Dont know if this applies in this area but i dont know where else it would go so sorry if it doesnt fit the category.

previously i was speaking too an ex friend who I didnt wanna see anymore on a website "meetme.com" after the conversation ended abruptly he took over my computers MOUSE and keyboard for about an hour. I was would like too know how he did it and how I can fight this. I know it was him because of what he was typing while I had notepad open.

- thanks to ANYONE who can help!Some of the PEOPLE on the Microsoft forum say that it can happen.
Unauthorized Remote Access

    If you connect to the internet DIRECTLY from your Computer to a Modem, consider purchasing a Router and placing it between your Computer and the modem.  A router will block most all unexpected inward connection attempts to your network.
    If you have a Wireless Router in your network, make sure you have wireless security enabled.  WEP security has been cracked.  WPA2 is currently the best CHOICE for security on your router.  Pick a good password.
    If you have XP Home or XP Pro with Simple File Sharing enabled, deactivate the Guest account.  All network connections will authenticate through the Guest account.  To do this, bring up a command prompt window (Start -> Run -> "cmd") then enter the command:     net user guest /active:no
    If you have XP Pro with Simple File Sharing Disabled,  then make sure the "Administrator" user has a password (by default, it doesn't).  Also make sure all users on your computer have passwords in place.
    Consider installing a Firewall product on your computer.
