I've just purchased a DIR-825. I inserted the set-up CD and McAfee identified a trojan on the CD.  The trojan is Artemis!85D19F6EB253.  Now, that I look closer, the part number starts with a B, not a D...As in BIR825 not DIR825.  I know this is a revision B1, but does that change the part number as well?  How can I be sure I'm dealing with a true D-Link 825?  And, has anyone else reported this issue with the installation CD?
