Attempting connection to your computer. . .
Shields UP! is now attempting to contact the Hidden Internet Server within your PC. It is likely that no one has told you that your own personal computer may now be functioning as an Internet Server with neither your knowledge nor your permission. And that it may be serving up all or many of your personal files for reading, writing, modification and even deletion by anyone, anywhere, on the Internet!
Your Internet port 139 does not appear to exist!
One or more ports on this system are operating in FULL STEALTH MODE! Standard Internet behavior requires port connection attempts to be answered with a success or refusal response. Therefore, only an attempt to connect to a nonexistent computer results in no response of either kind. But YOUR computer has DELIBERATELY CHOSEN NOT TO RESPOND (that’s very cool!) which represents advanced computer and port stealthing capabilities. A machine configured in this fashion is well hardened to Internet NetBIOS attack and intrusion.
Unable to connect with NetBIOS to your computer.
All attempts to get any information from your computer have FAILED. (This is very uncommon for a Windows networking-based PC.) Relative to vulnerabilities from Windows networking, this computer appears to be VERY SECURE since it is NOT exposing ANY of its internal NetBIOS networking protocol over the Internet.

è grave?cosa devo fare?

Quando ho fatto il test la prima volta ho avuto come risultato questo:

ALL tested ports were STEALTH,
NO unsolicited packets were received,
NO Ping reply (ICMP Echo) was received.

Utilizzavo il firewall freeware (Il merito è principalmente suo) offerto da Comodo. Ho riprovato a far il test ora con Norton360 e Shields UP! non riesce ad effettuarlo:

“Your Internet port 139 does not appear to exist! [...] But YOUR computer has DELIBERATELY CHOSEN NOT TO RESPOND (That’s very cool!) which represents advanced computer and port stealthing capabilities”

ALL tested ports were STEALTH,

Without your knowledge or explicit permission, the Windows networking technology which connects your computer to the Internet may be offering some or all of your computer’s data to the entire world at this very moment!
