If your modem is also a combination router then no, you don’t need a(nother) router. But the reason for using a router, even if you have only one PC is that it acts as a firewall between you and the internet. Otherwise your PC is directly exposed to the internet and all of its evildoers. Even if you have firewall software on your PC (don’t even think that Windows Firewall is real firewall protection), the internet is right up at your door. The best protection is a hardware firewall (so that the internet doesn’t even get to your door) together with a software firewall.
