KNOW ABOUT FIREWALLS

What is a Firewall?

A firewall is a piece of software or hardware that creates a protective barrier between your computer and potentially damaging content on the Internet. It helps guard your computer against malicious users and many computer viruses and worms.Firewalls help safeguard your computer by enforcing restrictions on incoming traffic. Firewalls can also help mask your computer's identity, so hackers' attempts to probe or scan your computer cannot return
the type of information that makes it easy to invade.

IF YOUR ISP GIVES U A STATIC IP ADDRESS........

More risk if you use broadband [DSL or a cable modem] A dial-up connections uses a different
IP address every time it connects to the Web so it is a moving target. Static IP is not provided
for Dial-Up users. Hackers don't target the Dial-Up users due to this reason. DSL or cable connections use a network address [IP Address] that doesn't change. A firewall helps obscure your network address, even though it always stays the same.ICF helps protect the system from Worms and Messenger Service ADs Virus Alert About the Blaster Worm and Its Variants: http://support.microsoft.com/?kbid=826955
