Bitdefender free may not be compatible completely but Bitdefender total security 2016 sure is. I have been using it 6 months now.
I don't go into firewall much, i let it do its job. It wasn't overly hard to add an item to whitelist the one time I have had to.
I have used most of the packages, I used to use Kapersky, Zonealarm, Avast, Norton.. most of big names except Macafee. Avast always asking for money, even on a paid version. Bitdefender just doesn't. that is why I like it... that and its so good at stopping infections.
