Its just one of those stupid pop-ups that come on the screen.I try to click it off the screen to get it off but it instead directs me straight to the damn site.This happens every day.
More than likely you're browser was hijacked. This is when you try to close a pop up window and then as you do the redirected website launches automatically. Doesn't have to be porn site, could be just an ad site. You have to get this cleaned out. Tell your IT guy and they will either clean the infection in the registry or take the easy way and re-image your computer.

Some parasites violate user privacy. They disclose user’s personal information to advertisers and even hackers. Malicious persons use browser hijackers to track user activity in the Internet, find out their victim’s name, contact information and even steal priceless identity data, which then can be used for unclear purposes.
Browser hijackers that are associated with pornographic resources set adult web sites as home or search pages. Such behavior not only shocks a user, but also may cause some serious troubles. There are real examples of people who have lost their jobs because of explicit content found on their computers at work.
