i have just reinstalled windows xp home & after installing avg pro, spyware doctor & zonealarm pro etc, i have noticed in zonealarm, under firewall zones that there is something called a loopback adaptor.. but when i go to control panel > network connections, that it only says local ara connection.. does anyone know what this loopback adaptor is & if its needed? [bold]i would really appreciate some help, thanks[/bold]
