  original title: My Windows Defender

  My Windows Defender will not stay on, even though I have a scan scheduled @ 02:00 every day. I do not understand why the Defender stops, and I get a warning telling me it's off. It analyzes every day @ 02:00, and I manually do a quick scan when I see the warning icon. Help!
  Thank you for your help.

• Windows Defender will not be updated

  I am experiencing strange shift of internet and I think it's because Windows Defender won't be able to update. I am running Vista x 64 final. I recently started to receive a new error every time I start my computer, something to the effect of Windows Defender service is unable to start. If I try to start it manually, I got the error: 0 x 80070003: the system cannot find the path specified.

  Normally I wouldn't complain about windows Defender does not because I have my own solutions, but I believe that it is still problematic within my system. Every half hour or so, my firewall warns me to say that something in a temporary folder called mpistub.exe or something is trying to access the internet. I found this exe is a windows update, so I allow it through. Now, I believe that because the service cannot start, the update is impossible to apply and continues to go to the internet to try to get a shift to internet update, causing news for my pc everything.

  Someone knows something like that? I would like to reinstall windows Defender so that it can update itself and let my only internet. And I don't mean simply turning on or off; I can't do this if the service does not start. Oh and I tried to restore to an earlier date, it is not far enough.

  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.

• Windows Defender will not activate in Windows Vista

  I use windows vista and after I bought Norton 360 and put it on my HP laptop... whenever I wish my PC it seems there is a problem with windows security. When I open my windows Defender would emerge but let me enable it by running the update for it.  Now it lights up at all... I get a message that windows security is unable to activate windows defender on please try again later... more later she just said and did the same thing and will not let me install another version of windows defender... OH one thing... after having installed Norton on this laptop as well as my other more old or my CD/DVD burner drivers works not at all... will not read a disc at all... what happens?

  You should never have 2 versions on any antivirus installed on your computer, or 2 different AVs installed.

  It will cause problems.

  I suggest that solve you your Norton anti-virus to address any problem of CD.

  Contact the Norton Support.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  If you have Microsoft Security Essentials, AVG, McAfee, Norton, etc. installed, they have a conflict with Windows Defender, or turn it off.

  Microsoft Security Essentials has its own integrated version of the defender and should automatically disable the version of Vista in Windows Defender.

  If it's not:

  Turn Windows Defender on or off the information on the link above of Microsoft.

  Hope the above explains the common compatibility issues with Windows Defender and other security programs.

• Clean reinstalled Vista. Windows Defender will not be open and turn on. Can I uninstall and reinstall WD?

  I use Windows Security Essentials OK, but Windows Defender is DISABLED and cannot be turned on. What should do?

  I use Windows Security Essentials OK, but Windows Defender is DISABLED and cannot be turned on. What should do?

  Windows Defender is part of the Vista operating system. It cannot be uninstalled, nor can you install another fresh copy in the system. This Windows Defender lives and dies with the operating system.

  It is called Microsoft Security Essentials, not Windows Security Essentials.

  MSE (Microsoft Security Essentilas) is supposed to close Windows Defender.
  This is because MSE has his own Defender. Run 2 defenders in the same machine allows to create conflicts.

  Therefore, it is normal to find widows Defender NOT enabled if you installed MSE.

  You don't have to do a thing. So be.

  If you want Windows Defender turned on because you want to access with the startup programs, here's another way without using Windows Defender...

  Start button in the search box, type msconfig... Enter... click on start up tab... Here is the list of your startup programs.

• Windows Defender will not stay.

  Recently, I realized that I didn't have Windows Defender on my new computer, and it was on my old.  So I downloaded.  Now, every day I put on (if I remember) which I didn't do before.  I have Windows XP and AVG (free) for protection.  I don't have Vista.  When I was reading the other posts, most of them had to do with Vista and McAfee.  I need help for my computer.  How can I keep enabled?  I went to tools, properties, etc... and he said: it's on, but then the next day, I have to restart.

  I recommend that you leave Windows Defender installed, this way if you have any questions, it's a more resources at your disposal. I use AVG and Yes AVG disables Windows Defender, however, I recently received a very bad virus and after working hours to clean and remove the files manually, Windows Defender has found the final key file.  I used AVG and Norton both ran own scans. Finally, I ran Windows Defender and it finds a file viral severe level 1. After that Windows Defender fixed and the content of the file, everything is 100% new.

  She is already here, just keep it as a safety net :-)
