I am just a beginner in minifilter development. I am working on MSDN sample AVscan. Now the target OS of this sample is Win8 or above. Is it possible to compile AVScan Minifilter https://code.msdn.microsoft.com/windowshardware/AvScan-File-System-40053812#content given in the MSDN Sample for Windows 7? I am using Visual Studio 2013 with WDK 8.1, the sample project don’t have Win7 Debug/Release in the configuration manager. if it is possible how can it be done? Kindly guide me

I would start with “Scanner File System Minifilter Driver” sample. Much
smaller and easier to understand.

Now the target OS of this sample is Win8 or above. Is it possible to
compile AVScan Minifilter
Just compiled it, executable didn’t start because of UnmapViewOfFileEx
function. Driver is less likely to be incompatible.

@Dogan Kurt for your kind response

Just compiled it, executable didn’t start because of UnmapViewOfFileEx function.
Driver is less likely to be incompatible.

so if I want to have such driver for Win7, I have to rewrite it?

Not only the executable fails to start but also the driver fails to load with error msg, specified procedure not found

Yup. Don’t use UnmapViewOfFileEx.
