I have a serious problem: I think that a hacker has broken into my network, and I am troubled. Since I created this peer-to-peer network, 3 years ago, I have only had 3 PCs on it running the following OPSYSs. 1. pc1 = Hhr (Win98 R2) 2. pc2 = Main ( WinXP Pro ServPak2) 3. pc3 = Dell (Win 98 R2) I suddenly find (it may have been there for awhile) a fourth foreign PC called: “Rongee-pc” I am certain that it has been put there by a hacker. I never had a fourth PC on the network, let alone one named “Rongee-pc”! It is inaccessible to me, whereasthe others are completely accessible. I have been using the free AVG anti-virus. I have Windows Firewall “On” with a list of exceptions (none are Rongee-pc!) I have a Linksys Broadband Router Hub, and a Cable Modem for Internet connection I am dreadfully afraid of what this hacker PC might do. Do you have any ideas?
