When I try to install Avast Free Antivirus it tells me it has encountered problems and even when I restart the PC the app is not installed. That is what it says in the installation log:

First of all, one reason may be (on Windows 11) that the protection of windows come in action.
To verify that you can start the installation with admin-rights (right-click on the file and choose “execute as admin”) to prevent.
Another reason can be, that the McAfee-Software isn´t uninstalled correctly for some reason.
If the first attempt doesn’t (with admin-rights) fails, than you can try to unistall the McAfee-Software by using the specialised Uninstall-Tool MCPR.exe from the official website under SupportTools/MCPR
and try again after restart.

I’ll hope, that it will help you.

Thank you. Yes, I’d already tried both workarounds. I was definitely in administrator mode and I had used the MCPR uninstall tool. But I still couldn’t install the free antivirus.
