I have installed it an hour ago and what I see so far isn't the lightest AV out there.
On scan, CPU usage goes up to 80% and remains.
On apps launch, CPU usage goes up to 17%.
On idle, there is a constant CPU usage going up and down, but it reaches 5-8% at times, which is also not the best I've seen.
On browsing, CPU usage is around 2-3%
Memory usage is about 410 megs.
I've taken screenshots of everything and might crop them and publish them later.
UI/UX and protection are great, but web blocking could be one idea better.
Whilst these values are not high, this is not different than any other AV. I'll leave it few more days before I conclude.
