Expected Behavior

The windows installer shouldn't be flagged as a trojan

Current Behavior

Windows Defender currently flags the "*-windows-x64-Installer.exe" as a Trojan:Win32/OffLoader!MTB and promptly deletes the file.

Steps to Reproduce

  1. Create a release using tags
  2. Download the created "*-windows-x64-Installer.exe"
  3. Scan with windows defender ...

Anything else we should know?

This wasn't happening before I merged with latest. https://github.com/EZ64cool/obs-hadowplay/issues/9

Our working theory is that this is due to lots of malware using an almost-default InnoSetup configuration (much like we do for the plugin template) and as such generated installers run afoul of heuristics checks.

There is really not much we can do about that (except for developers to report false positives for their installers to Microsoft, though that's admittedly quite annoying).

If somebody wants to replace InnoSetup with NSIS (in the hopes that it generates less false positives) we'd probably be open to review/merge it.
