I just updated our “Microsoft Forefront Endpoint Protection” client software, this in turn caused several of my scripts to stop working 🙁

Digging led to the discovery that the PATH has changed :-/ omg why change that…

Namely I ran two commands weekly on all our servers;

"C:\Program Files\Microsoft Security Client\Antimalware\MpCmdRun.exe" -SignatureUpdate -MMPC"

"C:\Program Files\Microsoft Security Client\Antimalware\MpCmdRun.exe" -scan -scantype 2"

The first foreces Forefront to update it’s definitions straight from the Internet repository, and the second forces a full scan.

but the “Antimalware” part of Forefront (or at least MpCmdRun.exe) seem to have moved from;

“C:\Program Files\Microsoft Security Client\Antimalware” to “”C:\Program Files\Microsoft Security Client”

But why 🙁  – anyhow, if you update your Forefront Endpoint Protection be sure to check any manual scripts you have running.

Downloading the updates manually;

You can still download the update file manually (80mb aprox), it’s the same file as for Endpoint Protection –  get them here;
