"""S-28 (#191): prove clamd is up, has signatures loaded, and scans a stream over INSTREAM.
|
|
|
|
The EICAR test file must come back FOUND and a clean payload OK — the same protocol the domain's
|
|
scanner adapter will speak (ADR-0036). EICAR is assembled from two halves so this file itself is
|
|
not flagged by an on-access scanner on a developer laptop. Stdlib only (python:3-slim).
