Feather

My habits are not the issue. I have a family member here who I believe is the culprit.

I'm not quite sure how all this stuff got in my computer, but there are numerous porn sites in my registry. I'm guessing it came from pop ups when I've surfed the web? I've deleted the obvious ones, but how does one set CCleaner to scan and get rid of all of them? It's really nasty I want this stuff gone!
