First Claim
Patent Images
1. A method of detecting viruses in a computer network, the method comprising:
- intercepting data at at least one data transit node of the network;
identifying at the transit node which of the data is of a type capable of containing a virus;
transferring the identified data to a virus scanning server over the network; and
receiving the identified data at the virus scanning server and scanning the data to identify viruses present therein.

Abstract
A method of detecting viruses in a computer network 1 comprising intercepting data at at least one data transit node 4 of the network 1. The transit node 4 identifies which of the data is of a type capable of containing a virus and transfers the identified data to a virus scanning server 7 over the network 1. The identified data is received at the virus scanning server 7 which scans the data to identify viruses present therein. The server 7 subsequently acts in dependence upon the outcome of the virus scan.

10. Apparatus for detecting viruses in a computer network, the apparatus comprising:
-
a first computer providing a transit node for data being transferred within the network or destined for the network, the computer having means for intercepting said data and for identifying data which is of a type capable of containing a virus; and
a second computer coupled to said network and having processing means for scanning data for viruses, the first computer additionally having means for transferring any identified data to the second computer over said network for virus scanning. - View Dependent Claims (11)

12. A computer memory encoded with executable instructions representing a computer program for causing a computer connected to a data network to:
-
receive data over the data network from a transit node, said data having been intercepted by the transit node and identified thereat as being of a type capable of containing a virus; and
scan the received data to identify viruses present therein.
