One signature may contain several virus signatures, which are algorithms or hashes that uniquely identify a specific virus. A large number of viruses may share a single signature, allowing a virus scanner to detect viruses it has never seen before.

Generic or heuristic detection are the two types of scanning that anti-virus software employs when looking for virus signatures. Generic detection is not as effective as heuristic scanning because it neglects to locate new virus signatures, but it is better at finding new viruses that have been developed from existing virus families.
