Abstract
A client-based filtering system compares portions of incoming and/or outgoing messages to filtering information in a filter database, and determines whether to block or allow incoming and/or outgoing transmissions of messages in response to the comparison. In response to a match between the portion of the message and the filtering information, the system can employ one of a number of different specified blocking options. The system has an update server that is accessible over the Internet and that has new filtering information for updating the filter database. The filter database can have a filter database stored on a server in a network coupled to the client.
