Norton will not scan Internet Explorer Windows 7

When I attempt to do a scan using Norton (or practically any program) a bow pops up with "View downloads Internet Explorer in the top left.Within the box top left it has "View and track your downloads." In the center there is a column for "Do you want to run or save this program." (With the program name beneath) to the right of that ,buttons for Run,Save.(neither of which has any effect).At the bottom are "Clear List,Close." Is this what is called a Program Manager?And how do I remove it.Obviously I cannot scan with Norton or do any downloads while this prevents any action.It started doing this 4 days ago when I attempted to down load Explorer 11 for Windows 7 from the Microsoft site.Thanks for amy help.
