What it does
ClamWin is an open-source Windows virus scanner using the ClamAV engine, with scheduled and manually triggered scanning.
ClamWin provides a Windows interface around a ClamAV-based scanning workflow. Its official page lists a scheduler, database updates and Explorer right-click integration. That can suit deliberate scans of a folder or file collection. The same page explicitly says it has no on-access real-time scanner. Plan its role as a manual or scheduled scanner rather than expecting every file open to trigger a check. That constraint is central when deciding how it complements the computer's other security controls.
