We've got something pesky on our SBS2008 server with exchange. Pesky as in no virus or malware solution can identify the cause. Our firewall is now blocking many outgoing port requests created by this bug and I just put Malwarebytes on it to see what it can tell me. Looking at my log file it keeps getting a few hits from a overseas IP that is questionable. I don't understand what this telling me as it's coming through port 25 which has to go through our firewall too which should be finding this before the server. Please just explain to me what this data is telling us. The screenshot talks about one item trying to out and several trying to get in. Thanks for your help.
