Just got this one:

Somebody has pinged the system for the "Back Orifice" trojan. Unless the system responds, it is unlikely
that it has been compromised. Back Orifice pings are the most frequent attack seen on the Internet.

Details

Your machine has been scanned, but not targetted. This means the hacker is scanning thousands of machines
on the Interent hoping to find one that has been compromised by Back Orifice. The hacker isn't necessarily
going after you in particular.

Most compromises occur because the hacker posts an infected program or document on the Internet and
hopes that people will run it. The hacker then scans the Internet for these compromised machines.

In other words, while this is a clear sign of an "attack", it isn't necessarily directed against your machine.
Furthermore, even if your machine has been compromised by Back Orifice, the firewall subsystem will
block access to it.
