But dont you find it very annoying? I used it for a few days but got so fed up with them little things popping up, asking if it wants my anti-virus to connect to the internet <lol>
Zonealarm on Vista is a no-go. ESPECIALLY if you are using Firefox, i found that when using Firefox for more than 30 mins (and uTorrent), the program would crash and just hang on to processes, having to do a hard reboot.

I use Avira, which is better than AVG in my eyes, less memory usage, and easier interface. I also recommend a Firewall called PC Tools Firewall Plus, little annoyance and free online protection.
