Im manually updating Malware  agent, with Update-Engines.ps1 script.

Should I include all engines or are all required, or I should use  only Microsoft Engine

Flowing are options for  defining a specific engine(s) update : Microsoft, Command, VBuster, Kaspersky, Norman, Wormlist, Cloudmark

Hi,

Absolutely yes.
Engines list:
X86: Microsoft, Command, VBuster, Kaspersky, Norman, Wormlist
AMD64: Microsoft, Command, VBuster, Kaspersky, Norman, Wormlist, Cloudmark

If run Update-Engines.ps1 without engines parameter, all engines will be downloaded for both the 32-bit and 64-bit platforms.
We can run this command with customize engine to update, for example:

Update-Engines.ps1 -EngineDirPath C:\ScanEngineUpdates\ -UpdatePathUrl http://forefrontdl.microsoft.com/server/scanengineupdate -Engines Microsoft -Platforms amd64, x86

Hi,

Do you have deploy multiple scan engines?
If not, please refer to below link to configure: https://technet.microsoft.com/en-us/library/bb795072.aspx
