macro that make hyperlink?

Hey guys
I am trying to turn a url string into a clickable hyperlink, using the following macro:

Public Sub Convert_To_Hyperlinks()
    Dim Cell As Range
    For Each Cell In Intersect(Selection, ActiveSheet.UsedRange)
        If Cell <> "" Then
            ActiveSheet.Hyperlinks.Add Cell, Cell.Value
        End If
    Next
End Sub

the problem is that instead of making a link like this http://example.com I am getting a link like this file:///C\users\deski\desktop\example.com

See file attached

How can I fix that? thx a lot!
