This just started recently, within the last week or so. I’ve confirmed the behavior on all 3 Windows 10 PCs I have, and get roughly one complaint per day from potential customers now. The download will complete as normal, but then gets stalled for 5 to 15 MINUTES while Defender does its work. In Edge, it at least says “Running Security Scan” but Chrome just looks like it’s sitting there.
This one has me stumped. I thought it might be just my newer builds or just Windows 1903, but it also happens with all my builds and one of my test machines is still on 1809.
Does anybody have any ideas? If you want to try it out, just download my app from https://beaconapp.cc/download - there is a large button right in the middle. This is very frustrating, and Google hasn’t been much help.
