A router is a small box that sits outside your computer. It serves a dual purpose: to allow multiple computers in your house to use the same internet connection (as oppose to paying extra money for each computer to have its own internet service) and it contains special software (known as firmware) that scans incoming and outgoing internet traffic for potentially malicious activity (i.e. someone attepting to hack your computer). You would connect your computer(s) to the router and connect the router to your modem (most likely a cable or DSL modem if your using a router). I find that my router works better than any internal software (such as Macafee). The router doesn't slow my system down (because it runs as its own separate device) and it automatically recognizes good traffic from bad traffic (I had some configuring to do but not much). The router also allows me to add computers to my internet connection, should I choose to do so. Personal routers generally cost between $50 and $150 depending on your needs (IMPORTANT: these prices are more if you want to use a wireless router, meaning a router where you woulnd't need to run cable through your house, which can be a huge pain)

In your case LUVBUGZ, I would stick with the Macafee software. Protection is always a good thing. You might also want to ask the person you borrowed the software from on how to configure it properly. This way the firewall is working at its best efficiency while not getting in the way of your internet activity.
