windows defender was one of the (many) reasons I gave up on windows and replaced the last windows machine I had with a Mac Mini. (FC33 on my main)
Very similar experience here, coupled with windows defender randomly switching itself back on and quaranteening half my (completely benign) development folder.
The last time it did that I spent an entire afternoon trying to get it disabled and get my files back onto the machine with only limited success.
I think it may be a windows home vs windows professional thing.
But rather than wrestle with it further I just gave up. Only thing I had left that really needed windows was word and excel which ironically actually now work better and crash less on the mac mini than they ever did on windows.
