When Dialer.WildJP is activated, it performs the following actions:
  1. Copies itself as these files:
    • %Program Files%\COMSOFT\DIALERS\WILD4_JP\WILD4_JP.EXE
    • %System%\WILD4_JP-UNINSTALL.EXE


      Notes:
    • %System% is a variable. The dialer locates the System folder and copies itself to that location. By default, this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).
    • %ProgramFiles% is a variable that refers to the path to the program files folder. By default, this is C:\Program Files.

The following instructions pertain to all Symantec antivirus products that support Security Risk detection.

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

1. Updating the definitions
To obtain the most recent definitions, start your Symantec program and run LiveUpdate.

2. To close modem connections
This risk uses available modems to create an Internet connection, sometimes without any visible signs. In order to successfully remove this threat, ensure that all modem-based Internet connections are disconnected before proceeding. For instructions on how to do this, consult the appropriate Internet service provider, computer manufacturer, or operating system documentation.

3. Uninstalling the Adware
  1. Do one of the following:
    • On the Windows 98 taskbar:
      1. Click Start > Settings > Control Panel.
      2. In the Control Panel window, double-click Add/Remove Programs.

    • On the Windows Me taskbar:
      1. Click Start > Settings > Control Panel.
      2. In the Control Panel window, double-click Add/Remove Programs.
        If you do not see the Add/Remove Programs icon, click "...view all Control Panel options."

    • On the Windows 2000 taskbar:
      By default, Windows 2000 is set up the same as Windows 98. In that case, follow the instructions for Windows 98. Otherwise, click Start, point to Settings, point to Control Panel, and then click Add/Remove Programs.

3. Scanning for and deleting the files
  1. Start your Symantec antivirus program, and then run a full system scan.
  2. If any files are detected as Dialer.WildJP, click Delete.


    Notes:
  • If your Symantec antivirus product reports that it cannot delete a detected file, write down the path and file name. Then use Windows Explorer to locate and delete the file.
  • If you ran the Add/Remove programs applet as described in the previous section, all the files may have been removed, and therefore none will be detected.
