 Virus detection and removal apparatus for computer networks

Abstract

A system for detecting and eliminating viruses on a computer network 
includes a File Transfer Protocol (FTP) proxy server, for controlling the 
transfer of files and a Simple Mail Transfer Protocol (SMTP) proxy server 
for controlling the transfer of mail messages through the system. The FTP 
proxy server and SMTP proxy server run concurrently with the normal 
operation of the system and operate in a manner such that viruses 
transmitted to or from the network in files and messages are detected 
before transfer into or from the system. The FTP proxy server and SMTP 
proxy server scan all incoming and outgoing files and messages, 
respectively before transfer for viruses and then transfer the files and 
messages, only if they do not contain any viruses. A method for processing 
a file before transmission into or from the network includes the steps of: 
receiving the data transfer command and file name; transferring the file 
to a system node; performing virus detection on the file; determining 
whether the file contains any viruses; transferring the file from the 
system to a recipient node if the file does not contain a virus; and 
deleting the file if the file contains a virus.
