Nortons is changing my firewall setting or is it something else?

Hey all,

 

I just looked into my "security history" page and noticed whenever I restart my computer (Windows Vista using the lastest version of Nortons) I see a "info" log aboput my firewall.

 

It says "Firewall setting "AlertThreadEnable" changed. It says OLD value 0, NEW value 1. I guess the new value of 1 means on?

 

Why does it do it everytime I restart the computer? Is something trying to turn it off?

 

Thanks,

Marc
