Quote - I wouldn't worry about it.

I'm not worried about it.  I have no sensitive, classified information on my computer.  I'd just like to know what reason they have for attempting to scan our ports.

I sit behind a router and software firewall most of the time and I've done those port scans to look for open ports and my computer always shows as "stealth". 

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
