Patent Images
1. A computer program product embodied on a non-transitory computer readable medium, comprising:
- computer code to receive network traffic through an input port, where the network traffic is segmented into predetermined portion types and the content of the network traffic is associated with a file being transferred from a source device to a destination device,computer code to determine identifying information regarding the file;
computer code to employ the identifying information to consult a file reputation database over a network;
computer code to receive a message based upon the consultation with the file reputation database;
computer code to prevent passage to the destination device of a last portion of network traffic until the message is received, andcomputer code to conditionally forward the last portion of the network traffic associated with the file transfer if the message does not indicate that the file is unwanted;
wherein the last portion of network traffic comprises a positive integer quantity of the predetermined portion types.

Abstract
A system, method, and computer program product are provided for preventing communication of unwanted network traffic by holding only a last portion of the network traffic. In use, network traffic associated with a file transfer is received. Additionally, only a last portion of the network traffic associated with the file transfer is held for determining whether the file is unwanted. Further, the last portion of the network traffic associated with the file transfer is conditionally forwarded to a destination device, based on the determination.
