Be careful smss.exe could be a system file, see the link http://www.liutilities.com/products/wintaskspro/processlibrary/smss/ and http://www.neuber.com/taskmanager/process/smss.exe.html check fully before you delete anything.
What made you think that you should be trying to get rid of smss.exe?
A search of google.com for smss.exe returns many hits.
