Avast Permier blocking image write to sd card

I have been trying for several hours to write a Linux (Stretch) image to an SD Card with Win32diskimager. I am running WIndows 10 64-bit, currently updated. No matter what I try, including turning off all shields, I keep getting an error 5 access denied message when I attempt to write the image.

Why am I getting these messages, even with ALL SHIELDS off?

Thanks.

Why do you think Avast is blocking it…!? Post a screenshot.
