Any particular program locking up?
As for Excel, you may need to reinstall Office.
Please, post some computer info:
- processor type, amount of RAM (hold Windows logo key, hit Pause/Break key)
- hard drive size/free space (open "My Computer", right click on hard drive letter, click "Properties")
BTW, I'm not a big fan of Norton, if you don't know yet
