A "personal firewall" (basic packet filtering, user-controlled, which should be enough reason to doubt its usefulness) does not actually act as a firewall.
1. It can not detect if "explorer.exe" is really "explorer.exe" when asking you if explorer.exe may access the internet.
2. It is not that hard to write a script which automatically clicks "Allow".
3. It is behind your internet connection, so any packets passing it are already on your computer.
4. ... if they pass it anyway (there is always a way to create your own, independent TCP connections).
5. A virus, worm or trojan runs with your own user privileges, so it can easily disable your PFW completely.
Now what is the point in using something like that which also depends on the user's own "Brain 1.0"?
If you actually use software from dubious sources and click unknown links (the only ways to get infected), you'll fail anyway. A "personal firewall" can not help you.
