Please download the TotalAV app by clicking on the Mac icon below, and then locate the downloaded TotalAV.dmg file from your ‘downloads’ folder (most likely in the downloads section of your browser) and open it. Alternatively use Finder to locate the installer. This will run the installation wizard which should complete in a matter of seconds.
Once the TotalAV software has been installed, it will require you to log in with your account email and password for your TotalAV account. The app will also update the virus definitions so you will need to make sure that you are connected to the internet.
