Question: System Extension Blocked

I am trying to install Kaspersky AntiVirus on my mac, but I am unable to.

I get a System Extension Block with two choice Open Security Preferences and OK.

Clicking OK I get another System Extension Block popup until I get plenty that fill my screen.

Clicking Open Security Preferences, I have two options App Store and App Store and identified developers. I have the App Store and identified developers.

I thought that when installing an app I should be able to select OK from this screen but I do not. I have tried various command line "fixes" via terminal but they do not seem to work. This is the first time in years that I have been pulling my hair out with a mac. Normally, everything simply works.

MacOS High Sierra Version 10.13.3

It is a good thing that Kaspersky AntiVirus is being blocked. Your computer is trying to protect you. Kaspersky and other anti virus apps are not needed and they may cause issues.
