＜這一段是大綱＞
The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.

１．Disable System Restore (Windows Me/XP).

２．Update the virus definitions.

３．Restart the computer in Safe mode or VGA mode.

４．Run a full system scan and delete all the files detected as Backdoor.Trojan.

５．Reverse the changes made to the Windows registry.

６．Windows 95/98/Me only: Remove any references to the infected files that have been added to the Win.ini and System.ini files.

＜這一段是細節＞

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

Note: The procedure described in this document is complex and assumes that you are familiar with basic Windows and DOS procedures. If you are not, then we suggest that you obtain the services of a qualified computer consultant.

1. Disabling System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

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 turn off or turn on Windows XP System Restore"

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article, "Antivirus Tools Cannot Clean Infected Files in the _Restore Folder," Article ID: Q263455.

2. Updating the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:
Running LiveUpdate, which is the easiest way to obtain virus definitions: These virus definitions are posted to the LiveUpdate servers once each week (usually on Wednesdays), unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, refer to the Virus Definitions (LiveUpdate).
Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted on U.S. business days (Monday through Friday). You should download the definitions from the Symantec Security Response Web site and manually install them. To determine whether definitions for this threat are available by the Intelligent Updater, refer to the Virus Definitions (Intelligent Updater).

The Intelligent Updater virus definitions are available: Read "How to update virus definition files using the Intelligent Updater" for detailed instructions.

3. Restarting the computer in Safe mode or VGA mode
Shut down the computer and turn off the power. Wait for at least 30 seconds, and then restart the computer in Safe mode or VGA mode.
For Windows 95, 98, Me, 2000, or XP users, restart the computer in Safe mode. For instructions, read the document, "How to start the computer in Safe Mode."
For Windows NT 4 users, restart the computer in VGA mode.


4. Scanning for and deleting the infected files
Start your Symantec antivirus program and make sure that it is configured to scan all the files.
For Norton AntiVirus consumer products: Read the document, "How to configure Norton AntiVirus to scan all files."
For Symantec AntiVirus Enterprise products: Read the document, "How to verify that a Symantec Corporate antivirus product is set to scan all files."
Run a full system scan.
If any files are detected as infected with Backdoor.Trojan, write down the path and file names, and then click Delete.

Note: If your Symantec antivirus product reports that it cannot delete an infected file, shut down the computer, turn off the power, and then wait 30 seconds. Restart the computer in Safe mode (Windows 95/98/Me/2000/XP) or VGA mode (Windows NT 4), and then run the scan again.

For instructions on restarting the computer in Safe mode, read the document, "How to start the computer in Safe Mode."


5. Reversing the changes that were made to the registry

CAUTION: 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.

Click Start, and then click Run. (The Run dialog box appears.)
Type regedit

Then click OK. (The Registry Editor opens.)


Navigate to the key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run


Refer to the list of infected files that you created while following the instructions in step c of the previous section, "Scanning for and deleting the infected files."

In the right pane, look at the entries in the Name and Data columns. If you find an entry that refers to a file that was detected as infected, select the entry, press Delete, and then click Yes to confirm.


Do one of the following:
Windows NT/2000/XP: Skip to step g.
Windows 95/98/Me: Navigate to the key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
RunServices


Refer to the list of infected files that you created while following the instructions in the previous section. In the right pane, look at the entries in the Name and Data columns. If you find an entry that refers to a file that was detected as infected, select the entry, press Delete, and then click Yes to confirm.


Exit the Registry Editor.


6. Removing the references to the infected files from the Win.ini and System.ini files
If you are running Windows 95/98/Me, follow these steps:

The function you perform depends on your operating system:
Windows 95/98: Go to step B.
Windows Me: If you are running Windows Me, the Windows Me file-protection process may have made a backup copy of the Win.ini file that you need to edit. If this backup copy exists, it will be in the C:\Windows\Recent folder. Symantec recommends that you delete this file before continuing with the steps in this section. To do this:
Start Windows Explorer.
Browse to and select the C:\Windows\Recent folder.
In the right pane, select the Win.ini file and delete it. The Win.ini file will be regenerated when you save your changes to it in step F.


Click Start, and then click Run.
Type the following, and then click OK:

edit c:\windows\win.ini

The MS-DOS Editor opens.

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

CAUTION: The following steps instruct you to remove text from the load= and run= lines of the Win.ini file. If you are using older programs, they may be loading at startup from one of these lines. The Trojan can add lines, such as load=c:\windows\temp\pkg2350.exe or run=hpfsched <blank spaces> msrexe.exe. (In this example, hpfsched is a legitimate program, but msrexe.exe is part of the Trojan.)

If you are sure that the text contained in these lines is for programs that you normally use, then we suggest that you do not remove it. If you are not sure, but the text does not refer to the file names you wrote down earlier, then you can prevent the lines from loading by placing a semicolon in the first character position of the line.

For example:

; run=accounts.exe


Locate the load= line within the [windows] section of the Win.ini file; it is usually located near the top of the file.
Position the cursor immediately to the right of the equal (=) sign.
Press Shift+End to select all the text to the right of the equal sign, and then press Delete.
Repeat the steps in sections 3 to 5 for the run= line, which is usually beneath the load= line.
Click File, click Exit, and then click Yes when you are prompted to save the changes.
Click Start, and then click Run.
Type the following, and then click OK:

edit c:\windows\system.ini

The MS-DOS Editor opens.

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


Locate the shell=explorer.exe line within the [boot] section of the System.ini file; it is usually located near the top of the file.
Position the cursor immediately to the right of explorer.exe.
Press Shift+End to select all the text to the right of explorer.exe, and then press Delete.

NOTE: Some computers may have an entry other than explorer.exe after shell=. If this is the case and you are running an alternate Windows shell, then change this line to shell=explorer.exe for now. You can change it back to your alternate shell after you have finished this procedure.


Click File, click Exit, and then click Yes when you are prompted to save the changes.

This completes the removal part of the process. Even though you did so previously, start your Symantec antivirus product and run another full system scan. Delete any files that are found to be infected with Backdoor.Trojan. When the scan is finished, restart the computer.




Additional information:

Norton Internet Security/Norton Internet Protection users
If you are using Norton Internet Security or Norton Internet Protection, the name that the Trojan Block rule uses to prevent the Trojan from being downloaded to your computer is different than the name that Norton AntiVirus uses to detect the same threat, if it was actually run on your computer or received in email.

Norton Internet Security/Norton Internet Protection will block Backdoor.Trojan from being downloaded onto your computer, using one of the following Block Rules: Hack A Tack, Girlfriend, Filenail, DeepThroat, Coma, Bugs, or Backdoor/SubSeven.
