I will suggest an actual suite, as I use Norton Internet Security myself.

It has what you ask for, and that is what you will need, too. An anti-virus solution, firewall, and not only a spam blocker, but also one for pop-ups in your webbrowser, too.

Also, getting an all-in-one package has the advantage that the programs recognize each other, don't prevent each other from working and really cover you against different risks.
