Microsoft Defender fails to update from File Share
Hello! I've tried to configure my Windows system to use Defender Updates through File Share. On my domain controller I've set two GPOs to make it possible. Define file shares for downloading security intelligence updates -> \\fileserver\DefenderUpdates Define the order of sources for downloading security intelligence updates -> FileShares When running the command Get-MpPreference I can see that the GPOs were successful with the following output: SignatureDefinitionUpdateFileSharesSources : \\fileserver\DefenderUpdates SignatureDisableUpdateOnStartupWithoutEngine : False SignatureFallbackOrder : FileShares The file structure on the file share looks like the following: \---DefenderUpdates \---x64 mpam-fe.exe Then I tried to run the command Update-MpSignature and I get the following error message: Update-MpSignature: Virtus and spyware definitions update was complated with errors. At line:1 char:1 + Update-MpSignature + + CategoryInfo : NotSpecified: <MSFT_MpSignature:ROOT\Microsoft\...SFT_MpSignature> [Update-Signature], CimException + FullyQualifiedErrorId : HRESULT 0x8024402c,Update-MpSignature This has worked previously but I don't know what has changed. Does any one have a clue? Best regards, dedicated-worker.
Unavailable/404 Windows update? "KB4580325: Security update for Adobe Flash Player (October 2020)"
Hello all, Ran across a couple PCs that were found to have a browser plugin vulnerability and "KB4580325" is needed to address it: KB4580325: Security update for Adobe Flash Player (October 2020) Problem is, there's a Microsoft KB link that takes you to a 404 page now and is no longer showing up when searching the Microsoft Update Catalog webpage either: https://support.microsoft.com/kb/4580325 Checking to see how others have addressed this type of situation where a KB is needed, but is no longer available to download. Thank you!
