I'm really confused, I only have a basic knowledge of computers. I have an eMac version 10.4.11 and this suddenly appeared on my screen: http://i43.tinypic.com/sgomsz.jpg a message came up saying my computer was infected with various viruses and started doing this scan. Please someone explain to me what all of this means and how to fix it. Thanks. Any help is appreciated. I'm freaking out here.
