clamscan 命令

常用示例

说明

clamscan is a standalone command-line virus scanner from the ClamAV antivirus suite. It scans files and directories for viruses, trojans, malware, and other threats using the ClamAV signature database. Each invocation loads the full virus database into memory, which makes it suitable for one-off scans but slower for repeated use. For high-volume or frequent scanning, the daemon-based clamdscan is preferred as it avoids the database reload overhead. clamscan supports recursive directory scanning, pattern-based file inclusion and exclusion, configurable size limits, and various actions for infected files including removal, quarantine (move), and copying. Scan results can be logged to a file for audit purposes.
