How to use it well

ClamAV is a useful option for administrators adding malware scans to file and mail workflows. Update signatures and scan a representative test directory before integrating the engine into a mail or upload pipeline. Start with a small, representative task so you can check the results before extending the setup.

Define how findings are reviewed and quarantined, and monitor update failures rather than assuming the scanner stays current. Consider the practical trade-off: detection depends on signatures and configuration.
