Unable to install Avast Premium on Big Sur

Has anyone managed to install Avast Security Premium on Big Sur? It fails to install for me. I've tried enabling the latest version under System Preferences, but there's nothing to enable, since it doesn't install. The free version installs and works fine, however.

MacBook Pro 15″, OS X 10.10

There are no known Viruses in the wild that self replicate and affect macOS. There are Malware and Adware that does affect macOS and are often times downloaded as part of an Application from Third Party UnTrusted Site and get installed along with the Application. For Adware of Malware - Suggest downloading from a Trusted Developer and Respected ASC Contributor the application Malwarebytes for Mac. It is free or paid for added features. Run the Application and it should remove the malware / adware. Once done, restart computer and test


Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation. The Built-in Security of Big Sur is all that is required.
