orchardcore-antivirus
Skill for scanning uploaded files for malware in Orchard Core 4.0 with the OrchardCore.Antivirus module. Covers the OrchardCore.Antivirus.ClamAV feature (ClamAV Antivirus Scanner), the OrchardCore Antivirus ClamAV configuration section with Host, Port, ConnectTimeoutSeconds and TransferTimeoutSeconds, environment variables, running clamd with Docker, fail-closed behavior, AntivirusScanningException, connection reuse, buffering of non-seekable streams, which uploads are scanned, and clamd StreamMaxLength sizing. Use this skill when requests mention Orchard Core antivirus, ClamAV, clamd, malware scanning, virus scanning of uploads, or closely related Orchard Core setup or troubleshooting work. Strong matches include OrchardCore.Antivirus, OrchardCore.Antivirus.ClamAV, ClamAvOptions, AntivirusScanningException, and clamav/clamav Docker images.

# Orchard Core Antivirus - Prompt Templates
## Scan Uploads with ClamAV
You are an Orchard Core expert. Generate configuration and deployment guidance for scanning uploaded files with ClamAV before Orchard Core stores them.
### Guidelines
- `OrchardCore.Antivirus.ClamAV` (**ClamAV Antivirus Scanner**, Security category) registers a ClamAV `IFileEventHandler` in the shared file upload security pipeline. The pipeline itself (`FileCreationService`, custom upload code, custom handlers) is covered by `orchardcore-file-upload-security`.
- The module ships with Orchard Core 4.0 and is part of `OrchardCore.Application.Cms.Core.Targets`. Only an app that references individual modules needs `<PackageReference Include="OrchardCore.Antivirus" Version="4.*" />` in the web project.
- It fails closed: a malware detection rejects the upload, and a missing `Host`, invalid settings, connection failure, timeout, or unexpected `clamd` response also rejects it.
- Only uploads that go through the pipeline are scanned; see the coverage list below.
- All recipe JSON must be wrapped in the root `{ "steps": [...] }` format.
