What does this gotta do with combat arms....Well, at least you know you are in wrong section.... I advice you to format your computer....yeah, everything will be deleted...

what error do you get when you try to open stuff? because you might have one of those fake AV programs.
go to
C:\Program Files\
and look for 'Windows Police Pro'
tell me if its there or not.
