The boot virus code is one sector in length with the infectious code being stored at side 0, track 0, sector 1 and the original master boot record code being stored at side 0, track 0 sector 2. On floppy disks, Stoned.Angelina calculates the last sector of the root directory and uses this location to store a copy of the original DOS boot sector.

In addition to standard viral replication, Stoned.Angelina contains a block of code designed to stealth (by means of redirection) any reads to the physical location side 0, track 0 sector 1 on both floppy disks and hard disks.

Contained within the virus code body is the following encrypted text, which is never displayed on the screen:

You must use the fdisk /mbr command to repair an infected MBR. Please read all instructions before you begin.

CAUTION:

  • The procedure described in this document could result in the loss of all data on the computer if not done correctly. Unless you are completely familiar with the use of the DOS FDISK command, we suggest that you obtain the services of a qualified computer consultant.
  • If your computer uses a Dynamic Drive Overlay, or if you are not sure, first follow the instructions in the document How to repair a virus when using a dynamic drive overlay or a disk compression utility.
To remove the virus:
  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 into 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 you can create one on an uninfected computer:
      1. Insert the first, write-protected disk of the Rescue Disk set into 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.
