    You have to create a rescue disc and boot from it and let the AV program remove it.

    More info at www.symantec.com and www.nai.com.

    Here's what Norton says:
    1. Shut down Windows, and then turn off the power. Do not simply press the reset button.
    2. Wait 30 seconds for memory to be cleared.
    3. Do one of the following:
    *If you have a NAV 2001 (or later) CD, and your computer can boot from the CD-ROM drive:
    1. Insert the NAV CD in the CD-ROM drive.
    2. Restart the computer and follow the prompts.
    3. Choose to repair all infections.
    4. Remove the floppy disk, and then restart the computer.
    5. Start Norton AntiVirus, and run a full system scan.
    *If you have a current Rescue Disk set, or can create one on an uninfected computer:
    1. Insert the first, write-protected disk of the Rescue Disk set in the floppy disk drive.
    2. Restart the computer and follow the prompts.
    3. Choose to repair all infections.
    4. Remove the floppy disk, and then restart the computer.
    5. Start Norton AntiVirus, and run a full system scan.
    *If you do not have a clean Rescue disk or a NAV 2001 (or later) CD:
    1. Insert an uninfected, write-protected, bootable disk that also contains the FDISK
    program into the floppy disk drive, and then restart the computer.
    2. Type the following, and then press Enter:

    fdisk /mbr

    3. Remove the floppy disk, and then restart the computer.
    4. Start Norton AntiVirus, and run a full system scan.
    Good luck!
