Hi there,
I am trying to install Avast on my Mac (MacOS 15.0 (24A335)), but I am getting the following error message " [Incompatible software detected Avira security software is already installed on your machine. Avast cannot be installed as it may not be compatible with your Avira security software".
There is no Avira software installed on my Mac at all.
Looking forward for some help and hints how I can solve this problem.
Cheers
It seems like Avast is detecting remnants of Avira software that may not be fully removed from your Mac. To solve this issue, start by checking for any leftover Avira files. Even if the software isn’t listed in your Applications, some residual files might remain. Next, try running Avast’s uninstaller if you’ve previously attempted an installation, as this will ensure there are no conflicting files left behind. Restart your Mac in Safe Mode to eliminate any potential software conflicts, and then attempt to reinstall Avast.
