On a whim, I deleted all of the files out of the %windir%\serviceprofiles\LocalSystem\AppData directory - not that any looked out of the ordinary - and now when I restart the server, the message I was getting has stopped happening. I couldn't find any reference to the directory or any files in it in a Process Monitor boot log. I feel *slightly* better that the message has gone away - but not really much, because it seems like some kind of infection, or attempted infection, has crawled under the radar. I might take one of these systems out and run a full scan from an alternative OS as suggested, but I hate the nagging feeling that something has gotten away without being fully understood. I'm hoping my strategy of AV + whitelisting hasn't led to any compromise, but I'm still wondering whether I should initiate a full rebuild of the server farm.

According to it, everything is hunky-dory. MalwareBytes didn't detect anything on a full scan either. I'm pulling up some Process Monitor logs now to see if there are any needles in that haystack.

By the time I get to checking for them, they are gone. The reason I know they are there is because my whitelisting application doesn't allow executable content to have its ownership overwritten, and when the servers boot up, they are logging an event regarding an attempted ownership overwrite AppSense Application Manager intercepted the overwrite of the allowed executable 'c:\windows\serviceprofiles\localservice\appdata\local\temp\random_8_cha racter_filename.dll' on ''servername'. Ownership of this file was changed to that of the user I've never noticed this happening before, and the randomised filename screams "malware" at me - but I have scanned the system with Trend and MalwareBytes, and can find no trace of any infection. By the time I dig into the folder to check, there's nothing there. Does anyone have any idea why these files would be appearing at boot time? My next step is to break out a bit of Process Monitor, but I'm just wondering if I am barking up a false positive tree here.
