A system, method, and program product is provided that communicates virus information between a computer that detects a virus in a file (the detecting computer system) and the computer that sent the infected file (the infected computer system). When the infected computer system sends an infected file to the detecting computer system the detecting computer system detects the virus in the infected file, retrieves virus information corresponding to the virus (such as the name of the infected file, the identifier, or name, of the virus, the virus definitions used to identify the virus, and any instructions needed to eradicate the virus), and automatically sends the virus information back to the infected computer system over the network.
