This happens during the installation process, and it's optional (it requires your consent). You can choose not to install Avast by pressing the Decline button. (see the screenshot).
3 important things about Avast antivirus:
1. We recommend you use Avast antivirus to protect your cybersecurity:
If you don't want it, you can uninstall it with CCleaner. Go to Tools > Uninstall. If you are still having trouble, please follow these instructions.
2. We don't offer Avast antivirus again if you already have it on your computer:
We can detect if you've installed the app on your computer. If we show the offer and you decline to install the app on your PC, we don't show the offer again for a fixed time.
3. You can install Avast on your machine from a previous CCleaner install:
If you don't want to do this, we give you the option to opt-out.
