Firewall??
At last microsoft is promoting a personal firewall day..they are promoting firewall's.Thats strange ahahha.They used to hate them and think that there is no need for a firewall to even exist.Now they are promoting it and even consider to turn on their built-in firewall with the coming of service pack 2 of windows XP...
Firewall is really an essential tool if you want to surf the web.Without firewall you are exposed to danger of the web, virus,worms, exploits and others.
SO boys and girls...get one now.i recommend Zone Alarm.You can get it here
