I installed Norton Personal Firewall on my computer on
the 27th. Since then I have had numerous attempts from
outside TCP addresses to unload backdoor trojan horse
viruses on my computer.

Aside from simply having the firewall, is there a means
of reporting this information?

Not only to catch individuals who send the virus, but
protect those who transmit such information unaware?
