Anti-Virus Implementation for Beginners: A simple guide to implement an Anti-Virus program

In the antivirus world, a signature is an algorithm that uniquely identifies a specific virus. Depending on the type of scanner being used, it may be a static hash which, in its simplest form, is a calculated value of a snippet of code unique to the virus. A single signature may be consistent among a large number of viruses. This allows the scanner to detect a brand new virus it has never even seen before. This ability is commonly referred to as either heuristics or generic detection. The Book concentrates on creating a simple Anti-Virus Program based on signatures. Its unique algorithm uses a simple hashing algorithm to calculate hashes and detect viruses.
