I cannot go to sites with adult content suddenly, I have not changed any settings. I can get to all of my other bookmarked sites however.

Any error message for those websites?

Any other users on that PC who have Admin permissions, who might have installed some Parental Control software that you aren't aware of?

ed-meister, No, I am the only user. I checked for these controls at my control panel level, do I need to check anywhere else? Thanks, Klondike Mike
