To remove this Trojan you need to download an anti-virus software called AVG by "Grisoft" (Search on www.Google.co.UK to find the website) It is FREE to download. Free updates and removes all trojans/virus's. I thoroughly recomend this. When you download it, update it (FREE) and run the complete test this will remove it and free your computer of this Trojan.
If the virus is in the system volume information AVG will not pick it up. Follow the steps in this page and run AVG again. AVG should have picked up your virus this time. (You have the option in AVG to run a custom scan where you can set it to scan the system volume information only).
The spyware program 'PestPatrol' will remove it.

just run a antivirus scan.
Simply run the AVG anti-virus, which can be downloaded for free from the their official website I think you have to find all the maps called 32warn, and delete them. And you have to find the program that bring the horse in, a program installed about the day you saw the Trojan horse, and delete it. I have done it.

I think that some more info is needed like what operating system you use, have you tried to do it from a bootscan, what virus detection system do you have before this can be answered.
I had this virus and Panda online scanner removed it! pandasoftware.com
