Using multiple scan engines
FPE gives you the ability to employ up to five scan engines to detect and take action on malware in your organization. Using multiple engines offers increased protection, as malware that gets past one engine is unlikely to get past additional engines. FPE uses scan engines that use both heuristic scanning methods and definitions; the combination helps provide comprehensive malware protection. For a comprehensive discussion of how to use multiple engines to maximize scan-engine performance, see Maximizing scan engine performance.
