To show it really works. When the installer hangs at 94%: The first time, I forcibly halted the mac using the power button. This is not really a good idea: after that, KIS complained there are some missing modules. It is still possible to launch it then uninstall it to start over. The second time, it worked for me. However, I was hacking a bit. I am not sure whether it worked by itself of if it were my hacking activity that unfroze the installer. Namely, in a terminal, I lauched the script that was hung, looking for the step at which it actually hung. But in the meanwhile, the installer resumed and completed successfully. For me, it was: "cd /tmp/PKInstallSandbox.2seyCw/Scripts/com.kaspersky.kav.core.CFsDP9 && sudo ./postinstall". And now, everything works well for me. This is my experience. Hope it helps.

Hi. No issue... I installed KIS 20 on macOS Catalina last Wednesday, right after OS update. And it works quite well The screenshot you have made is not new to Catalina: double-finger-clic to enable the 3rd option to bypass Apple's check, as usual. By the way, installation's last step "executing script" takes some time and is a bit capricious. But once the step passes, everythings is fine.
