does anyone know how to prevent hackers from getting into you computer? My friend just had someone shut down all her programs and a window came up that she has never seen b4 and said they were gonna change her passwords if she didn't show them her tits. Which she didn't. Then he said to restart her computer to get rid of his shit. From what i understand yahoo is recording ev1s isp address so maybe someone hacked into yahoo IM. He said he was the master and she was the slave. Very scary
