There are some TROJANs ( 1.exe / 5.exe / 1explorer.exe ) in my computer , i google their file name and found out that , i used Ad-aware/AVG anti-virus/s&d/Spyware Doctor/AVG anti-spyware to scan and try to delete them but none of them works , it will still be there when i open up the task manager , so anyone know ways to get rid of them ?

Thanks
