Public IP blocked

I have had my public IP blocked due to the following:

"This IP address is infected with, or is NATting for a machine infected with a Trojan called Win32/Zbot (Microsoft), also known as “ZeuS” or “WSNPoem”.

I need help to do the following suggestion on my firewall:

“To find an infected computer on a NATted network you will have to search through your firewall logs for packets/connections going to 192.42.119.41 destination port 80. However, any process or host sending/receiving large numbers of UDP or TCP packets on high ports (10,000 and higher) should be looked at closely.”

I would appreciate some help in tracking this infected computer/s on my network.

Thank you

Hennie.

You must provide your router credentials (read-only) for that
