Today the Windows Defender Antimalware Platform was updated automatically from version 4.18.2011.6 -> 4.18.2101.4 on my computer.
I didn't notice it at first but since this morning I was experiencing the following problems on my computer:
- LDAP queries to the domain controllers took a long time
- Opening the Active Directory Users & Computers MMC add-in took a very long time and when opening the OUs,
the MMC console stopped responding. Also when choosing to change the domain controllers, the domain controllers were not populated.
- Group policy updates were very slow (from 4 seconds on normal computer to more than 2 minutes on my affected computer)
I was searching almost the whole day with group policy debugging and LDAP network sniffing because I thought that it was a
problem with the domain controllers. (I installed the monthly security updates this weekend on them)
When I reviewed my event viewer once more, I saw the information message from this morning that the antimalware platform was updated.
After reverting to the previous version with "%programdata%\microsoft\windows defender\platform\<version>\mpcmdrun.exe" -revertplatform
the problems suddenly disappeared.
Anyone else experiencing problems with this update?
