Microsoft Security Essentials not updating - MBAM

Recommended Posts

Hmm, that's odd.
I don't recall seeing this reported before: MBAM Self-Protection (SP) preventing MSE from updating.

Let's start with some routine troubleshooting.

When you perform the MBAM clean reinstall suggested in step #1 below, please be sure to do so from an Admin-level Windows user account.

Also, it might help to set mutual exclusions between MBAM and MSE. 
The attached screenshot shows an example (with a different AV product, KIS, not MSE) of how to exclude MSE from MBAM.
The instructions at the bottom of this reply list the MBAM files to exclude in MSE.

  1. Please uninstall your current version of MBAM and reinstall the latest build - MBAM Clean Removal Process 2x
  2. If that does not correct the issue, then please read the following and post back attached to your next reply the 3 requested logs - Diagnostic Logs
  3. NOTE: There is an FAQ section with valuable information located here - Common Questions, Issues, and their Solutions

Please post back and let us know how it goes.



 Please exclude the following files from your Antivirus Software for your version of Windows:

For 32 bit versions of Windows XP, Windows Vista, Windows 7 & Windows 8:

  • C:\Program Files\Malwarebytes Anti-Malware\mbam.exe
  • C:\Program Files\Malwarebytes Anti-Malware\mbamdor.exe
  • C:\Program Files\Malwarebytes Anti-Malware\mbampt.exe
  • C:\Program Files\Malwarebytes Anti-Malware\mbamservice.exe
  • C:\Program Files\Malwarebytes Anti-Malware\mbamscheduler.exe
  • For 64 bit versions of Windows Vista or Windows 7 & 8:
    • C:\Program Files (x86)\Malwarebytes Anti-Malware\mbam.exe
    • C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamdor.exe
    • C:\Program Files (x86)\Malwarebytes Anti-Malware\mbampt.exe
    • C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamservice.exe
    • C:\Program Files (x86)\Malwarebytes Anti-Malware \mbamscheduler.exe
    Note: If you are using a software firewall besides the built in Windows Firewall, you'll need to exclude MBAM.EXE and MBAMSERVICE.EXE from it as well.

    Note: Once that's done, please make sure that if either of those programs has any sort of web filter, that you add the following as a trusted site:
    The FAQ contains examples of setting file exclusions for some known AV products; it is rather outdated, but the general approach still applies.

That's pretty interesting,

MSE updates come to users via the windows update system,

So this is pretty wacky,

I personally do not load Optional windows updates automatically too much other junk come via the same category so this is not testable but the entries I have excluded in mbam for MSE are these I have a 64 bit machine so MSE is in both program files and x86 program files as Microsoft security client,


Being a Windows update is being blocked I would know what to exclude :D


Manually updating MSE and loading the Optional updates are not being blocked on my end "Yet"

Good topic though,
