I see that Bitdefender came out on top as golden boy for 2014.
Here's a list of features in the free version
Bitdefender Antivirus Free Edition Features - Bitdefender Forum
I have to ask myself, if this is so good then how come I'm not using it?
I'm wondering if the free version uses the same engine/definitions as the paid version, though. That's what I'm most concerned about.
I just use the built-in Windows Defender since I watch what I click. For my parents/clients though...I put a 3rd party AV on their systems.
