Over the last few weeks, when I visit MacRumors, I get a popup saying that a virus has been detected and a scan needs to be done. I close the window and it starts up a second window and starts a scan, so now I shut down the process. This has been under Win 7 64 IE9 with windows MSE running. I guess most of you run only the Mac OS, but I run a dual boot setup and need to use Windows right now. It sounds like one of those 'code injection' things, but I'm no expert.
