The general trend in viruses nowadays isn't aimed at wiping files on your C: drive or damaging your computer hardware. They are aimed at installing themselves in your system as rootkits or bots. From there they can either execute themselves as virtual machines or pesky applications that will take forever to get rid of because they launch with a new .exe name every time.
I had one guy at work who brought his laptop in because he couldn't get out to the Internet. He was using his laptop at home plugged directly in to his cable modem (not using a Linksys or other home router) and got a virus that hooked into his network connection as a proxy. When I ran a netstat -a from a command prompt I saw established network connections to a .hk domain name.
And this guy didn't open an infected e-mail or browse to a malicious site or anything - he just had his laptop directly connected to the Internet. It is my recommendation that everyone put there home computers behind a home router, even if they just have one machine. It may not protect you from a serous hacker or opening an infected e-mail - but it will protect you from viruses that scan you Internet IP for open ports and infect your pc through those open ports.
We provide all of our users with Linksys home routers when we give them their laptops. $50 of expense will, in the long run, save you from a days worth of frustration cleaning out an infected machine by hand whe even your AV software will not detect and get rid of all traces.
