  How can I turn off "Windows defender"?

  Hello Steve,.

  Welcome! Thanks for posting in the HP Support forum.

  Usually, if you install the 3rd AV software part (for example, Kaspersky, Norton, McAfee, Tredn Micro...) it allows to disable Windows Defender. However you can do it manually.

  Several options are described here

• Something in my system turns off Windows Defender.

  Something in my system turns off Windows Defender once from time to time, and I have to keep back on.

  I am running Windows XP and security programs I use are Microsoft Security Essentials, Microsoft Malicious Software Removal Tool,
  Spybot Search and Destroy and Ad-Aware from Lavasoft.
  I normally have all running at the same time, and with Spybot SD have also resident 'SD Helper' and 'Tea Timer"active.

  Any ideas what could cause this problem?

  Hello

  As you use Microsoft Security Essentials, the reason for this is that MSE has its own version of the Defender as part of its program.

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

  Read this information about it:

  "Windows Defender and Microsoft Security Essentials on Windows 7, Windows Vista and Windows XP.

  http://answers.Microsoft.com/en-us/protect/Forum/protect_start/Windows-Defender-and-Microsoft-Security-Essentials/5309cb8d-02e1-40E8-974f-0dcedb9ab9fd

  Q: I have to manually disable or uninstall Windows Defender, if I use Microsoft Security Essentials?
  If Microsoft Security Essentials does not automatically uninstall Windows Defender on XP, you must manually uninstall Windows Defender through Control Panel of configuration/Add / Remove programs.

  See you soon.
