I too have seen the advertisements become more and more vicious. I also experienced the same automatic virus download that you did. I'm sure the mods/Raz are trying to figure a way around this as it's starting to get worse and worse by the passing months. The NSFW ads don't annoy me personally, but I see how it can make small children feel uncomfortable, especially when FeralHeart is a game suitable (and targeted) towards such a young demographic.
I really do hope that Raz can find a way to either decrease the number of ads, or at least change the ads to a more suitable theme.
