Trying to select cell "A1" in excel vba after selecting a range

At the end of an excel vba program I select all the columns being used and set the columns to autofit with the following code:    
 
ActiveSheet.Columns("A:I").Select
Selection.Columns.AutoFit

That however leaves the columns highlighted.  I tried  

Range("A1").Select
Range("A1").Activate                                                

but it didn't have any effect.  If I use

ActiveSheet.Columns("Y:Z").Select

two columns off the screen are highlighted which clears the main area but still leaves another area highlighted.  What I want is to select cell "A1" which when I do it manually clears any highlighting.  Is there any way to do this via vba?
