Failure on Security Essentials package installation.

    Within the last week or so I got a new update for Microsoft Security
    Essentials, an upgrade package - KB2254596, I think.

    I've got a machine with WinXP+SP3 and I am also running:
    Avast Anti-virus and Sygate Personal Firewall.

    Now, the installation of the package failed (error 0x80070643:, I believe).

    I rebooted the machine - still failed.

    Then I noticed that there was a mention somewhere about removing any
    anti-virus/anti-spyware installed. Well, I just stopped the Anti-virus and
    then stopped all the services related to it, hoping this would work.

    It didn't - now my Microsoft Security Essentials is gone (??) and obviously
    I had to activate Avast again.

    Any hint about:
    - cause?
    - solution?

    (Do I really need to uninstall Avast?)

    Thanks in advance for any help.

  2. Then I noticed that there was a mention somewhere about removing any
    There was a very prominent notice about this when you installed MSE.
    Yes. Only one (1) anti-virus application should be installed & loading at
    boot!

    Has a Norton or McAfee application ever been installed on the computer
    (e.g., a free-trial version that came preinstalled when you bought it)?

    Can I install Microsoft Security Essentials [or any other
    anti-virus/anti-spyware application] to clean up my already-infected
    computer?

    Thanks for the reply.

    No, neither Norton or McFee, ever - only Avavst.

    And now, how do I recover/reinstall MSE back? It's not showing up in Windows
    Update anymore.

  4. Uninstall Avast & reboot.

    Do a clean install of MSE & reboot.

    For further assistance, post in the appropriate MSE forum:

    Many thanks PA Bear, I'll do that.

    (Although the thought of being momentarily unprotected is a bit unsettling..)

  6. Make sure the Windows Firewall is enabled & connect via a router, if
    possible.

    NB: You can download the installer for MSE while Avast is installed then go
    offline to uninstall Avast & reboot. But you must be online to be able to
    install MSE (and Validate).
