Can't Delete Registry Key

Discussion in 'Windows Server' started by bobneworleans, Mar 2, 2011.

  1. After two unsuccessful attempts on my own, I was finally able to
    remove McAfee Virusscan Enterprise 8.7 by following the 16 steps of
    Solution 2 in KB59996 from the McAfee KnowledgeBase. This required
    extensive work in the registry. Now, that I'm done, I'd like to clean
    up some remaining junk in the registry but there are two keys that I
    cannot select, delete, rename, export, or modify permissions: HKLM
    \Software\McAfee and HKLM\Software\Network Associates.

    When trying to select McAfee, I get this message: "McAfee cannot be
    opened. An error is preventing this key from being opened. Details:
    The system cannot find the file specified."

    When I try to delete it: "Cannot delete McAfee: Error while deleting
    key."

    When I try to export the branch I get the message: "The selected
    branch does not exist. Make sure that the correct path is given."

    When I right click on permissions: "The requested security information
    is either unavailable or can't be displayed."

    Does this indicate a null key? Is it possible to directly edit the
    underlying files that make up the registry?

    Actually, you used the wrong method to uninstall McAfee. I know, had
    the same problem with McAfee & Norton on my home system, and Symantec
    Enterprise at work.

    You should have contacted McAfee Support and they would have given you
    a link to download their McAfee Cleanup Utility, which is the ONLY way
    to FULLY remove McAfee.

    The likely issue is the a McAfee service is still running because it
    was not stopped then removed during uninstall.



    Many antivirus utilities are removed this way. Essentially it admits
    that the uninstaller that comes with the software is not very good. In
    addition Windows uninstall does not work well when any software
    publisher does not provide the needed uninstall information.

  3. Tecknomage,
    Thank you for your reply. You have made two assumptions which I
    believe are incorrect:

    1) "McAfee Cleanup Utility, which is the ONLY way to FULLY remove
    McAfee."
    The method I used came from the McAfee Corporate KnowledgeBase. One
    would reasonably presume that this is an authoritative method to fully
    remove the entire application.

    2) "a McAfee service is still running because it was not stopped then
    removed during uninstall."
    The method I used stops the following services and prevents them from
    restarting by removing the registry entries. Then the files are
    deleted:
    common management agent (CMA)
    mcavscv.dll
    anti-spyware module
    vsplugin.dll
    virus scan services
    McShield
    McTaskManager
    McAfeeEngineService
    mfevtp
    mfeavfk.sys
    mfeapfk.sys
    mfebopk.sys
    mferkdet.sys
    hidden non-PNP drivers

    So you see, the procedure is detailed and thorough. Task manager does
    not list anything that starts with mc, nor the engine. I'm pretty
    confident that no Mcafee components are running on my system.

    Now, I'm left with a minor anomaly in the registry that I'd like to
    remove just to prove that I can do it. It's really no big deal but I
    thought I'd take the opportunity to learn a little more about registry
    internals. Do you have any knowledge of how to directly manipulate
    the underlying files that make up the registry?

    Actually I didn't. I went to their (misleading) KB also. I had to
    contact McAfee Support to get the real answer/fix.

    Note that the KB article (when I looked) had no link to their cleanup
    utility, which is a hint that the KB article is old or misleading.

    Same issue with Symantec/Norton, KB articles on removal not providing
    link to cleanup tool. Maybe some day they will.

  5. I see your point.

    Can you tell me how you contacted their tech support? When I click on
    the "Chat and Email" link, it insists that I first run "McAfee Virtual
    Technician". After spending so much time ridding my computer of their
    software, I'm pretty reluctant to load any more.
