Abstract
A system and method for preventing propagation of malicious content associated with an electronic message are disclosed. An electronic message and content associated with the electronic message is simulated in a virtual machine which emulates the destination computing device of the electronic message. A virtual firewall receives one or more commands as the electronic message or content associated with an electronic message is executed. Initially, the virtual firewall establishes a network connection and determines the type of action associated with the commands. If the type of action comprises a connection maintenance or configuration command, the network connection is maintained. If the type of action comprises a data transmission command, the network connection is terminated. This allows the virtual machine to simulate performance of a networked computer by transmitting a subset of the data through a network connection.
