a good firewall that is free is zone alarm.

and it will block people from downloading files from your computer....unless they really have a reason to get in your computer, and if they do, then they will be able to get past any firewall that you have...
but for the general user, Zone Alarm will work fine, and keep the bad guys out.
also, scan your computer regularly for viruses...
that will help keep the trojans off your computer, which open it up like a candy store to hackers....(not the usc trojans....
