ANTI-VIRUS SIGNATURE FOOTPRINT

摘要

A computer anti-virus system is disclosed. The computer anti-virus system can have multiple detection layers and can include a first memory and a second memory. The computer anti-virus system can have a reduced first memory size requirement for a fingerprint signature based anti-virus application program by putting off to the second memory those signatures that are redundantly detected on other layers. Thus, performance can be enhanced and/or costs can be reduced.
