• Windows Defender problem - does not open

  Dear Experts,

  Recently, I bought my computer with Windows Vista installed. It worked perfectly, but two days when I installed Microsoft Home Premium, McAfee licenced and registered all products including Windows online, I noticed that Windows Defender could not open by asking the following:

  «Failed to initialize: 0x800106ba.» A problem caused this program service stop. To start the service, restart your computer or search help and Support to find out how to start a service manually. »

  Please note that neither restarts nor search help has helped me solve this problem, whenever I turn on the laptop the session begins with the above given the message.

  Could you please provide me with the instruction on what I should do to fix this persistant problem with Windows Defender.

  Thank you very much in advance,

  Fuad

• Windows defender problems

  my windows defender program said I had to add definitions, but when I went to do this, he said that he could not add

  definitions

  Make sure that you are logged on as administrator.  If this is not the case, and try again.  That still does not work, start mode safe mode with networking (by clicking repeatedly on the F8 key during the boot process until the menu appears) and then try to do it from there.

  If none of these options work, please repost your question in the Windows Vista Security Forum to: http://social.answers.microsoft.com/Forums/en-US/vistasecurity/threads where the specialists of Vista Security (such as the impossibility of updating Defender) will be more than happy to help you with your problem.

• Windows defender can be uninstalled in Windows 8?

  I want to uninstall Windows Defender so that I can load System Mechanic Pro illo.

  If it is possible how uninstall you?

  Hello

  You cannot uninstall Windows Defender as it is an integral part of the operating system. It can be disabled in order for the 3rd part antivirus or firewall software to install.

  I installed Microsoft Office Home and Student 2010 on my computer Toshiba with Microsoft Windows and the first time I did it it went well through and Microsoft Click & Run and 2010 have been in my programs, but when I went to use my Windows program it came with a messeage of error that says:

The file may be read-only or may not be allowed to edit the file.    Then there is a box to check (OK) so I checked the box (OK) to see what happens & it looks like you're actually in Microsoft Office 2010, but once you go there comes another error message saying this:

  "Microsoft Office has encountered problems with the license and may have to close. If the problem persists, uninstall & reinstall your product.  Then, there is another box to check (OK) so I clicked on the box and then it stops and goes completely and so if you repeat this process did the same thing again and again.

  So I uinstalled just as he said and I've now done four times and still I get the same thing again and again. I also have can not uninstall Microsoft Click & Run when I try to uninstall it from my programs, it says contact Mircrosoft that I am unable to uninstall the package of Microsofts.  I'm the administrator of this computer and thought, I could uninstall and reinstall anything?

• I deleted Windows Defender on Windows Vista and tried to download and reinstall windows Defender but I gat a message that comes up saying that I should not install windows defender, because it came with the computer.

  deleted the windows on windows defender and impossible to reinstall! Message comes out and says that I should not install windows defender, because it came with windows vista. How can I try to fix it when I have windows Defender on my computer?

  You can not delete Defender in Vista.

  It is part of the Vista operating system.

  You can only activate / it:

  http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Defender-on-or-off

  Enable or disable the Windows Defender

  Many anti-virus have conflict Defender (McAfee, AVG, etc.), and turn it out / conflict with it.

  Microsoft Security Essentials, it turns off because it has its own version.

• MSASCui.exe bad Image... C:\Program Files/Windows Defender/Mp.Rt.Mon.DLL is not designed to run on Windows or it contains an error.

  Original title : A major problem with Windows Defender... will not run :(

  When I go to run Windows Defender, I get this message: MSASCui.exe bad Image... C:\Program Files/Windows Defender/Mp.Rt.Mon.DLL is not designed to run on Windows or it contains an error. Try to install the program by using the original installation media or contact your system administrator or the provider of software for support.  Then, after clicking OK, you get another small window saying "Windows Defender User Interface has stopped working... Search for an online solution and close the program (which does nothing) or close the program.    WHY?  McAfee scan says there is nothing wrong with the computer... There is something wrong. Impossible to get websites to find, or they are very slow.

  I have VISTA Home Basic edition, Emachine, bought 32 year THAT VISTA was released this January.

  That is to say 9 - seems to work better than 8 (which took awhile to do)

  SP2 is installed and I believe that most, if not all the updates are installed.

  Oh, and no matter what flash supported won't run... little is a nice way of saying. My flash player update. It is mess up until I had to update. :(

  Try the suggestion of Azam K.  If this help not to do the following:

  https://community.McAfee.com/message/208529

  McAfee should have disabled Windows Defender.  If not, or if you did turn back on, you must turn it off.  http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Defender-on-or-off   Windows Defender cannot be uninstalled from the Vista OS, but can be disabled to avoid conflict with other programs.

  You will probably need to uninstall Flash and reinstall it: http://www.adobe.com/support/flashplayer/

  I don't really like to make a negative comment on an anti-malware program, but McAfee has a reputation for sometimes bogged down operating systems.  If your problem persists, you will need to uninstall McAfee (to include using the McAfee removal tool) and see if that has any impact on your computer problems.  If there is an improvement, you may consider trying another program BC

• My Windows Defender has been damaged. I would like to install a more recent version.

  My Windows Defender does not work.  I tried everything, including playing with the registry.  Nothing helps.  Why Vista users cannot download newer versions of programs such as Defender?  Here's what I've tried: 1. I changed the permissions, 2. I disabled UAC, 3. I enabled it in the Task Manager, 4. I was able to make changes in the Configuration of the system, 5. I went in the tech blogs and tried their suggestions.  It was a big mistake.  I followed the advice of an "expert" and delete the values.  Now, instead of a message telling me that I don't have group permission, I have an error message telling me that the Defender has had a catastrophic mistake.   I even wrote down the original binary code, but it will not accept it.  I NEED A NEW WINDOWS DEFENDER NOW!

  In addition, you can't just re - install Windows Defender - he belongs to Vista and cannot be uninstalled or re-installed separately.  To re - install Windows Defender, you have to reinstall Vista itself.  You use an AV program that don't turn off Windows Defender and it still does not post then back with the name and version of the AV program you are currently using, and we will try to find the cause and a solution.

  I hope this helps.

  Good luck!

• I need to keep Windows Defender and Microsoft Security Essentials installed?

  My question is, what do I need to keep Windows Defender installed too, or I can uninstall it.

  I have Microsoft Security Essentials installed and it works fine. I am running Vista 64 bit with service PK. 2 and the Defender is installed under Vista. Before MSE I used Windows Live One Care until my subscription has expired and that they did not renew it. At that point, I finally installed MSE. Windows defender can be uninstalled? It seems to be an unnecessary element in my Security Center.

  Hello

  No it can't be uninstalled

  It is part of the vista operating system

  by default must disable MSE, it

  If for any reason any MSE has not disabled it read this;

  read the information on the below link on how to disable the windows defender service in vista or make an autostart to enable

  http://www.groovypost.com/HOWTO/Microsoft/Vista/disable-Windows-Defender-service-in-Windows-Server-2008-or-Vista/

  and here is the method to remove it from startup in vista

  http://www.groovypost.com/HOWTO/Microsoft/Vista/remove-Windows-Defender-from-Vista-system-startup/

  and this is how you would normally activate or disable windows defender in vista from within defenders of own and options tools

  http://www.groovypost.com/HOWTO/Microsoft/Vista/disable-Windows-Defender-for-Microsoft-Vista/

  and this is a very good Anti-Malware/spyware program to use in place of Defender

  an anti-virus can not find any problems

  you need to scan with a good anti-malware program

  Download update and scan with the free malwarebytes anti-malware version
