[Unexpected - KIS 2019 updated to KIS 2020 automatically]

Hi Flood, to confirm I have been using Kis Total Security and Malwarebytes in Real time, since Malwarebytes came up with an update to fix the various compatibility issues, no problems for me on 3 machines since? 

[Malwarebytes compatibility with Kaspersky]

I cannot believe: I formatted my Windows just because of this problem. I though my Windows files are broken.

Then I used my new Windows with using Malwarebytes only for one week without any problem. Today I decided to setup Kaspersky too. After setup (I didn’t uninstall MBAM of course, I always use KIS and MBAM together for years), every little bug and problem showed up again.
So I decided to search conflict about KIS and MBAM, and here I am. The problem was never related to my Windows 😞

I will chose this method:
Uninstall KIS 2020 and setup KIS 2019.

Apparently Malwarebytes have fixed the compatibility issue.

If Malwarebytes components package 1.0.854 is installed, you should not experience the conflict with Ransomware Protection after installing Kaspersky Internet Security 2020.
