ZA starts when my computer starts up. At some point ZA shuts off by itself and windows firewal turns on. Why is this happening.

I am running XP
ZoneAlarm Security Suite version:9.1.008.000
TrueVector version:9.1.008.000
Driver version:9.1.008.000
Anti-virus engine version:8.0.2.42
Anti-virus signature DAT file version:998021216
AntiSpam version:6.0.0.2383

Thank you.
Dave
