ABSTRACT:
In one embodiment, an add-on pre-scanner card is removably pluggable into a local bus of a computer. The add-on pre-scanner card may be coupled to a computer network to receive network traffic. The add-on pre-scanner card may be configured to extract payloads from received packets and scan the payloads for computer viruses. The add-on pre-scanner card may pass scanned payloads and other data to the computer by way of a shared memory interface. The pre-scanner card may identify each payload as infected with a virus, virus-free, or unknown to allow the computer to distinguish payloads that do not need further scanning from those that do. The computer may further scan for viruses payloads that the pre-scanner card cannot ascertain as either virus free or virus infected.
