Hyper-V Beta/RC tip of the day - exclude .VHD and .AVHD files from AV scanning

Make sure you exclude .VHD, and .AVHD files from being scanned because it can and will cause file lock issues/contention between your AV scanner and/or the Hyper-V services.

Ditto can be said for VMWare .vmdk files.

Some people are running into this issue with the new Hyper-V beta and it will error out with an error that will not typically lead you down this path while debugging the problem.

For instance on my external drive, I have a folder named "Virtual Machines" and I exclude the whole directory tree. That might be a bit excessive but it tends to prevent problems.
