A heuristic (pronounced hyu-RIS-tik and from the Greek "heuriskein" meaning "to discover") is a "rule-of-thumb." Heuristics software looks for known sources, commonly-used text phrases, and transmission or content patterns that experience has shown to be associated with e-mail containing viruses. Because many companies or users receive a large volume of e-mail and because legitimate e-mail may also fall into the pattern, heuristics software sometimes results in many "false positives," discouraging its use. Security experts note that, although such software needs to get better, it is a valuable and necessary tool.
