how can i block a facebook profile from my computer?

[luigi]

my sister is always using facebook on my computer. I allow her but she abuses it. everytime I go out and left my computer she always opens it and uses facebook. Can i block her facebook from my computer? I dont want to block facebook from my computer because i sometimes chat in facebook. Can someone please help me. I just want to stop it because she doesnt do household chores because of facebook so im always the one who gets blamed.

instead, just make sure to log out of your windows account when you walk away from your computer, and make sure you have a password on every windows login that she does not know

Well there are so many ways to interact now days - which ones will you keep blocking - my suggestions - lock your computer rather - put a windows password and lock it - she wont be able to open up anything if that"s what you want.
