Network Shield Does Not Install

Avast Free Antivirus / Premium Security
1

I installed Avast! 4.5 Home Version using Typical
installation, uninstalled, and reinstalled using
Custom (checking Network Shield).
In both cases, the Network Shield does not appear
as a resident scanner.

I’m running Avast! 4.5 Home Version on my old
Win98 laptop.
I downloaded the installer Feb 02, 2005.
The version number is 4.5-561.

(I also have Zonealarm firewall installed.)

ANY IDEAS WHY NETWORK SHIELD DOES NOT INSTALL?
