Why Anti Trojan tools?
Trojans open your PC from the inside to attackers, which enables the person/website who sent the Trojan to monitor your PC. Trojans come in various varieties; some of them are Downloader (which downloads the malicious programs without user's knowledge), RAT (Which allow remote controlling of infected PC) etc.
All Trojans are not detected by AntiViruses as these Trojans does not behave like a Virus. But AVs can detect some of the common or (in)famous Trojans.
But for more security against Trojans, specialized tools are required; this is where Anti Trojan softwares come into picture.
Two of the most popular Anti Trojans are TrojanHunter and Trojan Remover. Both are commercial softwares, with 30 day trials being available for download.
Enter TrojanHunter:-

Main features
TrojanHunter has two modules built into it, namely Scanner and Guard. Scanner is the On-Demand Trojan scanner, whereas Guard is the Real-Time scanner which automatically scans the executables, DLLs and other files for Trojans.
User interface
TrojanHunter Scanner has a no-nonsense clean look, which is very easy to use. Scanning the system is a simple process. There are three types of system scan namely Quick, Full and Custom.
Quick Scan scans only registry, memory and system files whereas Full Scan scans all the files in all the drives and Custom scan allows scanning the specified file/folder/drive.
Quick Scan as the name suggests is very quick and takes a few seconds. Full Scan takes a longer time depending on the drive size.
Scanner features
Scanner can scan inside archives like Zip, Rar, and Cab etc. It can scan NTFS Alternate Data Streams which is a favorite hideout for Spywares.
Apart from scanning, TrojanHunter consist additional features like Process Viewer, Autostart Viewer, NetStat Viewer, Window List and MemString.
Process Viewer provides an exhaustive list of the Process and files related to them, and it's possible to kill the unwanted/suspicious processes.
AutoStart Explorer is again a very good tool, which provides information about Progams which start automatically when Windows starts. It lists auto starting programs from registry, startup folder, batch files, executables, .ini files, services and others. Also provides description about the programs that are listed there.
Window List is a unique tool which lists all the windows/module that is opened, both visible and invisible.
MemString displays programs in memory with their PIDs and there is a facility to extract strings from those processes.
Apart from these tools, it consists of several Plugins which perform specialized tasks. Some of them are Registry Checker, INIfile Checker, Port Checker, LSP Checker, Script Checker etc. In a Quick/Full/Custom scan all these plugins are automatically executed.
Guard Features
Guard is the real time scanner module of TrojanHunter. It scans for predefined file types which are used by Trojans, like exe, dll etc.
Surprisingly, Guard is very light on System resources and it does not cause any delay or lockups while opening/executing programs.
Guard has features like automatic cleaning of detected troajns, automatic updates which take place in background.
Performance
This is the important part of any anti malware software. TrojanHunter is regarded as one of the best tool for detecting and removing Trojans. And it is true indeed. Even though its Trojan database is not the largest around (TrojanRemover has more detection rules), frequent updates and real time scanner help to keep the Trojans at bay.
One of my CDs had a Trojan (it was a Trojan in the guise of Password recovery tool for archives!) which was not detected by Norton, AVG, SpyBot, AdAware and a2 Free, but TrojanHunter detected it promptly giving all the information like file name, Trojan name and an option to clean it.
I tested it with PC Security Test 2005 software, which tests the detection capacity of AntiVirus, AntiSpyware/Trojan and Firewall. When it simulated a Trojan running in memory, TrojanHunter's Guard popped up and showed the Trojan name/file and an option to clean it and it cleaned it successfully.
Cleaning is done by changing the File extension to .TCF, thus by preventing it from running again. Along with this, its registry entries are also removed.
Update process is automatic, but trial versions don't get an update.
And finally....
TrojanHunter is a good tool with rich set of features, database and also very easy to use. It's recommended to try out the 30 day trial version, and remove all those Trojans which may be lurking in your System.
