Recommendations
Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":
- Turn off and remove unneeded services. By default, many operating systems install auxiliary services that are not critical, such as an FTP server, telnet, and a Web server. These services are avenues of attack. If they are removed, blended threats have less avenues of attack and you have fewer services to maintain through patch updates.
- If a blended threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
- Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services (for example, all Windows-based computers should have the current Service Pack installed.). Additionally, please apply any security updates that are mentioned in this writeup, in trusted Security Bulletins, or on vendor Web sites.
- Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
- Configure your email server to block or remove email that contains file attachments that are commonly used to spread viruses, such as .vbs, .bat, .exe, .pif and .scr files.
- Isolate infected computers quickly to prevent further compromising your organization. Perform a forensic analysis and restore the computers using trusted media.
- Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.
REMOVAL
The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.
- Disable System Restore (Windows Me/XP).
- Restore system files deleted by the threat.
- Use the Security Response "Tool to reset shellopencommand registry subkeys."
- Reinstall your Symantec antivirus program
- Update the virus definitions.
- Run a full system scan and delete all the files detected.
- Delete any values added to the registry.
1. To disable 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
Note: When you are completely finished with the removal procedure and are satisfied that the threat has been removed, reenable System Restore by following the instructions in the aforementioned documents.
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. To restore system files deleted by the threat
This threat attempts to delete system files that are needed to remove the threat. To restore these files, please follow the instructions below.
Note: This step may be skipped if the location of your Windows installation folder is something other than the "C:" drive.
The following documents provide general instructions on how to extract files. This information is provided for your convenience. The exact steps may vary slightly depending on the configuration of your operation system, the location of the files, and so on. For additional information, read the Help files, contact Microsoft, or refer to the following Windows documentation:
- The Microsoft Knowledge Base article: How to Extract Original Compressed Windows Files, Article ID Q129605, has detailed information for Windows 95/98/Me.
- How to extract files in Windows 98 and Windows Me.
- How to extract files using Windows 2000 or Windows NT 4.0.
- How to restore system files in Windows XP.
Important: Please ensure that you have restored the following files before proceeding:
- C:WINDOWSNotepad.exe
- C:WINDOWSSystem32Taskmgr.exe
- C:WINDOWSSystem32wuauclt1.exe
- C:WINDOWSSystem32wupdmgr.exe
- C:WINDOWSSystem32Write.exe
- C:WINDOWSSystem32egedit32.exe
- C:WINDOWSSystem32egsvr32.exe
- C:WINDOWSRegedit.exe
- C:WINDOWSSystem32 slookup.exe
- C:WINDOWSSystem32mstsc.exe
- C:WINDOWSSystem32ping.exe
This risk makes changes to the Windows registry that may prevent you from running executable files. Security Response has developed a tool to reset these values to the default settings. This tool is the easiest way to fix this. Once you have run the tool, return to this page and continue with the removal. If you cannot obtain the tool, refer to the "Additional Information" section for information on manually reversing the changes.
4. To reinstall your Symantec antivirus program
As this virus attempts to remove the files and registry subkeys that your Symantec antivirus program uses, you may need to reinstall the program. If your Symantec antivirus program is not working properly, uninstall, and then reinstall it.
5. To update 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 document: Virus Definitions (LiveUpdate).
- Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted daily.
