Yeah, yellow light. I was horrified, but figured I'd wait...and it payed off. No security software. I do think, however, that IE9 is doing something funky with caching pages (I did have to close my browser, and no, the gateway IP didn't change). Perhaps Firefox or Safari is a better bet.
Stable as ever now, though (heavy use, 2 Xboxes + PC gaming simultaneously over the very hot weekend).
