Not that I'm implying anything about your internet habits, but those pop-ups are not always linked to the site you're currently visiting. Often times they are based on cookies or other factors in your web history, possibly a malware program. But AnF or Microsoft are not responsible. I had a porn pop-up when I was on a university website.

I've been infected with Gator(?) twice. I think that I got it from typing a website name that seemed "obvious" but was actually a bottom feeder site that bought up "internet real estate".

I wasn't directed to porn but I did get "random" popups (including some that launched while I was reading FR). AdAware and Spybot Search & Destroy both help to keep my system adware/spyware free.

The website that I did get looked like a search engine (and immediately I got a popup asking to let that site become my homepage); some other sites don't even ask.

As I say, these "businessmen" are bottom feeders.
