Hi, Encountered an embedded graphic on a page today, it is from danasoft.com
(http://www.danasoft.com/vipersig.jpg) where it lists my

IP
ISP
System
Browsers

I have a Zone-alarm free firewall installed when these info appeared

I'm confused... Does these appear by default to others in online? Are these info. supposed to be hidden? How does having a firewall help?

Appreciate your help. Thank you
