If you felt inclined, there is no reason why you couldn't securely protect your system with free security software. There are some quality tools available. These include free anti-virus applications, such as PC Tools Free Anti-Virus, AVG Anti-Virus Free and so on. Some of these need manual updates, so there's a chance you may get caught out. There are free firewalls, too, from PC Tools, the most recent Webroot Personal Firewall 5.5 and now Comodo have finally released their Vista-compatible free firewall.
Comodo Firewall Pro 3 is a new release and completely free of charge. There's a key difference though, in that this free firewall can be used for your desktop home PC or commercial use. So you can now protect your workstation from intruders through your internal network. The new firewall includes an application analysis engine to protect against software that may attack your computer from inside your network.
