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.
