How tight is your firewall?

You can check it out by clicking here

Scroll done the page to PROCEED, then chose a service to scan your PC for vunerable ports.

Try common ports and service ports.

I'm happy to say mine is all locked up tight. (Using Norton)

Mines tighter than a fishes bottom in the deep blue sea:D

Heres mine.

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

Well I am behind a hardware firewall

I have used some before but this one is good, explains it is simple terms

Your system has achieved a perfect "TruStealth" rating
