| Description | NETSHIELD is an anti-virus NLM (NetWare Loadable Module) for Novell NetWare/386 Version 3.11. It checks network file servers for both known and unknown viruses. Known virus detection, including stealth and polymorphic (mutation engine) viruses, is done using McAfee Associates' VIRUSCAN virus scanning technology. Unknown virus detection is handled by computing two 16-bit Cyclic Redundancy Checks (CRC) against files and then periodically comparing the file against its CRC for changes. |
