    Technical description:

    Removal instructions:

    Because W32.Badtrans.13312@mm affects different operating systems in different ways, how you remove this worm depends on your operating system. Follow the instructions in the order given.

    To remove the worm:

    1. Run LiveUpdate to make sure that you have the most recent virus definitions.
    2. Start Norton AntiVirus (NAV), and run a full system scan, making sure that NAV is set to scan all files.

    If you are running Windows NT/2000 and NAV was able to delete all the infected files, you are finished.
    If NAV was not able to delete all files that it detected as infected, go on to the next section and see the instructions for your operating system.

    To edit the registry:

    CAUTION: We strongly recommend that you back up the system registry before making any changes. Incorrect changes to the registry could result in permanent data loss or corrupted files. Please make sure you modify only the keys specified. Please see the document How to back up the Windows registry before proceeding. This document is available from the Symantec Fax-on-Demand system. In the U.S. and Canada, call (541) 984-2490, select option 2, and then request document 927002.
    1. Click Start, and click Run. The Run dialog box appears.
    2. Type regedit and then click OK. The Registry Editor opens.
    3. Navigate to the key

    HKEY_LOCAL_MACHINE\Software\Microsoft\
    Windows\CurrentVersion\RunOnce

    4. In the right pane, delete the value

    Kernel32 KERN32.EXE

    5. Navigate to the key

    HKEY_CURRENT_USER\Software\Microsoft\
    Windows NT\CurrentVersion\Windows

    6. In the right pane, delete the value

    run <path>\Inetd.exe

    7. Exit the Registry Editor.
    8. Restart the computer.
    9. Run the scan again, and delete any files detected as W32.Badtrans.13312@mm. This completes the removal procedure for users of Windows NT/2000.

    To edit the Win.ini file:
    If you are running Windows 95/98/Me, you must also do the following:
    1. Click Start, and click Run.
    2. Type the following and then click OK:

    edit c:\windows\win.ini

    NOTE: If you installed Windows in a different location, make the appropriate substitution.

    3. In the [windows] section, locate the run= line. It will look similar to the following:

    run=c:\windows\inetd.exe

    4. Remove the text to the right of the = sign, so that the line now reads

    run=

    5. Save your changes, and exit the MS-DOS Editor.
