infection vectors

This describes how the malicious code is automatically transmitted and how the infection occurs. It only applies to self-propagating malicious code (viruses and worms). Each infection vector has an infection rating evaluating the expected contagion rate via the vector. This rating consists of two values: one that rates the inherent effectiveness of the vector in spreading the malicious code, and one that describes how widely deployed the infection vector actually is.
