It’s McAfee Security Center 7.0.331. I called into McAfee support on this a month or so ago and grilled them over and over asking for config settings to exclude directories or create user-defined extension exclusions. He repeatedly said its not possible with this product.
McAfee does have an enterprise product which likely does have group policies like you describe. But it seems they’ve dumbed down the features soo much for their consumer product, that they’ve hobbled it.
I’m experimenting now. I turned off heuristic scanning yesterday and it stayed running about 17 hours. I’ve restarted the service and am going to see how long it runs again. Then turn heuristics back on and see if it fails on the 2nd scan. Want to ensure it really is McAfee since the behavior did change yesterday.
