  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):

  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.

  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
  risk of problems that are contrary to each other.

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