You can get a very good, and free, check on how "bulletproof" you are at Symantec Security Check. It's among the first checks recommended by the majority of the better on-line help sites. Click on the "Scan for Security Risks."

If you have a firewall, it will probably ask you for permission to "penetrate" it. (Different from asking you to turn it off, which is a little scary?). It's fairly quick, and it will give you a pretty complete report, with suggestions for what you can do to get better. While it will of course suggest which Norton/Symantec products can fix things for you, it gives you pretty complete descriptions of what any holes are. Knowing where you may be vulnerable can be a lot of help, and you're free to use other products. No real pushing of the Norton stuff.
