1. A method of managing a virus signature database associated with an anti-virus application, both of which are resident in a memory of a mobile wireless computer device, the method comprising:
- receiving management messages over the wireless interface, the management messages containing respective add, delete, or replace virus signature instructions for adding, deleting and replacing individual signature entries of the virus signature database to maintain the effectiveness of the database;
wherein the method further comprises filtering the management messages either at the origin side of the wireless interface, prior to transmission over the wireless interface, or following receipt at a mobile device, to allow only messages relevant to a particular device or software installed on that device to be sent to that device or to be acted upon at the device.

Abstract
A method of managing a virus signature database associated with an anti-virus application, both of which are resident in a memory of a mobile wireless device 2,4. Management messages containing for example new virus signatures are sent from the network 1 to the device 2,4. In accordance with instructions contained in the management messages, individual signature entries of the virus signature database are deleted or replaced, and new signatures added.

6. A mobile wireless computer device having a memory and an anti-virus software application resident in the memory, the memory also containing an anti-virus signature database accessible in use by the anti-virus application, the device comprising:
-
a receiver for receiving management messages over a wireless interface, the management messages containing respective add, delete, or replace virus signature instructions for adding, deleting and replacing individual signature entries of the virus signature database to maintain the effectiveness of the database; filtering means for filtering the management messages to allow only messages relevant to the device or software installed on the device to be acted upon at the device; and processing means for adding, deleting, or replacing individual signature entries of the virus signature database.

11. A method of scanning information for the presence of a virus, the method comprising extracting predetermined virus signatures from a virus signature database and sequentially searching for the presence of signatures in the information, wherein the database contains for each of one or more viruses a plurality of signatures, and indicating the presence or absence of each of said one or more viruses based on a combination of the results of the plurality of searches.
