Code: This IP is infected (or NATting for a computer that is infected) with the cutwail spambot. In other words, it's participating in a botnet. If you simply remove the listing without ensuring that the infection is removed (or the NAT secured), it will probably relist again. My server IP is blacklisted with cbl.abuseat.org How I can remove this infection from server? Please help. No Idea from where and how to find it.
