recently I start using ZoneAlarm Free Firewall.
At this point it seems nice, but I have encountered one issue.

Every time when I start my computer (Windows 7 64 bits),
the ZoneAlarm Free Firewall installation window will always pop up, downloading and installing new updates. Afterwards, the firewall start up and everything seems working fine.

At first I thought there is really many new updates for the firewall.
However, I have tried to restart my computer for around 20 times last night,
for every start up, the same installation window pops up, downloading and installing new updates.

I am using the firewall with the latest avast! anti-virus free edition.

Could anyone help me on it?
Thanks a lot.
