Registry editing disabled

This behavior can occur if an earlier version of McAfee's VirusScan (anti- virus software) or Norton AntiVirus is being loaded from the Autoexec.bat file.

Warning This workaround may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
To resolve this issue, disable McAfee VirusScan or Norton AntiVirus. To do so, follow these steps:

1. Restart your computer, press and hold down the CTRL key until the Windows 98 Startup menu appears, and then choose Command Prompt Only.
2. At the command prompt, type edit c:\autoexec.bat, and then press ENTER.
3. Type rem, and then a space at the beginning of the line that contains Vshield.exe.
   
   If you are using Norton AntiVirus, type rem and then a space at the beginning of the line added by Norton AntiVirus.
4. Save and then close the Autoexec.bat file.
5. Restart your computer. Setup should continue.

Hi,
to make sure you´re virus free try another antivirus.
Go to:
http://www.eset.com/onlinescan/
and run the online scanner ( works with Internet Explorer only, I think ). It is pretty accurate and might find something that Avast missed.

This behavior can occur if there is an incorrect setting in the following registry entry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Common Administrative Tools

Note This registry key exists only if you upgrade your computer from Windows 98 Second Edition to Windows XP or from Windows Millennium Edition to Windows XP.

This behavior may also be caused by Norton AntiVirus 2003. For more information about this behavior and for steps that you can take to resolve the problem, visit the following Symantec Web site: http://service1.symantec.com/SUPPORT/sunset-c2002kb.nsf/9b60813077fffd2385256ee60055ac57/8b5951c9ec10830085256edf00520f16?OpenDocument&src=bar_sch_nam&seg=ag (http://service1.symantec.com/SUPPORT/sunset-c2002kb.nsf/9b60813077fffd2385256ee60055ac57/8b5951c9ec10830085256edf00520f16?OpenDocument&src=bar_sch_nam&seg=ag) Microsoft provides third-party contact information to help you find technical support. This contact information may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information. If the behavior still occurs after you take the steps to resolve the problem, remove Norton AntiVirus 2003 manually. If you cannot remove Norton AntiVirus by using the Add or Remove Programs tool, use the Rnav2003.exe utility. To remove Norton AntiVirus manually, click Add or Remove programs, click Norton Antivirus, and then clickRemove Programsin Control Panel. For information about how to download and use the Rnav2003.exe utility, visit the following Symantec Web site: http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001092114452606?Open&src=tranus_con_sl (http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001092114452606?Open&src=tranus_con_sl)

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. Run a full system scan.
4. Delete any values added to the registry.

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

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 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.
  
  If you use Norton AntiVirus 2006, Symantec AntiVirus Corporate Edition 10.0, or newer products, LiveUpdate definitions are updated daily. These products include newer technology.
  
  If you use Norton AntiVirus 2005, Symantec AntiVirus Corporate Edition 9.0, or earlier products, LiveUpdate definitions are updated weekly. The exception is major outbreaks, when definitions are updated more often.
  
  
  
• Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted daily. You should download the definitions from the Symantec Security Response Web site and manually install them.

The latest Intelligent Updater virus definitions can be obtained here: Intelligent Updater virus definitions. For detailed instructions read the document: How to update virus definition files using the Intelligent Updater.

3. To run a full system scan

1. 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.
   
   
   
2. Run a full system scan.
3. If any files are detected, follow the instructions displayed by your antivirus program.
4. Delete the autorun.inf file from writeable removable devices, if necessary.
   

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 threat 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.

4. 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. For instructions refer to the document: How to make a backup of the Windows registry.

1. Click Start > Run.
2. Type regedit
3. Click OK.
   
   Note: If the registry editor fails to open the threat 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.
   
   
4. Navigate to the following registry subkeys:
   
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
   HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
   HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows\"load"
   
   
5. In the right pane, delete any values associated with the worm.
   
   
   
6. Exit the Registry Editor.

Hello hawk893

Are you logged into a Windows profile w/ Administrator privileges?

If not, change your user profile rights to Administrator (from another Administrator profile).

If the problem persists, enter Safe Mode and try enabling and disabling NAV (Norton Antivirus) from there.

If the problem still persists, you may have picked up a virus that disabled your AV software. You can go HERE if you like to perform an online AV scan. There are other sites as well that will do this for you. Just perform a search engine search on "Online AV Scan".

If you need assistance w/ any of these recommendations, just let me know. I'll be happy to provide detailed instructions for you.


Please, let us know if this response was helpful for you or, of course, if you have more questions, etc. on this topic.

Thank you

Question/Issue:
When you install Symantec AntiVirus or Symantec Client Security, you see the error message "1920 Service Defwatch failed to start. Verify that you have sufficient privileges to start system services."


Solution:
This problem has more than one cause, so more than one solution is provided. To fix the problem, try each of the following solutions in the order that they appear.

Confirm that you have the correct rights and permissions
The most common cause of this problem is incorrect rights or permissions. Make sure that you have Local Administrator rights to the target computer. Confirm that no restrictions on the Local Administrator or Domain Administrator accounts exist.. Follow the directions in the document Troubleshooting Symantec AntiVirus Corporate Edition installations: Checking rights and permissions.


Confirm that the Defwatch service has the correct settings
This problem can happen when the Defwatch service account has incorrect settings. Make sure that the Defwatch service is set to log on as the Local System account. Confirm that the service is allowed to interact with the desktop.

To confirm the Defwatch service settings

1. On the Windows taskbar, click Start > Run.
2. In the Open box, type services.msc and then click OK.
3. Do one of the following, depending on your program version:
   • For Symantec AntiVirus 10.x, right-click the Symantec AntiVirus Definition Watcher entry.
   • For Symantec AntiVirus 9.x and earlier, right-click the Defwatch entry.
4. Click Properties.
5. On the Log On tab, confirm that the Local System Account is selected and that "Allow service to interact with desktop" is checked.
6. Click OK.

Look for a Program file at the root of the OS drive.
If McAfee antivirus 4.03 or 4.5 was installed on the computer, look for a file that is named "Program" at the root of the OS drive. If the file exists, delete it.


Delete leftover registry keys from a previous version of Symantec or Norton AntiVirus Corporate Edition
Leftover registry keys from a previous version of Symantec or Norton AntiVirus Corporate Edition can cause this problem. Delete the registry keys and then install Symantec AntiVirus again.

WARNING: In the next steps you will edit the Windows registry. Back up the registry before you make any changes to it, because incorrect changes to the registry can result in permanent data loss or corrupted files. Modify only the registry keys that are specified.
For instructions, see How to back up the Windows registry.


To delete the registry key

1. On the Windows taskbar, click Start > Run.
2. In the Open box, type the following text:
   
   regedit
   
   
3. Click OK.
4. In the Windows Registry Editor, in the left pane, click My Computer.
5. On the Edit menu, click Find.
6. In the Find what box, type the following text:
   
   VirusProtect6
   
   Delete all keys and values that contain this string.
7. Go to and delete the following key:
   
   HKEY_LOCAL_MACHINE\SOFTWARE\INTEL\DLLUsage\VP6
   
   
8. Exit the Windows Registry Editor.

If the problem persists, manually remove the previously-installed version of Symantec AntiVirus. To find directions for your product version, read Manual uninstallation documents for Symantec Client Security products
