I have five computers in the network, all identifiable, and another one, called Anonymous. I have two workgroups, and Anonymous is in both of them. I connect all computers either wirelessly or wired through a router/modem wireless. I have zonealarm and firewall, wpa password set on router/modem. Then after 30 or so minutes, anonymous disappears!?!? What is the possibility of this being a ghost? I never had this pop up until recently. Did virus check and nothing came up. I'm concerned someone may have hacked into my account. I recently installed Windows XP Black on one of my PCs (pirated), and sometimes I wonder if people who create these pirates can have access to your computers?
