CAUTION: Once a computer has been attacked by W32.Goner.A@mm, it is possible that the system security has been compromised. The worm deletes common antivirus and firewall products and requires that such products be reinstalled.

NOTE: You must have administrative rights to run this tool on Windows NT4.

Download the FixGoner.exe file from:

http://securityresponse.symantec.com/avcenter/FixGoner.exe

Save the file to a convenient location, such as your download folder or the Windows desktop (or removable media that is known to be uninfected, if possible).
To check the authenticity of the digital signature, refer to the section The digital signature.
Close all running programs before running the tool.
If you are on a network or you have a full-time connection to the Internet, disconnect the computer from the network and the Internet.
If you are running Windows Me or XP, then disable System Restore. Please refer to the section System Restore option in Windows Me/XP for additional details.

NOTE: If you are running Windows Me/XP, we strongly recommend that you do not skip this step.

Double-click the FixGoner.exe file to start the removal tool.
Click Start to begin the process, and then allow the tool to run.
Restart the computer.
Run the removal tool again to ensure that the system is clean.
If you are running Windows Me/XP, then re-enable System Restore.
Run LiveUpdate to make sure that you are using the most current virus definitions.

CAUTION: If the worm has successfully deleted the target Norton AntiVirus files, you must uninstall and then reinstall Norton AntiVirus before you can start Norton AntiVirus or run LiveUpdate. If Norton AntiVirus was installed as part of another Symantec program, such as System Works or Norton Internet Security, you must uninstall and reinstall those as well. Read the instructions in the section How to uninstall and reinstall your Symantec software before you continue.When finished, return to this section and complete the removal procedure.

NOTE: The removal procedure might be unsuccessful if Windows Me/XP System Restore is not disabled as previously directed because Windows prevents System Restore from being modified by outside programs. Because of this, the removal tool might fail.

When the tool has finished running, you will see a message indicating whether the computer was infected by the W32.Goner.A@mm. In the case of a removal of the worm, the program displays the following results:


The total number of the scanned files.
The number of deleted files.
The number of viral processes terminated.
The number of registry values deleted.

The digital signature
FixGoner.exe is digitally signed. Symantec recommends that you only use copies of FixGoner.exe that have been downloaded directly from the Symantec Security Response download site. To check the authenticity of the digital signature, follow these steps:
Go to http://www.wmsoftware.com/free.htm
Download and save the chktrust.exe file to the same folder where you saved FixGoner.exe (for example, C:\Downloads).
Depending on your operating system, do one of the following:
Click Start, point to Programs, and click MS-DOS Prompt.
Click Start, point to Programs, click Accessories, and then click Command Prompt.
Change to the folder where FixGoner.exe and Chktrust.exe are stored, and then type:

chktrust -i FixGoner.exe

For example, if you saved the file to the C:\Downloads folder, you would enter the following commands:

cdcd downloads
chktrust -i FixGoner.exe

Press Enter after typing each command. If the digital signature is valid, you will see the following:

System Restore option in Windows Me/XP
Windows Me and Windows XP users should temporarily turn off System Restore. This feature, which is enabled by default, is used by Windows Me/XP to restore files on your computer in case they become damaged. When a computer is infected with a virus, worm, or Trojan, it is possible that the virus, worm, or Trojan could be backed up by System Restore. By default, Windows prevents System Restore from being modified by outside programs. As a result, there is the possibility that you could accidentally restore an infected file, or that on-line scanners would detect the threat in that location. For instructions on how to turn off System Restore, read your Windows documentation or one of the following articles:
How to disable or enable Windows Me System Restore.
How to disable or enable Windows XP System Restore.
For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article Anti-Virus Tools Cannot Clean Infected Files in the _Restore Folder, Article ID: Q263455.

NOTES:
There are no spaces in the command a:\FixGoner.exe
If you are using Windows Me, and the System Restore remains enabled, you will see a warning message. You can choose to run the removal tool with the System Restore option enabled or exit the removal tool.

Click Start to begin the process, and then allow the tool to run.
