Okay, I just wrote a long detailed account of what's happening, and the hacker sent me somewhere else when I tried to post it. Now I have to start all over. Here are the facts: I'm normal and don't do anything weird on my computer. I have a G4 powerbook with Tiger and Vonage (not sure if that's considered a router) and an ethernet connection. I know how to set up all my preferences, I don't want to share anything. I want to use my computer and my internet by myself. It always starts out with my network config changing to "Internal Modem." Then my location changes, then my (LOCKED) system preferences are unlocked. The "Network Time" box will be checked. My firewall keeps getting turned off. My IP Net Sentry is suddenly set up to receive packages, and there are hundreds of scripts and Python and Network time, users named "Other", etc. So, okay, I will do a clean re-install because I can't have anything on my own computer because of this. I unplugged everything and in the morning, I put my Tiger disk in. I have two hard drives so in disk utility, I was doing a 7 pass secure erase of Other's hard drive but WHILE I was erasing his, he changed the name of my hard drive and put all his stuff on there. He even made my install show the languages and Welcome Screen at the end of Disk 2! He's always one step ahead of me and I've read and read and read, but what good do any of these usual solutions do when he is obviously root user, because I can't open Net Info at all. He has set an open firmware password. When I was trying to reinstall, I wasn't even hooked up to my ethernet! He connects to me with Internal Modem and it says BUS: ATA Device 0 for him. (the ominous "Other") I swear he made my last message to you go away too. Please don't think I'm crazy, I'm not! I just don't know what to do to get rid of this thing! I have a G4 tower I'd love to use because of the big monitor, but I can't. You guys are my ONLY HOPE. You are the real "geniuses." You guys will love this. I had a new Mac Mini, same thing. It (he) was controlling everything in my new Mac, so I took it to the genius bar. One of the geniuses (LOL) is looking in the hard drive after telling me that what I was saying "wasn't possible." But he sees everything I told him, but he pretends he doesn't. Another genius comes by and excitedly says, "LOOK! IT'S THAT..." when he is abruptly silenced by his superior who is now standing behind him. He shakes his head cryptically and gives him a disapproving nudge. Because they must not break THE CODE. They must protect the Mac's reputation. UGH. Thankfully, before I left, (he insisted I had a BAD HARD DRIVE) he regaled me with his vast wisdom, by saying (with his brow furrowed) "You know... you could stay off the internet. That would solve your problem." I stared at him blankly. He was serious. Please help me you guys. There has to be something I can do! If you need more technical info, just tell me! What steps can I take when he (OR IT) is there even when I'm not on the internet and doing a re-install! What good does anything do when he controls every setting and app.? I'm going to get this to send somehow. Thanks for listening, Julie So maybe I'm paranoid, but who wouldn't be! Even if I was, this stuff is really happoening. I don't need attention, and would so much rather be doing something else with my time, I promise.
