My computer seems to infected by the WinNT/Alureon.D Trojan, which is detected by my McAfee anti virus. But the anti virus is not able to delete it stating that close other applications using this program. Even though I do not have any applications running the anti virus still gives the same message as close other applications using this program. How do I remove this trojan. Even it gets transfered to the removable media connected to my computer. I am using Windows Vista operating system.
