That's very strange. I can promise you that no external executables, scripts, or installers were added to the build — just the standard Ren’Py runtime and my own game files. It's possible that your antivirus software was unable to read certain executables and flagged the file as a false positive. If you're still skeptical, I recommend using VirusTotal.com to help scan files. It's free to use and can run anything through dozens of antivirus engines.
