Norton hides and blocks applications. It also makes it so you cant download already blocked applications.

If its your computer, I would suggest a free copy of COMODO internet security in place of Norton. I personally hate Norton...
http://www.comodo.com/home/internet-security/free-internet-security.phpNorton also sucks up ram like none other... which makes your game run slower, which would explain the game running more smoothly now.
Ive used COMODO with no problems for a few years now, the more you use it, the smarter it gets with what programs you want running. If you do download it, dont install Geek Buddy... most
**** annoying program in the world
