Open Source Antivirus
Malware detection is an arms race where the scanner is only as good as the signatures and heuristics behind it, and a closed engine asks you to trust both without ever seeing how a verdict was reached. The open source tools here let you inspect the detection logic and write your own rules, so you can tune what gets flagged and keep scanned files inside your own environment.
