hi! This is Crespo calling.Need some advice re: Firewalls. I have just the basic one that comes with Windows XP.I would like to instal a more powerful one such as the free ZoneAlarm & i also intend to download the new WindowsOneCare programme which has a new Firewall in it as well.My question is can i install these two extra Firewalls or(like anti-virus) can i only have one running on my lap-top? Totally new to these extra security measures - in fact new to everything! As always, any help from anyone will be v.v. appreciated. Cheers! C.
