I believe my computer has been "hijacked." When I turn it on, it goes to a blank desktop and a Welcome to Windows note comes on every time as if I'm using the computer for the first time. All my folders and documents are gone, but when I do a Search for a document, it shows that it's in the computer, but then won't let me access it, gives me an error message. I am desperate. Can anyone help? Thanks.
