Sigil

an on-demand malware scanner

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.

First run on Windows

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.

Signatures

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.

Sigil is beta software provided as is, with no warranty of any kind, express or implied.
You use it at your own risk. Free to use for personal home use.
