safe firewall settings?

[Chris Berry]

Just got a nasty surprise when configuring my firewall.
I thought I'd be bright and enable the multi-DMZ settings and give my main
PC a WAN IP address.
Lo and behold, seconds later there was and IRC backdoor trojan file
(msgfix.exe) created on my PC duly detected by NOD32.
I abandoned the WAN IP address thoughts I had.
before I could change the settings back, internet access was disrupted.
Next thing, I find a winbasic32 process running - killing this restored
internet connectivity.
i've scanned those files and didn't find anything.
How can I be sure that there's no longer an infection?
Thanks.

Probably by cleaning up the registry and deleting files according to
one of these descriptions which are easily Googled up:

Cleaned up the registry. I thought that NOD32 was supposed to provide me
with good protection against this sort of thing.
I'd really like to know what else was touched by the back door attacker.
