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?
