Per esempio ho tentativi da:
TCP port 445 from 218.71.17.173 TCP port 3080 TCP flags S
TCP port 445 from 219.140.129.194 TCP port 31419 TCP flags S

Ecco cosa dice Zone Alarm:
ZoneAlarm blocked access to port 445 on your computer
No breach in your security has occurred.
Your computer is safe.

What happened?
ZoneAlarm prevented a remote computer from connecting to port 445
on your computer. If you are sharing files on a local network,
this connection attempt was probably legitimate network traffic.
Port 445 is commonly used by networked Windows computers to
display network directories. However, if the traffic that
generated this alert came from the Internet rather than a
local network, this may have been attack on your computer

Should I be concerned?
No. ZoneAlarm blocked the connection attempt, so no harm can
come to your computer from it. However, blocking traffic on
this port can keep you from seeing shared resources on
your local network. Also, Windows file sharing can represent
a security vulnerability if you do not password-protect
your shared files.

Che ne dite ?
