I just had to reinstall Avast because the service would not start. Repair did nothing. Is there any way to save the custom settings so you don’t have to do them all over again on a reinstall?
Looks like I’ve found the answer. The settings on my PC (XP) are in the ini files located at:
C:\Documents and Settings\All Users\Application Data\Alwil Software\Avast5
Avast5.ini holds most of the settings - the other inis are self-explanatory.
