In your case, because you live with this particular "spy", you have few options.. If it were me, I would move. Simple as that.. Why live with a criminal?
If that's not an option.... First, I would reformat the computer and reinstall everything from scratch. (I know you've done that already but it's time to do it again.) Next, I would stop accessing the internet at your home and use a connection elsewhere.. Next, I would access all of my email accounts and change the passwords to something complex..
Hope this helps.
My roommate has created an internet gateway that he is using to spy on me all the time. I have tried many things to to get away from this including blocking his MAC address but then I can't get an internet connection on my pc. The internet service is under his name while I have control over the DSL modem with built-in router. I had even purchased another router in hopes that it would create a firewall but in the effort to create a password for it, I had to go online and once my roommate knew the brand and type of equipment I had then he just added it to his internet connection list in Vista and now I can't get a connection if I use that router. I myself, am using Windows XP.
Any help would be greatly appreciated as I would like to look for another place to live but I do not want this creep knowing where I will move to, not to mention he is violating my privacy with my attorney and my Visa card. I am not very literate when it comes to computers so I will need elementary instructions. Thank.
