thank you guys

I did both of the tests.

the GRC was positive except that my PC responded to a PING.
the symantec gave that:
ICMP Ping

Ping. Ping is a network troubleshooting utility. It asks your computer to acknowledge its existence. If your computer responds positively to a ping, hackers are more likely to target your computer.




22

SSH. TCP connections to this port might indicate a search for SSH, which has a few exploitable features. SSH is a secure replacement for Telnet. The most common uses of SSH are to securely login and copy files from a server.




80

HTTP (Hypertext Transfer Protocol). HTTP is used to transfer Web pages over the Internet. Port 80 should be open only if you're running a Web server.



Any idea how I can correct these problems and make these ports stealth?

thanks
