Windows Defender Service stops working

Randomly, the service for Windows Defender stops working. I set it to auto restart, but it does this often. I'm currently running a virus scan with malwarebytes to see if it's that kind of problem. Any ideas as to what may be causing this?

  1. Just disable Defender, switch Microsoft Security Essentials, far better.
  2. Microsoft Security Essentials cannot be installed on Windows 8, as it is "apart" of Windows defender.

    I've looked into the event viewer and have found that I am getting Error ID 7031 and 7034, which are related to Windows Defender services unexpectedly closing. I've also may have a problem with my Windows Updates where I have not had an update specifically for Windows 8 since 1/9/2013.

    @Reese227
    My system has the same symptoms (I don't know about the Error ID's yet)
    Did you find a solution to this problem?
  4. Same problem.
    The Windows Defender Service service terminated unexpectedly. It has done this 6 time(s).

    Faulting application name: MsMpEng.exe, version: 4.0.9200.16384, time stamp: 0x5010a938
    Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000
    Exception code: 0xc0000005
    Fault offset: 0x000000afa0946af2
    Faulting process id: 0x25a8
    Faulting application start time: 0x01ce1d2459216cf9
    Faulting application path: C:\Program Files\Windows Defender\MsMpEng.exe
  5. Found another instance mentioning the same problem at Microsoft technet (apparently with a Windows server)

    No solution though.

    Do you have Microsoft Security Essentials installed? If so, it disables Windows Defender and turns off it's service since it replaces it.
