W32.Entangle.Worm - Removal

To remove W32.Entangle.Worm, scan with NAV and delete files that are detected as W32.Entangle.Worm. If you are running Windows 95/98/Me, then remove the entry that the worm left in the System.ini file.

See the following detailed instructions.

To delete files that are detected as W32.Entangle.Worm:

1. Obtain the most recent virus definitions. There are two ways to do this:
   • Run LiveUpdate. LiveUpdate is the easiest way to obtain virus definitions. These virus definitions have undergone full quality assurance testing by Symantec Security Response and are posted to the LiveUpdate servers one time each week (usually Wednesdays) unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, look at the Virus Definitions (LiveUpdate) line at the top of this write-up.
   • Download the definitions using the Intelligent Updater. Intelligent Updater virus definitions have undergone full quality assurance testing by Symantec Security Response. They are posted on U.S. business days (Monday through Friday). They must be downloaded from the Symantec Security Response Web site and installed manually. To determine whether definitions for this threat are available by the Intelligent Updater, look at the Virus Definitions (Intelligent Updater) line at the top of this write-up.
     
     Intelligent Updater virus definitions are available here. For detailed instructions on how to download and install the Intelligent Updater virus definitions from the Symantec Security Response Web site, click here.
     
2. Start Norton AntiVirus (NAV), and make sure that NAV is configured to scan all files. For instructions on how to do this, read the document How to configure Norton AntiVirus to scan all files.
3. Run a full system scan.
4. Delete all files that are detected as W32.Entangle.Worm.

To edit System.ini:

NOTES:

• Follow the steps in this section only if you are running Windows 95/98/Me.
• For Windows Me users only: Due to the file-protection process in Windows Me, a backup copy of the file that you are about to edit exists in the C:\Windows\Recent folder. Symantec recommends that you delete this file before you continue with the steps in this section. To do this using Windows Explorer, go to C:\Windows\Recent, and in the right pane select the Win.ini file and delete it. It will be regenerated as a copy of the file that you are about to edit when you save your changes to that file.

1. Click Start, and then click Run.
2. Type the following:
   
   edit c:\windows\system.ini
   
   NOTE: If Windows is installed in a different location, then make the appropriate path substitution.
   
3. Click OK. The MS-DOS Editor opens.
   
4. In the [boot] section of the file, look for a line similar to the following:
   
   shell = explorer.exe <worm name from list in technical description>
   
   For example:
   shell = explorer.exe desk.exe
   
5. If the line exists, then select the entry after explorer.exe and then press Delete. When you have finished, only shell = explorer.exe should remain.
6. Click File, and then click Save.
7. Click File, and then click Exit.
