Several users have reported similar false positives with Windows Defender and other antivirus software flagging OpenCode binaries
The 'Wacapew.A!ml' detection you're seeing appears to be a false positive, similar to what other users have experienced. These detections are common with bundled executables and development tools.
Feel free to ignore if none of these address your specific case.

As of OpenCode v1.3.4 across the CLI + Desktop apps, we have full code signing - so there should be no more warnings.
Please let me know otherwise
