Sustaining a clean system is achieved with other features that also minimize performance impact to servers. In addition, Norton AntiVirus for Microsoft Exchange uses a feature called scan-caching to reduce performance degradation. Also used in Norton AntiVirus for Windows NT Servers and NetWare, Scan-caching tags files when they are scanned, so the next time a scan is run, tagged files are skipped, unless the file has changed. These updates are automatically delivered and fully tested at all times. Norton AntiVirus for Microsoft Exchange is part of Symantec's suite of multi-tier virus protection products designed to protect the enterprise at the desktop, server, groupware servers, Internet, and gateway levels.
