With all due respect, I feel the two options (default/express and custom) are plenty.
Any user who knows what they are doing should always choose the custom install.
Also never just click, click, click your way through any install. Read each and every screen
with great caution or you will be stuck wit something you don’t want.
Responsibility for ones computer is the user themselves.
edit: As for your statement, “Only protection shields are installed (Majority only needs protection shields)”,
I disagree, the “software updater” helps keep vital software up to date. The “browser cleanup” helps
keep browsers clear of useless toolbars and other junk. With “remote assistance” a user can assist
another user with their avast set-up. I could go on but you get my point.
