Block Ping Requests

I ran a Shields Are Up test at www.grc.com and got the following result:

Your system REPLIED to our Ping (ICMP Echo) requests, making it visible on the Internet. Most personal firewalls can be configured to block, drop, and ignore such ping requests in order to better hide systems from hackers. This is highly recommended since "Ping" is among the oldest and most common methods used to locate systems prior to further exploitation.

Does anyone know what I have to do to block/ignore/drop these requests, and is it desirable to do so?

Re: Block Ping Requests

1) Norton Smart Firewall default blocks ICMP echo.

2) Your router hides your PC from the internet.

3) If you're behind a router, it is the router that is responding, not Norton.

Your router is what Shields Up! actually sees, rather than the Norton Smart Firewall.  When you are behind a router your computer does not face the internet and is invisible to the outside world, so the software firewall cannot really be tested using these types of port scanners. (credit SOJ)

Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an ICMP echo reply. It measures the round-trip time from transmission to reception, reporting errors and packet loss.
