Follow the instructions given. Be sure to change these settings back after you are done.

It is not generally necessary to remove registry entries if reinstalling ZoneAlarm Pro. However, should you choose to do so, the following registry entries aree associated with ZoneAlarm Pro:

Important Advisory: Deleting registry entries incorrectly may cause serious problems to your operating system (OS) which may necessitate the need to reinstall the OS. Please make sure you are able to perform these deletions correctly before you decide to edit the entries.

For information about how to edit the registry in Windows, type "regedit.exe" from a command prompt. Click "Help," then "Help Topic." Click "Changing Keys and Values."

Note that you should back up the registry before you edit it.

To enter the registry, go to Start/Run and type: "regedit." Use Control-F to find and F3 to Find Next.

  • Registry Entries:

    - Key: HKEY_LOCAL_MACHINE\SOFTWARE\Zone Labs and all its subkeys and values.
    - Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\ZoneAlarm ZoneAlarm Pro

  • These two registry keys, and all their subkeys, denote the TrueVector service and the TrueVector device driver:

    - Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\vsmon
    - Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\vsdatant

  • This registry key and its subkeys denote ZoneAlarm Pro's alert logging service:

    - Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\minilog

  • This is a database that contains a long list of values, but only these values are related to ZoneAlarm Pro and TrueVector:

    - Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\SharedDLLs
    - Values:

    C:\Program Files\Zone Labs\ZoneAlarm\tutorwiz.dll
    C:\WINNT\System32\Zone Labs\html.tdr
    C:\WINNT\System32\Zone Labs\vsdb.dll
    C:\WINNT\System32\Zone Labs\minilog.exe
    C:\WINNT\System32\Zone Labs\vsmon.exe
    C:\WINNT\System32\Zone Labs\vsruledb.dll

  • For each user who has run ZoneAlarm Pro, there are registry keys in

    - Key: HKEY_CURRENT_USER\Software\Zone Labs

  • The following keys allow the user to modify the sound that is played when there is an alert through use of the Control Panel Sounds applet:

    - Key: HKEY_CURRENT_USER\AppEvents\EventLabels\InternetAlert
    - Key: HKEY_CURRENT_USER\AppEvents\Schemes\Apps\.Default\InternetAlert\.current

  • The following keys are related to ZoneAlarm Pro's MailSafe Feature:


  • There is a value for the extension of every attachment that ZoneAlarm Pro quarantines (.vbs, for example). To find the values and keys to delete:

    1) Click on HKEY_CLASSES_ROOT
    2) Press F3.
    3) Type "zamailsafe" in the search field (no quotes).
    4) Press F3 to find the next value. An example of the value you will see (on the right-hand side of the window) would be: ZAMailSafeExt: REG_SZ: {renamed extension - zl9, for example).
    5) Delete the value. Press "OK" at the prompt.
    6) Repeat until there are no more values like the example above. ZoneAlarm Pro quarantines 37 extensions by default. However, any additional extentions you may have chosen to quarantine will also be listed in the registry.

  • There is also a registry key for the extension of every attachment renamed by ZoneAlarm Pro. The names of the keys will range from .zl0 to .zly. If you wish, you can follow the instructions above to find the values associated with these keys. Delete the entire key which contains these values.
