This sounds like a virus. First remove the virus using http://www.sevenforums.com/tutorials/166445-windows-defender-offline.html (you will need another computer to download the file and burn to disc or put on a USB flash drive). Once you have done that, post back, and I will walk you through the steps to setup the permissions so you can get into Windows again.
