ClamAV vs Norton 360

ClamAV is a free, open-source antivirus engine for email and web scanning and endpoint security tasks. It provides a multi-threaded daemon, a command-line scanner and a tool for automated virus database updates. The database receives updates multiple times per day, and the updater supports scripted updates and digital signatures. ClamAV scans standard mail formats and many archive, executable and document formats, including MS Office, HTML, RTF and PDF. A Milter interface supports Sendmail. On modern Linux versions, ClamOnAcc can scan files when accessed, with an option to block access until scanning finishes. Signed signature databases limit execution to trusted definitions. The project lists GNU/Linux, FreeBSD, macOS and Windows as regularly tested platforms, and official Docker images are available for Alpine Linux and Debian Linux. ClamAV is an engine and associated tools, not a traditional antivirus or endpoint security suite. Recommended minimum resources are 3 GiB RAM, a 2.0 GHz CPU and 5 GiB of free disk space. The project does not guarantee extraction of every version or variant of supported formats.
