McAfee and Norton have each had issues with some updates incompatible with a Windows update, resulting in a non-bootable system, however, to say that "any AV other than MSSE/Defender will crash the system' seems a bit of a stretch, and, in my opinion, is a jaded opinion.
(Maybe the aforementioned systems crashing had nothing to do with the chosen AV? Numerous possibilities exist, but, to decide the AV was the cause, one could just as easily blamed Intel, AMD, HP, Dell, or, Asus, etc., depending on the chosen components in the build)
