ClamXav
ClamXav is a free and paid antivirus scanner for macOS that uses the popular open-source ClamAV engine to detect and remove viruses, malware, adware and ransomware targeting both Mac and Windows systems. Users can run on-demand scans of files, folders or the entire disk, set up scheduled scans, use real-time monitoring via the Sentry feature to quarantine threats as they arrive, and update malware definitions automatically. It is widely used by individual Mac users and small organisations seeking a lightweight alternative to commercial antivirus suites.

1 suggestionClamXav ships with native Apple Silicon support — the current installer at clamxav.com explicitly lists "Either an Apple Silicon processor (eg M1, M2 etc) or Intel processor" in its system requirements, and the vendor's download page offers version 3.10 and later builds that run natively on M-series Macs. If you are still running an older Intel-only build of ClamXav, simply visit clamxav.com/download, download the latest installer (version 3.10 or later), and run it. The installer will automatically detect your Mac's processor and install the appropriate native build. Your existing quarantine history and scan settings will be preserved. After installation, you will see better performance and battery efficiency compared to running the old Intel version under Rosetta.
