start from today every time i start the computer an error message will pop up say windows defender application failed to initialize bla bla bla..
the windows website http://www.microsoft.com/athome/security/spyware/software/default.mspx suggests "Windows Defender (Beta 2) expires December 31" so the problem is bcos the stupid computer try to start the thing but not allowed bcos expired isit?
then how to stop the computer from trying to start the thing? i cannot even delete windows defender.. it says one of the files is 'in use'

computer problems really make me mad
