  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!

• Unable to use wireless internet. In addition, my windows update will not be installed.

  Original title: extended error code = Oxfof4

  I have a couple of different symptoms. My laptop acts like it doesn't even have wireless capabilities although the exact model the same sitting next to her was a strong wireless signal (I still had internet capability on this laptop also). In addition, my windows update will not be installed.  I checked "Event Viewer" in system tools and have all sorts of errors. Error service Control Manager, "Warning b57w2k", code error Windows Update Agent and more. Still, the laptop doesn't move and accesses files, but no internet. I scanned with AVG and Malwarebytes 0 infection. Uugh!  Any suggestions?

  Many laptops have a switch that turns on or off the wireless radio.  This can be a physical switch somewhere on the laptop or a combination of the Fn key and one of the F keys.  Read the user manual for the laptop for more details.

  The warning includes "b57w2k" seems to be linked to a Broadcom NetXtreme 57xx Gigabit Controller (not wireless, wired).  You can click the copy (just below the up/down arrows) on the property sheet for the event and paste the content in your next post here.

  In general, the report that you have 'all kinds of errors' in Event Viewer is not very useful.  We do not understand what you're watching.

• 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.

• 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.

  See you soon.

• Windows updates will not be installed. Windows media player will not play. Latest updates failed, error notice: 800703EE, 800b0100, 80070026. AVG says security "update server failed" help!

  Help! Last year, Internet Explore kept closing (Data Execution Prevention) so I switched to Firefox, which is great, but since then Windows media Player will not work. Moved this year on the campus of the University and since then (using the University proxy server) install windows updates is no longer. It's a new laptop me issued by the University last year, is come pre-programmed with Vista and Office, Media Direct and other programs, most of which I didn't use.  Technical support here at uni cant/wont help... can you?

  Trudy,
  Try the following and let us know the results.
  Run these tools:

  System File Checker

  The system update tool

  Take note of the results of the System File Checker.  Then after you run the two, run Windows Update.

  You are able to update of AVG?
  Any other antivirus (i.e. Norton, McAfee, etc.) has already been installed on this computer?
  When you say 'Nothing' that you tried to install?
  If you disable AVG and then run Windows Update you get a different outcome\error?

• 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 turn on

  I am told that Windows Defender has encountered a problem-0x800106ba. Said so to switch and restart, but to no avail. What then?

  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.
