Pros
Pro Fast and effective
Pro Thorough and detailed descriptions
May take a while if you have a lot of files and a large registry, but it's worth the wait.
Pro Fast, and free version seems powerful
I've used AVG Free in the past, and it seemed to slow my computer more than Avira does.
Pro Can install more components if you wish.
Optional installs include VPN, System Speedup, a password manager, browser extensions, and a hardened browser.
In the case that you've downloaded the Free Suite (not recomended), you can uninstall the above mentioned additional downloads with Avira's Connect app or any uninstaller utility software. This flexibility to cherry pick your extra software keeps the bloatware down somewhat.
Cons
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.
