We have a Windows Server 2008 Standard edition server and when we logged in today a service, McAfee Security Scan, had been installed. I checked all the logs, but can't find any trace of who or how this install was initiated. We already use Nod32 so there would be no reason for us to install McAfee.
Any idea how this happens?
I did look for other installs like Flash or the like, but didn't see anything.
