I totaly agree. But AVAST does use Heuristics, although only on its Mail providers. But with the resident shield put up to scan ALL files, no virus will run.

But a good “unpacker engine” is far most important. That’s why I asked many questions (today) in this forum about the options to scan CAB’s also. (microsofts archive)

A heuristic resident scanner, can indeed pull off many fals alert, wich work verry distracting, and could be dangerous, if you delete a “good” file, that is flaged by the heuristic.

Its hard to find a good solution between “strong heuristic” and not many false alerts.
