At this point, click on the button Yes, wait a few seconds for all the antivirus files to be prepared and choose whether to install too Avast Secure Browser (a browser customized by Avast, which however is not essential for the protection of the PC or online browsing) by keeping or removing the check from the appropriate box at the bottom left.
