It all depends on what kind of precautions you've taken. If you have a router set up, that's the easiest way to prevent your computer from being seen on the Internet. Of course, if you leave the router's default password etc. the way it comes from the factory, someone could easily get into your router. So, you always want to make sure that if you get a router or any type of firewall that you do change the default settings that come from the manufacturer, because that is a very common way to have your router hacked into.
