You need to give more detail. Do you mean any visitors to a website you own keep seeing pages from surveys.cnet.com or when you browse the internet using your browser all you see are pages from surveys.cnet.com?
If you visit any pages of my website, the visitor will be re-directed to a blank page 'surveys.cnet.com'.
I was thinking the same thing but this issue only occurs within Firefox 3.6. I just tried the latest IE and actually Firefox 4 Beta, no problem at all which is why I'm not jumping to such conclusions.
Something lurking in your FF browser then. Sounds more likely, especially if it doesn't happen with other browsers / visitors to your site. You've maybe been hit by a drive-by download.
Problem solved. Seemed there was a bug within the actual router. Had to reset it from the back and perform an ipconfig/flush from the command prompt.
