We have downloaded a couple of the free firewalls from the internet, off the top of my head I am not real sure of the exact ones. After we noticed this we did run a scan and it detected 30 something virus could this have been one? My husband has used LW for a long time and he said that he had never seen a pornographic movie appear in the downloading section and the only way it could have appear is if we searched for it, which neither one of us have searched for any type of videos.
