The product version of the exe I have is 1.0.0.1 - I think the exe version I quoted - 4.0.172 - may have been the newer number after the update.
My comp froze after getting to the desktop and attempting to load items in the system tray; didn’t seem like Explorer got to load, since nothing else worked at all. Sometimes the avast! icon in the tray would have a red circle with a diagonal line through it.
