re: Progress...
Unless Norton’s changed you might want to check out some other anti-virus product as its very resource hunger well I found it effected my machine some what. Unfortunately anti-virus products keep change there program core. Unfortunately not because they change it but keeping up with which ones best.
Me I use Free AVG myself just because it saves me money its faired okay when reviewed but with any product it’s a personal choice as well as a understanding it carries out what’s required.
Not sure on your choice of music ;)
