Abstract:

A computer system and method for intercepting, examining, and controlling data streams flowing via transport connections between the transport layer of an operating system and the user application; which operates on a single computer. The system and method preferably operates with a single computer system. All data streams that pass from an external network, through the transport layer of an operating system to the user application or from the user application to the transport layer are intercepted by a network traffic interceptor. The network traffic interceptor processes all data streams for proscribed data that may include viruses, trojan horses, worms, and other hostile algorithms. The processing used by the network traffic interceptor can include monitoring, blocking or destroying data, thereby protecting the single computer system from being infected by hostile algorithms.
