One Windows executable. It scans a file, a folder, or a whole drive when you tell it to, against a signature set — known-bad file hashes plus a set of pattern rules. There is no installer, no background service, and it does not need administrator rights to scan your own files. The signatures come from a plain static path on this site that anyone is free to mirror.
sigil.exe SHA-256: 0dfeee4ea7f7f3fbe9bd5dd5e12952a2766365f4925903c5e0258baf80a89f9c
The exe is not code-signed, so Windows SmartScreen will show a blue "Windows protected your PC" box the first time. Click More info → Run anyway. Verify the SHA-256 above matches your download first.

scan — check a path; it reports each file as clean, suspicious, or infected.update — fetch the latest signatures from this site. The download is verified
against a key built into the binary, so a tampered mirror is rejected.selftest — confirm the build detects its own test set.The signature set is served here as plain static files (manifest.json, a detached
signature, and content-addressed chunks). Any web server, mirror, or CDN can host a copy. Run
sigil update to pull the current set.
