Okay, this is seriously weird. Now IE balks on opening the CNN story, Downadup virus exposes millions of PCs to hijack. And it also did this a few days ago on a Vista story. I haven't seen this behavior on any non-MS news items. Is this pure coincidence?

It did that for me at first, for both pages. It displays the whole page, then decides there's a problem and bails out.
But then I went to the CNN home page and followed the links until I found the downadup story, and then I could load it just fine. It also displays the Zune 2K9 story just fine now, even if I paste the URL into the address bar. Even if I close IE and then reopen it, the problem doesn't happen any more.
