Abstract
A virus detection mechanism is described in which virus detection is provided by a network integrated protection (NIP) adapter. The NIP adapter checks incoming media data prior to it being activated by a computing device. The NIP adapter operates independently of a host processor to receive information packets from a network. This attribute of independence allows NIP anti-virus (AV) techniques to be “always on” scanning incoming messages and data transfers. By being independent of but closely coupled to the host processor, complex detection techniques, such as using check summing or pattern matching, can be efficiently implemented on the NIP adapter without involving central processor resources and time consuming mass storage accesses. The NIP adapter may be further enhanced with a unique fading memory (FM) facility to allow for a flexible and economical implementation of polymorphic virus detection.
