Get that shit off your computer right away, in fact I'd be ready to go get another computer, cause the cop's will very likely try to take that one, now that you have told them about CP being on it
You screwed the pooch on this one my friend, the cops have very little power, or reason to care about CP that came from yahoo. I bet the question they will ask is why were you even looking at adult stuff to begin with. And if they do confiscate your system, they will see everything that you do on it. So I recommend you make backups of all your adult stuff on cd's, delete all adult related material from the system, and be ready to go get a new system if they take that one.
I've had too many webmasters that hosted with us, get toasted when the cop's got into it, so please protect yourself!!!
