2. Creates the following registry subkeys:
   
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes\EAB51286E37F57342B8CFF6E6B117052
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{8E039B25-ED8E-433B-A5C1-DF9795FAB936}
   HKEY_USERS\Software\Microsoft\Installer\Features\52B930E8E8DEB3345A1CFD7959AF9B63
   HKEY_USERS\Software\Microsoft\Installer\Products\52B930E8E8DEB3345A1CFD7959AF9B63
   HKEY_USERS\Software\Microsoft\Installer\UpgradeCodes\EAB51286E37F57342B8CFF6E6B1170
   
   
3. Captures the URLs of Web sites visited on the compromised computer by listening on TCP port 10003. The risk consists of a client component and a server component, and this action is performed by the client.
   
   
4. Sends any information it gathers to the server component of the risk, which can also be used to perform the following actions:
   
   
   • Configure the client component
   • Send a copy of the client component to a local or remote location on a network
   • Send messages to users on the compromised computer
   • End Web browser processes
   • Change the TCP port on which the server component communicates with the client (The default value is TCP port 23.)
     
     Note: It is possible to access a command window for the client component by pressing the key combination Ctrl+Alt+F7. Users can end the client and server processes using this command
     window, but will have to enter a password first, which can be found in the risk's help file.

REMOVAL

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

1. Update the definitions.
2. Run a full system scan.
3. Delete any values added to the registry.
   

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 run the scan

1. Start your Symantec antivirus program, and then run a full system scan.
   
2. 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.
       
       
   • 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. The messages displayed may be similar to the following:

Title: [FILE PATH]
Message body: Windows cannot find [FILE NAME]. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

3. 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. Click Start > Run.
2. Type regedit
   
   Then click OK.
   
   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 subkeys:
   
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes\EAB51286E37F57342B8CFF6E6B117052
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{8E039B25-ED8E-433B-A5C1-DF9795FAB936}
   HKEY_USERS\Software\Microsoft\Installer\Features\52B930E8E8DEB3345A1CFD7959AF9B63
   HKEY_USERS\Software\Microsoft\Installer\Products\52B930E8E8DEB3345A1CFD7959AF9B63
   HKEY_USERS\Software\Microsoft\Installer\UpgradeCodes\EAB51286E37F57342B8CFF6E6B1170
   
   
4. Exit the Registry Editor.
