A firewall is solitary as polite as the rule set that you set on it and the whereabouts that you hold as a user on the system. For example, if you're acceptance a popup on your computer axiom to "click here to support your computer" and you do it, you may enjoy be tricked to installing spyware or a trojan on your system. Your firewall next become invalid, especially if it's Windows firewall. Windows firewall doesn't block outgoing connections except for ICMP (pings) and cannot stop anything disappearing the system. It lone blocks incoming packet. As they other say, your best defense is a right offense.
You can run an intrusion detection system (IDS) on your computer that should detect when something happen that wasn't expected. For example, someone sends you a malformed packet designed to crash your system. The IDS will detect it and when configured as an IPS (prevention), it'll block the packet. You can use Eagle X for this (linked below).
You should other run antivirus and antispyware software on your computer. AVG make programs for free.
You have need of to lock down your computer and not log on as an administrator in rank to stay out of harm`s way. Otherwise, no issue how immobilize your system is, the administrator can override anything lock downs you enjoy established. I suggest reading the Microsoft XP Security Guide to lock it down. This is what NSA suggests doing next to some extramural change to what MS recommend. See the second connection. If that doesn't work, turn to www.nsa.gov/snac and to Operating Systems, Windows XP...
Turn on the firewalls and IDS's for your cable and DSL routers and don't allow all outbound ports to venture out. Specify the traffic that you use and no more. So, for example don't allow TCP 139 out of your lattice basically because your window box is running it. Instead, evaluate what you stipulation to run (http, https, telnet, limewire, etc) and set those ports to allow from the inside gridiron to the Internet nouns. Everything else should be denied and logged. This opening you can at smallest see what's trying to turn out and exploit appropriately to try and ensure that you're not owned.
The stuff I mentioned here applies to home networks. I own a separate and more extensive record for organizational networks. It includes these steps as ably as doing things similar to setting up a proxy server and requiring adjectives HTTP/HTTPS/FTP connections to walk through it, versus going straight to the Internet. It's much more extensive, but for measurable reason.
