Just to start the ball rolling.
Your statement "when trying to goto certain pages" needs defining. Is it a secure site, bookmark or link?
Which web browser are you using?
Have you ran full spy-ware/virus scans?
Is this Norton Internet Security?
Even turned off it is still active.
What is the security settings of your browser?
Others will add to this list as more information becomes available.
