A digital message pre-filtering system that is able to identify a digital message that is not capable of carrying an unwanted or undesirable component prior to full scanning of the message, for example, by filtering software wherein if the message is determined not to be capable of carrying an unwanted or undesirable component then it is not passed onwards to be fully scanned and if the message is capable of carrying undesirable or unwanted component then it is forwarded to be fully scanned. The method can be seen in sending a message from a sender 10 to a recipient 20 wherein the message is pre-filtered 12 using a virus pre-filter, spain pre-filter 13 and content pre-filter 14 and is only passed to be fully scanned 15 (virus filter), 16 (spam filter), 17 (content filter) if the message may contain undesirable content. Otherwise the message is output to the recipient 20 without being fully scanned. The pre-filtering may be used in a message filtering system which comprises a database module containing one or more configuration options relating to one or more end-users and a scanning engine module connected to the database module. The system may also include a message archiving system and a message prioritization system also connected to the database module. The behavior of the scanning engine module, the message archiving system and the message prioritization system are modified on a message-by-message basis according to the configuration options for the end-users. The digital message may be IM (instant messaging) for text and image messaging computer to computer, SMS (short message service) for text messaging via mobile devices, VOIP (Voice over IP) for communication via telephony, MMS (Multimedia messaging) for transmission of images, 3GP for transmission of video, and fax. In further aspects, the message filtering system may additionally include a set-up process so that a third party database may be synchronized as appropriate with the database module.
