Upon logging into my OpenDNS dashboard, I got this happy message:
Malware/Botnet Activity Detected Activity Label IP Last seen Malware Home 184.108.40.206 Sep 9, 2012, 12:06am MDT
Here are the stats:

From what I gather, this indicates that I visited a website at some point this morning that had been infected with a script of some kind which initiated the DNS lookup. I get the impression it's not anything that's installed on my machine, which would explain why Microsoft Security Essentials didn't detect anything.
I also understand that the DNS lookup could have been made by any device on my network that's using OpenDNS and there's no easy way to figure out which. But, even if it happened on another device, it sounds like there's nothing I can do about it but be more careful about the websites I visit.
Sound right? Or could one of MY devices be infected?
