  1. Windows Defender closing Essential Program


    Hi there.


    I have been having troubles opening a program I need to file my taxes because I suspect Windows Defender terminates the program every time I open it. I would like to mention that the program is provided by our Bureau of Internal Revenue, and it contains the forms for filing taxes. The program can be found here. There are no other substitute programs for this purpose.


    I have successfully installed multiple versions of this program on my PC and they all have the same problem. If I attempt to run the program, even as Admin, the cursor will indicate a "loading animation" for 2 seconds, then nothing will happen. When I check the Task Manager to observe the program, it seem that Windows Defender activity goes from 0% to 0.3-0.8% in CPU activity every time I attempt to open the program. Otherwise, it just stays at 0%. So it seems that Windows Defender terminates this program before it opens.


    I would like to know how to prevent Windows Defender terminating this program. I tried to whitelist it by adding an exclusion in Windows Security, but nothing gets added on the list for some reason.


    Thanks in advance.

    :)

  2. Windows 10 Windows Defender versus Microsoft Security Essentials

    Hi Bryan,

    Microsoft Security Essentials was upgraded to Windows defender and it was a default security software from Windows 8. You cannot have both as they are one.

    Since you get this annoying popup at the startup i suggest you to disable any Microsoft Security Essentials entries in Startup tab.

    • Open the Task manager. by pressing Press CTRL+Shift+ESC.
    • click on Startup tab
    • Right click on Microsoft Security Essentials entry and click on Disable.

    Restart the computer and check if that helps.

  3. Security Essentials Windows Defender error 0x80070002 after upgrading to Windows 10

    windows defender is part of the windows 8/10 operating system now so should be on the c drive with the rest of the windows files. possibly when you upgraded security essentials came over with it and is conflicting. first I would make sure that security essentials
    or the old defender are not listed in programs and features. if they are listed run the uninstall. The built in defender will not be listed.

    Also try:

    • Stop Windows Update service
    • clear C:\Windows\Temp and %UserProfile%\AppData\Local\Temp
    • rename the C:\Windows\SoftwareDistribution folder to SoftwareDistribution.old (this will be recreated when you restart the service.
    • restart Windows Update service
    • try updating Windows Defender again

    Why did the startup window get cleared?

    I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.
