I recently got infected with search.babylon.com in google, so I deleted google, then restored to a previous point a few days before the infection.  Now the hyperlinks in my Windows Live Mail give a popup box with a big red X and an error message "...... is not a valid Win32 app".  Is this yet another virus that Norton can't handle, or is Windows Live Mail corrputed and needs to be reinstalled?  If so, how do I do that?
