> I've experienced a bug related to the on-disk real-time scanning of Windows Defender, but instead with 100% disk bandwidth usage for unreasonable amounts of time.

Sophos does this on my work laptop with depressing regularity. At this point I just go grab coffee when the fans max out, cause I know the disk is similarly pegged and it'll be about as snappy as a bogged down Windows 98 machine until it finishes.

I experience the same issue on my laptop, and I've come to think it might be everytime the memory got swapped out. Sophos seems to interfere when the memory is read back from disk, which is annoying and frustrating.
