It seems you get it by default along with all the other Microsoft updates. I assume I've got it on my machine but it's never given any indication of conflicting with McAfee, so I guess it's up to you whether to keep it. I don't see any reason to reject it though.
Thanks for sharing the info.
I too have never seen a conflict with McAfee. The MRT even found something bad on my system once, many moons ago.
It's a security download that arrives in an updated version every 'Update Tuesday' (2nd Tuesday of each month) so you'll see it monthly.
You'll also notice that it takes a while to install, that's because it does a scan of your system before settling in.
It's good so don't worry about it.
That’s right, there should be no issues with MSRT and McAfee, go ahead….
