Norton being a nice product by Symantec in Computer security but some friends reported me that they are having problems in uninstalling/removing Norton products, but luckily I have never faced this. Reasons for the removal may be several, but if you plan to remove it, it should be removed. :)
Well there is a tool by Symantec, to remove Norton products instantly. The tool first stops all running instances of Norton products and then removes them.
