In reverse order - you should be running antivirus software, as well as a firewall and spyware protection. If you're considering freeware security applications, you can choose from the following:

firewall: (listed in order of preference)

Comodo (http://www.comodo.com ), or

PC Tools (http://www.pctools.com/firewall )

Comodo recently released version 3.0 of its firewall, which adds an intrusion prevention component that's very effective, though it does take time for it to learn your system, and requires some ongoing attention by the user to make sure programs don't get improperly blocked. Comodo is one of the strongest firewalls available, freeware or commercial, according to the independent testing site matousec.com.
