I would be super grateful if someone from the community (or an Avast dev or support person) could confirm:ġ. I'm now trying to decide between attempting to run the installer again or ditching Avast completely. This is the polar opposite of my idea of a fun evening. Rather than go through the misery of trying to remove a broken/incomplete Avast install from my system, I wiped and re-imaged the hard drive. In fact, my experience yesterday has a lot of similarities with this forum post: The only other explanation for the installer's behaviour that I can think of is an incompatibility with Win 10 1909. I contacted Avast's support line via their UK number (08), but the T1 tech who I spoke to was unable or unwilling to check if anything was wrong with the update/download infrastructure. I was very worried by the installer's behaviour, and guessed that there might be an issue with Avast's servers - that's where the installer would be pulling files from, after all. No additional progress bar was displayed once the Avast UI loaded. When I have installed/re-installed Avast Premium Security or Internet Security in the past, the setup process has taken no longer than 10 minutes. When the Avast UI loaded, the 'Status' tab displayed the standard 'You're protected' message along with a progress bar and the words 'Completing installation'. The installation process took more than 90 minutes to setup and launch the Avast UI. I was using a clean install of Windows 10, updated to 1909.

I tried to install Avast Premium Security yesterday evening, using the online setup program from.
