What do when ISP address found after Trojan attack? 1

[dpcjudy]

My firewall reported a trojan attack and the ISP address for the attacker.

I went to "WhoIS" and found the name associated with the ISP address.

Sorry to be so dumb, but what do I do now?

Call the offender?

Thanks for any help...

It might not be a trojan attack, people tend to scan whole subnet's for infected hosts then use them, if the attack was just once off then i would just leave it. Its not worth the hassle but it the a repeat attack happening then you email the isp at abuse@ISPaddress.
