Recursive virus detection, protection and disinfecting of nodes in a data network

摘要

Screening and disinfection of a computer network for viral infection by scanning data streams for viruses. When a virus (or worm) is detected at a node, the cure is applied at the node, and detection, protection and cure means are propagated recursively to other nodes which are either potential sources or potential targets of the viral infection. Each infection is thus traced back and forward systematically, curing each node on the infection path.
