Pro Can install more components if you wish.
Optional installs include VPN, System Speedup, a password manager, browser extensions, and a hardened browser.

Pro Automatic updates for newly installed/ removed programs
Con Occasional pop-up ad in the taskbar
The ad is nagging the user to purchase Avira
Con Extras like Browser Safety include offers/deals when you're shopping
This is exactly the sort of behavior users want to prevent when using antivirus and similar security tools.
Con The notifications aren't very helpful
The notifications just pop up once. If you press the wrong button it's hard to go back and change your choice. And not all programs that connect to internet will trigger a notification.
Con Not very intuitive
The already included Windows Firewall is not very easy to set up. Although new rules might be set up very fast, it's hard to understand what's going on for normal users.
