About:
ClamAV is an open-source anti-virus engine designed for detecting trojans, viruses, malware, and other malicious threats. It is widely used on mail servers as a scanning backend for email attachments. The software provides a command-line scanner and a scalable, multi-threaded daemon for on-demand or continuous file system scanning.
Key Features:
  • Multi-threaded daemon (clamd) for high-performance scanning
  • Signature-based detection with daily virus definition updates
  • Support for scanning archives (ZIP, RAR, TAR) and executables
  • Integration capabilities for mail servers and file gateways
Use Cases:
  • Scanning email attachments on mail servers (e.g., Postfix, Exim)
  • On-demand file system scanning for malware detection
  • Automated file integrity checks in DevOps pipelines
Alternatives:
  • ClamAV Desktop – GUI wrappers for ClamAV offering real-time protection on macOS/Windows
  • Sophos – Commercial endpoint protection with broader features but requires a license
