You are running Microsoft Security Essentials, AVG, Norton or McAfee?
If you run one of those, she didn't have Defender. It's
good, not bad. Not only is there potential conflict, but there is no
reason to have both; essentially, they have something very similar
for the Defender integrated and running both at once will hurt your
performance and create the risk of problems that are contrary to each
others.

    Hello

    If you use Norton, AVG, Avira, Microsoft Security Essentials, McAfee, etc. the default action is for Windows Defender must be disabled, that these AntiVirus programs have their own Antispyware Applications.

    There is nothing to worry.

    Using both programs at the same time can cause system conflicts, etc.

    If you are using one of the above AntiVirus programs, this Information from David O - Support Engineer shows you how to manually enable Windows Defender (disregard information from uninstalling; not possible in Vista):

    "Go to start, Control Panel, Administrative Tools, Services. Look for Windows Defender.

    Right click and select Properties , ensure that Startup Type is automatic.

    Once modified, click apply and OK.

    Quit and restart your computer. Check the back take the same path to confirm that Windows Defender has started"

    If you want to have additional protection against malware using the version FREE of Malwarebytes AntiMalware:

    Yes, that's why. Microsoft Security Essentials, AVG, Norton, and
    McAfee all turn them off Defender. It's good, not bad. Not only is at - it
    potential conflict, but there is no reason to have both. they are all
    basically have something very similar to the built-in Defender.
    and both running at once will be your performance level and create the

    It is not correct that you can't remove it without defender. Use
    MSCONFIG, which is part of Windows.

    =================================

    Here's what I use and recommend: (these are all free and very effective versions.)

    Avast and Prevx proved extremely reliable and compatible with all I have
    launched on them. Microsoft Security Essentials and Prevx have also proven to be very
    reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

    Avast Home free - stop any shields is not necessary except leaving Standard, Web, and
    Operation of the network.

    Prevx - Home - free

    Windows Firewall

    Windows Defender (is not necessary if you use MSE)

    Protected IE - mode

    IE 8 - SmartScreen filter WE (IE 7 phishing filter)

    I also IE always start with asset if filter InPrivate IE 8.
    (It may temporarily turn off with the little icon to the left of the + bottom
    right of IE)

    Two versions of Avast are available 5.x and 4.8 x

    Avast - home - free - 5.x stop shields you do not use (except files, Web, network, &)
    Shields of behavior) - double click on the icon in the Notification area - real time Orange - click on the
    Shield that you want to stop - STOP. To stop the Orange icon to show an error indicator-
    Click on the Orange icon - top right - settings - click on the status bar - uncheck shields you
    disabled - click OK
    http://www.avast.com/free-antivirus-download

    Avast 4.8 x - home - free - stop shields, you don't need except leaving Standard, Web,.
    and the network running. (Double-click the blue icon - look OK. - upper left - Shields details
    Finish those you don't use).
    http://www.avast.com/free-antivirus-download#TAB4

    Or use Microsoft Security Essentials - free
    http://www.Microsoft.com/Security_Essentials/

    Prevx works well alongside MSE or Avast

    Prevx - home - free small, fast, exceptional protection CLOUD, working with other security
    programs. It is a single scanner, VERY EFFICIENT, if it finds something come back here
    or use Google to see how to remove.
    http://www.prevx.com/   <-->
    http://info.prevx.com/downloadcsi.asp  <-->

    PCmag - Prevx - Editor's choice
    http://www.PCMag.com/Article2/0, 2817,2346862,00.asp

    Also get Malwarebytes - free - use as scanner only. If you ever think malware and that
    would be unusual with Avast and occasional Prevx running with the exception of a low level cookie
    (not much), to UPDATE and then run it as a scanner. I have a lot of scanners and they
    never find anything of note that I started to use this configuration.
