In our local paper there was a story about a man and his wife who went through hell when a hacker had stored illegal images on his computer without him knowing. It wound up costing him his job and lost everything with legal fees of $250,000. The reason for the story was that he was arrested and later proved by his legal team that he had no knowledge of those images being there and they proved it was a hacker. The article also stated it wasn't uncommon for them to slip stuff on others computer without their knowledge then access it.
My question is is there a way to do a search for any and all pictures that may be on your computer to make sure the same hasn't happened? I know not long ago I was locked out of Admin privileges and had to completely redo back to the beginning .
