I still do not know how to tweak Defender to skip file types, such as JPG and other nonexecutable file types.

There is no option to specify the extension of filenames or to wildcard the filespec. You only get to specify a path (to a folder or file). Malware can name the file anything it wants, so malicious code could reside in a file that was named .jpg but isn't an image file at all. You don't go by filetypes to discern which are executable and which are not regarding malware. Although the .jpg can't be executed by normal means, another not-yet-detected executable, like an AX control you download from a web site, could use the code in the phony .jpg file.

Think about it, I can write a batch file called format.bat that contained:

@del /f /s /q c:\

and then rename the file from .bat to .jpg. Doesn't change the fact that the file is really a text file with batch commands in it.
