ClamWin

General Overview

ClamWin is a bare-bones antivirus scanner for Windows, built around the open-source ClamAV engine. There’s no real-time protection, no fancy dashboards, no background monitoring. It does one thing: scans files or directories for known threats using an up-to-date signature database.

This tool is mostly used by advanced users who either want a secondary scanner to run on-demand or need something minimal for low-resource systems. It’s also handy in air-gapped environments where cloud-based AVs are off the table.

ClamWin integrates into Windows Explorer’s right-click menu and can be run via command line, which makes it scriptable for batch jobs or offline maintenance.
