Windows 7: Norton Internet Security NIS 2014. Firewall ports open. Dangerous?

Norton Internet Security NIS 2014. Firewall ports open. Dangerous?

Hi All,

I'm running NIS 20.4.0.40 (latest version) on my fully patched Win7 Pro laptop. I connect to the internet using a 3G cellular modem (Reliance in India). The 3G modem is connected to a Hame external 3G WiFi HotSpot Router (3GWHR). The 3GWHR broadcasts a WiFi signal and that's how my laptop gets internet.

I went to grc.com and did a Shields Up port scan. See attached file to see the detailed results. The port scan shows my Port 23 Telnet and Port 53 DNS are both open. Oh no!

Is this dangerous? How can I fix it? I checked the Firewall control panel and NIS is controlling my firewall, not Windows. Do I need to go into the NIS Firewall settings and manually close these ports?

I'm pretty sure I'm getting a dynamic IP from the ISP. Is my ISP using a NAT and am I behind that NAT?

When I do a full system AV scan with NIS and Malwarebytes free they show no infections.

Do I need to log into my router and change something?

Anyway I can set all the ports to "Stealth"?

Need any other details? Thanks,

Advait

Are you using Telnet to connect to another computer or a Telnet server?

As far as I know I'm not using TelNet. Is there some way to see if some service or other program is using TelNet?
