bgolden: I believe you mean the so called “Behavior Blocker” (third page of the Standard Shield configuration window). It should block “suspicious” operations (i.e. operations often used by viruses, but sometimes by ordinary programs as well). It is a feature that was rather useful in the old DOS times, but is a little obsolete today. It’s recommended to keep the default settings, unless you are an experienced user and know exactly what you want.
As already noted, the corresponding help page in the main avast help is:
Resident Protection / Standard Shield Provider Settings / “Blocker” Page.
