Anti-Virus can try on avast! or AVG.

Anti-Spyware can try on Windows Defender or Ad-Aware (2007 version not Vista ready yet)

Firewall I suggest remain using Windows Firewall.

Windows Live Onecare! I had Norton 360 and I do have windows 360 but it damaged my computer..some files could not open..it interfered so much. Maximum I had it was 2-3 days I had to take it off and reboot the computer to get it back to its original settings. Windows Live Onecare has a 90 day Trial that u can download on their website and it works good, it has everything rolled into one.
