Thank you, that was driving me crazy trying to figure out how to reproduce the block. On my system this block is fixed in 0.98, but from what I gather, it is still blocked on your system? If so, I can send you a special version of DefenderUI that will tell us exactly why it is still being blocked. So if it is still being blocked, please let me know and I will create a version to send you. Thank you!Regarding dismhost it occurs when I request disk cleaning, system files cleaning (for example when I want to delete old restore points)
But I did not understand the issue discussed about tamper protection. I have DUI Pro in the recommended mode, tamper protection enabled and the only feature which does not work with tamper protection enabled is Threat Default action. Thank you!
