The following instructions pertain to all Symantec antivirus products that support security risk detection.
  1. Uninstall the security risk.

For specific details on each of these steps, read the following instructions.


1. To uninstall the Security Risk
    1. On the Windows 2000 taskbar:
      By default, Windows 2000 is set up the same as Windows 98, so follow the instructions for Windows 98. If otherwise, click Start, point to Settings > Control Panel, and then click Add/Remove Programs.

    2. On the Windows XP taskbar:
      1. Click Start > Control Panel.
      2. In the Control Panel window, double-click Add or Remove Programs.

    3. Click "The ABI Network-A Division of Direct Revenue"


      Note:
      You may need to use the scroll bar to view the whole list.

    4. Click Add/Remove, Change/Remove, or Remove (this varies with the operating system). Follow the prompts.

      Note: After running the Add/Remove programs applet, all the files may have been removed. You will want to run a full system scan to ensure that this is the case. However, it is possible that no files will be detected after using Add/Remove programs.


2. To update the definitions
To obtain the most recent definitions, start your Symantec program and run LiveUpdate.


3. To run the scan
  1. Start your Symantec antivirus program, and then run a full system scan.
  2. Take note of the names of any files detected.
  3. If any files are detected, and depending on which software version you are using, you may see one or more of the following options:

    Note: This applies only to versions of Norton AntiVirus that support security risk detection. If you are running a version of Symantec AntiVirus Corporate Edition that supports security risk detection, and security risk detection has been enabled, you will only see a message box that gives the results of the scan. If you have questions in this situation, contact your network administrator.
    • Exclude (Not recommended): If you click this button, it will set the risk so that it is no longer detectable. That is, the antivirus program will keep the security risk on your computer and will no longer detect it to remove from your computer.

    • Ignore or Skip: This option tells the scanner to ignore the risk for this scan only. It will be detected again the next time that you run a scan.

    • Cancel: This option is new to Norton Antivirus 2005. It is used when Norton Antivirus 2005 has determined that it cannot delete a security risk. This Cancel option tells the scanner to ignore the risk for this scan only, and thus, the risk will be detected again the next time that you run a scan.

      To actually delete the security risk:
      • Click its file name (under the Filename column).
      • In the Item Information box that displays, write down the full path and file name.
      • Then use Windows Explorer to locate and delete the file.

        If Windows reports that it cannot delete the file, this indicates that the file is in use. In this situation, complete the rest of the instructions on this page, restart the computer in Safe mode, and then delete the file using Windows Explorer. Restart the computer in Normal mode.

    • Delete: This option will attempt to delete the detected files. In some cases, the scanner will not be able to do this.
      • If you see a message, "Delete Failed" (or similar message), manually delete the file.
      • Click the file name of the risk that is under the Filename column.
      • In the Item Information box that displays, write down the full path and file name.
      • Then use Windows Explorer to locate and delete the file.
Important: If you are unable to start your Symantec antivirus product or the product reports that it cannot delete a detected file, you may need to stop the risk from running in order to remove it. To do this, run the scan in Safe mode. For instructions, read the document, How to start the computer in Safe Mode. Once you have restarted in Safe mode, run the scan again.

After the files are deleted, restart the computer in Normal mode and proceed with the next section.

Warning messages may be displayed when the computer is restarted, since the risk may not be fully removed at this point. You can ignore these messages and click OK. These messages will not appear when the computer is restarted after the removal instructions have been fully completed or until you run a quickscan. The messages displayed may be similar to the following:



d. If your Symantec product reports that it is unable to delete any files, take note of the file names and continue to Step 4, otherwise continue to Step 6.

4. To restart the computer in Safe mode or Safe mode with Command Prompt
Follow the instructions for your operating system.

Windows 95/98/Me
Shut down the computer and turn off the power. Wait for at least 30 seconds, and then restart the computer in Safe mode. For instructions, read the document: How to start the computer in Safe Mode.

Windows 2000
  1. Shut down the computer, and then turn off the power. Wait for at least 30 seconds, and then restart the computer
  2. When you see the black and white Starting Windows bar at the bottom of the screen, press the F8 key.
  3. In the Windows 2000 Advanced Options Menu, select Safe mode with Command Prompt, and then press Enter.

Windows XP
  1. Shut down the computer, and then turn off the power. Wait for at least 30 seconds, and then restart the computer. The computer begins processing a set of instructions known as the Basic Input/Output System (BIOS). What is displayed depends on the BIOS manufacturer. Some computers display a progress bar that refers to the word BIOS, while others may not display any indication that this process is occurring.
  2. As soon as the BIOS has finished loading, begin tapping the F8 key on your keyboard. Continue to do so until the Windows Advanced Options menu appears. If you begin tapping the F8 key too soon, some computers will display a "keyboard error" message. To avoid this, restart the computer and try again.
  3. In the Windows 2000 Advanced Options Menu, select Safe mode with Command Prompt, and then press Enter.

5. To manually delete any detected files
  1. Do one of the following:

    • Windows 2000/XP: Skip to step b.
    • Windows 95/98/Me:
      • Click Start > Run.
      • Type cmd
      • Press Enter

  2. Type cd [FILE PATH]

    Note: [FILE PATH] is the path to the file was noted in step 3d.

  3. Press Enter
  4. Type del [FILE NAME]

    Note: [FILE NAME] is the name of the file noted in step 3d.

  5. Press Enter
  6. Repeat steps b, c, and d for all files noted in step 3d.
  7. Do one of the following:

    • Windows 2000/XP: Skip to section 6.
    • Windows 95/98/Me:
      • Type exit
      • Press Enter


6. To delete the value from the registry
Important: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified subkeys only. Read the document: How to make a backup of the Windows registry.
  1. Do one of the following:

    • Windows 2000/XP: Skip to step b.
    • Windows 95/98/Me: Click Start > Run.

      Note: If you skipped steps 4 and 5, click Start > Run.

  2. Type regedit

    Then press Enter

    Note: If the registry editor fails to open the risk may have modified the registry to prevent access to the registry editor. Security Response has developed a tool to resolve this problem. Download and run this tool, and then continue with the removal.

  3. Navigate to and delete the following subkeys:

    HKEY_CURRENT_USER\Software\aurora
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\abi-1
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors\ZepMon
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SvcProc

  4. Navigate to the subkey:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

  5. In the right pane, delete any value that refers to the file detected in Step 3b.

  6. Navigate to the subkey:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

  7. In the right pane, change the value to:

    "Shell" = "Explorer.exe"

  8. Exit the Registry Editor.

  9. Restart the computer in Normal Mode.
