Description
Anti-virus software is the most commonly used technical control for malware threat mitigation. Real-time scanning of files as they are read from disk is a crucial first line of defense from malware attacks but to ensure all files are frequently scanned, a regularly scheduled full scan will ensure malware missed by the real-time scanning will be detected and mitigated.
