Hm, I suspect it has to do with how the bulletin board system communicates with the client. I'd like to see the actual log information (src_host, dst_host, src_port, dst_port, timestamp). Anti-virus programs have a terrible problem with false positives.
I checked over your server and couldn't find any signs of compromise or malicious activity. It looks completely clean.
