I need Help with facebook!

Hello,

I have a facebook and it was working fine yesterdy but then i was downloading something called ooVoo but it was still working at the time. I think it was working because i was still loged in then when i loged out i loged in the next day and it was taking a long time to load and then it sended me to a website called Freeze.com And telling me to click on facebook again and i did and it still woudnt let me log in and it sent me to the Freeze website again. I tryed to shutdown and restart my computer and wait 24 hrs. to see if it will work after i did that but it didnt work. So i thought it wasnt working because of the dowloading ooVoo so i delted it but it still wasnt working. The other websites i go to works but just not facebook well i can go to facebook but it wont let me log in and sends me to a website to try again but it doesnt work. I really dont know what to do If anyone had a promblem like this and can help me please HELP ME OUT! I have a emachines computer and windows7 with a dell desktop. So I really need HELP on this and i dont know what to do.
