How To Safely Remove Symantec AntiVirus

I currently have Symantec AntiVirus, 10.1.6.6000, Full Version.  I intend on replacing it with End Point.  I have been told that after using the Windows Add/Remove function that I should also visit the Norton Page and use one of the Removal Utilities to be sure that everything has been removed that should be removed.  I visited the Norton Site and looked at the Removal Utilities but it asked for the year of the program which I am not sure of I believe it was 2006 when I first installed the program but it may have been 2007.  Can anyone tell me what year Version 10.1.6.6000 came out?  And if I use the wrong Removal Utility will it damage my system?  I would appreciate any and all replies and will thank you in advance.
