Heather doesn't mention that if you're a heavy P2P user, then a software firewall probably isn't a good idea. Many if not most of these, deliberately or otherwise, interfere with such programs, making them pretty much unusable. There is usually no sign of what is causing the problem, it just doesn't work.
If you have any sort of broadband connection (DSL, Cable, etc.) then your modem contains a router which also incorporates at the least a NAT firewall and quite possibly a SPF (Stateful Packet Inspection) firewall as well. This will protect you from real-time threats from outside at least as well and probably better than any software firewall. You should verify in the documentation that came with your modem that it actually does have this feature, then verify that it is actually turned on. If it has and it is, you don't need any other kind of firewall.
Hard to believe Heather writes articles professionally, as she can't spell "separate" and doesn't seem to know what the apostrophe key is for.
