My lastest post wasn't so good, I'll try to give you more details.
I tested a lot Bitdefender, and if you set the IDS and the AVC on maximum. It almost block all malware. But like all antivirus it can't be perfect.
Some people here are saying that Bitdefender is heavy but I don't think they tested it so long, after one or two week we can really see how Bitdefender Photon is working well

If you don't like Bitdefender just beacause he's to quiet, don't be in autopilot mode.
For me the bitdefender firewall is a lot better than emsisoft firewall.
No changelog for bitdefender, I don't think they care about community.
On maximum setting I don't know how can you be infected with bitdefender, maybe if you're unlucky or you're clicking everywhere.
Emsisoft has a great support, their devs are kind.
Emsisoft Interrnet Security can sometimes be buggy. And it's incompatible with Virtualbox.
Emsisoft is good as Bitdefender. Maybe a little lighter but personally I don't feel much the difference.
If we talk about privacy I trust more Emsisoft too.
Like Infamous, I think you should just test both, and see what you prefer. But don't forget Photon, it works start working one week after the installation.
