This is not going to be in depth at all, but I thought it would be of interest here, since we always talk about AV programs.
I recently have decided to change my AV software. I just started using ESET NOD32 (AV only) yesterday, and I think that's the one I prefer, let me explain.
I used to use Kaspersky, like a decade ago. It was good, but then it started slowing down and being "unresponsive". Like, I'd click on buttons like update, or other ones (don't remember), and nothing would happen, or it would take many seconds. it was pretty annoying, I hate that. So it was a performance issue, it seemed to be slowing down enough to bother me.
That's when MSE was getting a lot of publicity. I tried it...it was free, fast, not bad. So I kept that for a few years until last year.
I got annoyed by the lack of options in MSE, like being able to exclude files and folders with an interface that I liked. So I started looking at the options again. I tried Bitdefender. It was good, very simple and pretty fast. I used it for a while, but then the exclusion interface also started bugging me. I just don't like it. I also don't like how overly simple it is, almost the same complaint as MSE.
Then I tried Kaspersky again, after a few years. Well, it has also suffered from interface annoying things. Whereas before, all the options were in a nice simple tree, etc. now they are all over the place. Like ribbon interfaces, you have to click around to find what you want, very annoying. But it is loaded with features, pretty fast I guess. But the interface was bugging me.
So I tried mouser's favorite, NOD32. I like it! The first thing I noticed was all the options are in a nice dialog with a tree interface. None of this modern, weird, uber simple stuff.
So that's it. ESET has hit the sweet spot. Hopefully it's not too slow or something.
