no firewall?

I booted up m computer earlier, and there was an icon on my taskbar that said there was no firewall detected... But there was one when I turned off the computer... My anti-virus is still working though

if you know you have a firewall then ignore it. If you need a firewall, then sygate personal firewall (available from www.oldversion.com) is a very good free firewall for windows xp.

yeah, I already have a firewall... I restarted the computer and it came back, so problem's solved
