Norton messed up Sound playback on my Brand New Win 8 i5 computer

I did everything from reinstall the OS,  take out every add in card, uninstall every codec, update firmware on my optical drives, uninstall every suspect program by install date but in the end it was Norton antivirus 2012. When I say Norton messed up the sound I mean it sounded scratchy, it compressions and decompression, pops hisses and so on. No sound source was unaffected. It messed up sound from my X Fi Fatality sound card, my realtek motherboard sound card, my Creative Fatality USB headphones, and the USB sound card built into my Logitek G110 keyboard. And yes I installed and reinstalled each one of those separately.  This issue was a mo-fo. My stats are attached
