Open Ports

Hi

 

  I have installed NIS 2010 on my pc. I checked my security status through symantec security check :

 

  http://security.symantec.com/sscv6/home.asp?langid=ie&venid=sym&plfid=24&pkj=MHFVHGKEWRQCVTYHPMX

 

  The security check  reports three ports are open :

 

 

  1- " ICMP 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 ."

 

  2-"  Telnet. Telnet can be used to log into your computer from a terminal anywhere in the world. This port should be open only if you're running a Telnet server."

 

  3- " 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."

 

 

  Is it normal?  should I reconfigure windows security or NIS?

 

 

Thanks
