I can't turn on Windows Defender. Is this a common problem? A way to start the program or remove and reload?

What AV program do you use? (Not to mention your operating system). If you have MSE, or an installed security suite, it will automatically stop WD as it has its own version and runs two programs of this type at the same time causes conflicts.

This forum is for the site's comments and your question should be asked in an appropriate forum if this does not answer your question.

    Hello

    Are you running MSE or other antivirus/security programs stop Windows Defender from
    running? Whether Windows Defender is blocked from running by them. McAfee, AVG, and
    others do this. MSE includes Windows Defender features in it run
    separately would be redundant.

    McAfee blocks Windows Defender, as well as other programs such as AVG antivirus/security and others.

    If you want to use another thing don't forget to uninstall McAfee and then run the McAfee removal tool then

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

    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.

    I tried finding the Windows Defender application, but can not.  Any ideas how I can find and put in operation?  I stopped using another product of virus protection, and now I need to get this sort that I do not know if windows 8 is as safe as it should be.

    Hello

    You will need to uninstall Norton... You'd better go to their website for their removal tool. Simply uninstalling was reported to leave artifacts that still block Windows Defender.

    In fact, Norton can offer better protection, but of how much better, you could try a search for comments and/or a comparison... Norton will probably slow down your machine more than the Defender, but I have not tried lately to say how much.

    Most likely the Office 365 is a trial provided by the manufacturer of the computer for which you will have to pay for eventually... just a guess but.

  • Whenever I try to change the settings for startup from the Control Panel, a pop up tells me that I need to activate Windows Defender and open

    I installed Microsoft Security Essentials today and I'm trying to edit startup programs.

    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.

    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; basically to have something very similar to the built-in Defender, and both running at a time will be your performance level and create the risk of problems that are contrary to the other.
