The router does provide a firewall by default. It does this by not responding to any unknown request. Meaning when you go and surf you send a request for the page and the router waits for and accepts the incoming response, but say the sasser worm scans your IP and tries to connect to your router, the router does not respond to that request and drops the packets. The only thing the router doesnt block is outbound requests from the local computer, so if you have a trojan on your computer and it send a response to a website to downloard a program the router will not block this. Also Windows XP SP2 firewall only blocks inbound requests.
The first thing you need is a good antivirus and to keep it updated I personally suggest Avast Home version, its Free, does realtime scanning of your computer, and it does automatic updating. If you do a lot of downloading or use program with spyware I would suggest you do install some type of Software firewall, Zonealram is a good one.
