A little house cleaning might be a good place to start. As I was reminded a few days back, CCleaner is an excellent tool for finding and deleting unnecessary clutter from your system. A clean system operates smoother and faster. You can get it at www.ccleaner.com/download/.
Also, check for unwanted programs in your Startup menu. Start - All Programs - Startup.
You can delete what you don't need starting up at boot.
Additionally, the msconfig utility is a great tool for systematically stopping programs to see which, if any, particular program is causing the problem. Start - Run - type "msconfig" w/o the quotes -- OK. Open the Startup tab to select / deselect programs.
Last, but not least, even with Norton on your system there is still the possibility of a infection. No anti-virus program catches everything. So, it's a good idea to have more than one -- you can download several free anti-virus programs from places like download.com. Avast is a good one. You can also go to www.trendmicro.com and run an online scan for free.
Also, if your Norton doesn't do it, download a good anti-spyware program (Spybot S&D, for example) - keep it updated and use it regularly.
I hope something in all of this helps you out. If not, hang on -- someone will be by before long with other suggestions.
