opinions on Trojan appz

I installed protowall w/ blocklist. I noticed a port being used by kuang2TheVirus.
I have Symantec Corp 9.0.3.1000 3/25/2005 installed.
I used Trojan Hunter and found 0.
Tested PC DoorGuard 3 and found 4.
What do you think is/are the best trojan appz?

Kaspersky & ewido are my solution.

A2free is what i use along with Nod32,Ad-Aware and SpyBot behind ZoneAlarm
