@burnout426 the hijacked page must be doing a crude browser fingerprinting before rendering the fake update page, since you are getting one for Chrome, but not Opera, whereas I got one on Opera. All I can tell you about the condition that triggered the page for me on Opera was that I installed Opera 1 week prior to that, and everything was on its default setting - no additional plug ins.
He got the hijacked page on Opera, and you got the hijacked page on Chrome. I suspect that the hijacked page rotates the target browser so as not to alert the site admin that it was hijacked. That way if one user on Chrome gets the drive-by and alerts the admin only for the site admin to check out the site on Opera, he would see a normal page with no driveby and would more likely suspect that it was the user's machine that was hijacked rather than the site. Either way, at least I know that Chrome will ask it's users if he wants to proceed with the download, if there is an attempt at a drive-by download. So in this regard, Chrome isn't as trashy as Opera.
