Patent Images
1. A method of providing incremental updates to a virus signature database stored in the memory of a mobile wireless platform and used by anti-virus software operating on the mobile wireless platform, the method comprising:
- at a network server, maintaining a server database containing signatures for identified viruses;
when a new virus is identified, adding a signature for that virus to said server database;
generating a Short Message Service or Unstructured Supplementary Services Data message containing said signature, and sending said message to the mobile wireless platform over a cellular radio access network; and
upon receipt of said message at the mobile wireless platform, adding the signature to the virus signature database.

9. A method of protecting a mobile wireless platform against viruses, comprising:
-
maintaining a database of virus signatures on the platform;
updating the database by receiving virus signatures contained in one or more Short Message Service or Unstructured Supplementary Services Data messages sent over a cellular radio access network; and
searching for virus signatures contained in the database.

10. A mobile wireless platform arranged in use to provide anti-virus protection by maintaining a database of virus signatures, receiving over a cellular radio network Short Message Service or Unstructured Supplementary Services Data messages containing virus signatures for newly identified viruses, incrementally updating said database with the received virus signatures, and scanning data held by or received on the platform for viruses matching signatures contained in the database.

11. A method of providing incremental updates to a virus signature database stored in the memory of a mobile wireless platform and used by anti-virus software operating on the mobile wireless platform, the method comprising:
-
at a network server, maintaining a server database containing signatures for identified viruses;
when a new virus is identified, adding a signature for that virus to said server database, and making the signature available at a Multimedia Messaging Service Center;
generating a Multimedia Messaging Service notification containing a link to said signature at said Center, and sending the notification to said mobile wireless platform;
upon receipt of said notification at said mobile wireless platform, establishing a data connection over a cellular radio network, and using said link to download the signature; and
adding the signature to the virus signature database.

12. A mobile wireless platform arranged in use to provide anti-virus protection by maintaining a database of virus signatures, receiving a Multimedia Messaging Service notification containing a link to a storage location for signatures corresponding to newly identified viruses, establishing a data connection over a cellular radio network and using said link to download the virus signature(s), incrementally updating said database with the downloaded virus signature(s), and scanning data held by or received on the platform for viruses matching signatures contained in the database.
