No mention of how many false positives the anti virus programs give, I would imagine that the table would be up sided down, also MSE scores the highest for useability, which is why I use MSE, hassle free and ease of use.
I've used Kaspersky for years, and the only times I need to even go near the software is when I want to. The firewall is very smart about my needs, and for those times when I end up getting ads with driveby kits in them(in spite of adblock), it pops up to let me know that some piece of @#$% just tried to screw with me and failed, then slides out of sight.
I guess, I can see that when I do delve into the menus it can be a little circular maybe, but we're all adults here, we can click on things that sound like they're what we're looking for. So usability is a bit of a crock, imo.
It's all well and good that so many people here seem to think that security essensials is all you'll ever need and all, because who clicks on dumb stuff anyways, but while you can exclusively use a browser with scriptblock and adblock and never see a compromising link in your life, you cannot guaruntee the same for your spouse/children/parents/relatives.
There are ignorant people using the internet, and they would like to continue being able to do so without needing to get a certification in itsec. Stop claiming that MS Defender is all you'll ever need since you're only serving to mislead people into thinking it's a viable solution.
