I have an issue with my network. Every day my Public IP address is blacklisted in CBL (www.abuseat.org) and i have to manually remove it and i’m been warned that i will be permanently blocked if something is not done about it. The description is that someone on my inside network is visiting a conficker sinkhole over port 80. Is there anyway i can block all related conficker sinkhole traffic or get a log to identify the Ip address generating such traffic. Thanks
