.Installer.dll. None of the 70 antivirus engines that checked it flag it. Install it only if it came from the developer's own website or an official app store.
What is MelonLoader.Installer.dll?
MelonLoader.Installer.dll is a software installer, about 23.7 MB. It carries no version information saying what it is or who made it. VirusTotal first saw it on Sep 27, 2026.
How many antivirus engines detected MelonLoader.Installer.dll?
None of the 70 antivirus engines that checked it flag MelonLoader.Installer.dll. That is a good sign, but not proof, so we also weigh who made it, how widely it is used and what it did in a test run.
What is the SHA-256 hash of MelonLoader.Installer.dll?
The SHA-256 fingerprint of MelonLoader.Installer.dll is 45cdf97d0c5161ed2ce844c18214bda006080c760329af1f2efffcfbfe30c961, and its MD5 is 43edd3568190aa0cfa60c6944d3d3b71. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
Is it safe to install MelonLoader.Installer.dll?
We found nothing harmful in MelonLoader.Installer.dll. The main caveat is where you got it: attackers sometimes spread malware under the name of real software, so get it from the official website. If your own antivirus warns about it, check the source before you ignore the warning.
How up to date is this analysis of MelonLoader.Installer.dll?
This report reflects the scan on Oct 9, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
