System resource usage just too damn high... You won't see the CPU usage spikes from that screenshot, but I saw multiple times over 40% CPU usage from a2aservice.exe process which is really unacceptable, no matter how you look at it. That would choke lower core count CPU. I've never seen AV use over 1.7GB of RAM before. Been a while I tried Bitdefender last time, but I suspect its the Bitdefender engine just getting more and more absurdly demanding. Yes, it has good behavior blocker. It doesn't have bad protection. But there are others that use significantly less resources and provide equal or better protection... Your security software should not be using this much resources imo. Still, I'll give it 3 stars and that's me being generous. After all, there are much worse products out there too. I just would not use it personally.
