I've been using ZA for many years. Not had this problem before:
Essentially the AV and APhish updates seem to hang for 15-30 minutes either at 0% or, more often, at 100% and the CPU (I've only got one core, don't laugh) is sometimes nearly at 100%. After logging on the whole PC is obviously dead slow until the update is done.
My specs are:
ZoneAlarm Security Suite version:9.3.014.000
Anti-virus engine version:220.127.116.11
Anti-virus signature DAT file version:1032930912
ZoneAlarm Browser Security 18.104.22.168
ZoneAlarm ForceField Spyware Scanner 22.214.171.124
ZoneAlarm ForceField Anti-Phishing Database 126.96.36.199
ZoneAlarm ForceField Spyware Sites Database 04.130
PC has XP (AMD 3200+) with the all service patches.
