HI Doug,

I agree with you that Defender is the issue. The latest windows update seems to be the trigger from what I have seen.

I did the reinstall last yesterday, and the backup worked, but later the dll was again quarantined. I am not sure if the file was "killed" from this same workstation or another one as I am not 100% confident the IT group had setup up the exclusions correctly on the second workstation. I again reinstalled and cleaned up the exclusions and so far so good.

Is this file going to be white listed going forward?
