Avira Free real-time protection using Smart Extension allows Avira to decide which files to scan based upon content.
Avira real-time should have been set to All Files to make a more equivalent comparison with Avast Hardened Mode. Although, I would not expect anything other than a minor improvement in detection - if any at all.
Still very nice review.
I really like Avira, but user cannot depend on it all by itself... free, paid or otherwise.
Thanks.
