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

1. To update 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. To record the path to the ieloader.dll file

1. Start your Symantec antivirus program and run a full system scan.
2. If any files are detected as Dialer.Coder, record the path to the file. Do not try to delete it at this time.
   

4. To unregister the ieloader.dll file

1. Click Start > Run.
2. Type, or copy and paste, the following text:
   
   regsvr32 /u <pathieloader.dll>
   
   then click OK.
   
   For example, if the ieloader.dll was detected in the C:Windows folder, you would type:

WARNING: 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 keys only. Read the document, "How to make a backup of the Windows registry," for instructions.
