Computer virus protection

摘要

A network is protected from e-mail viruses through the use of a sacrificial server. Any executable programs or other suspicious parts of incoming e-mail messages are forwarded to a sacrificial server, where they are converted to non-executable format such as Adobe Acrobat PDF and sent to the recipient. The sacrificial server is then checked for virus activity. After the execution is completed, the sacrificial server is rebooted.

1. A method comprising:
receiving, at a computing device, a message containing an attachment comprising an executable code; comparing, by the computing device, a type of the attachment to one or more lists of attachment types; if the type of the attachment is not in the one or more lists, converting, by the computing device, the executable code from an executable format to a non-executable format, such that the executable code is rendered inoperable, using an application-level process that retains semantic content of the message; and forwarding the attachment containing the non-executable format from the computing device to a target recipient of the message.
