Chapmike is more or less correct. You won't find any foolproof commercial antiviruses and most of them are indeed just 5% defense, 95% bloatware. If you are not sitting behind a multi-thousand dollar firewall and have a few hundred dollar/month subscription to services like Cisco Talos, your own computer/mobile with it's software will never grant 100% protection to you, especially if you are using free versions.
Windows Defender in it's own right is much better than it was years ago, but it's not really that excellent, especially since hackers would prioritize getting past Windows Defender first out of any virus-tracking software. That is the only thing making the reliance on it void.
Kaspersky is one I did really like and it was the least-bloaty software out there. However do keep in mind that it's speculated it sells data to Russia. I'm not saying it's 100 true and you should avoid it, but do keep it in mind that it's good to be cautious.
If I would really have to choose one, I would go with Malwarebytes currently, as that can root out some nasty stuff, but still, a well-coded virus might just be good enough to bypass it long enough to do damage.
I used through the years also: Avast (garbage), AVG (better than Avast and Norton, but still garbage now, it used to be pretty good though a long time ago), Norton (garbage). Basically do avoid any that is pushed in your face or on the "top" of most lists, they do like to pay a ton to be advertised.
For web-browsing, Ublock Origin is a must to have. Not only is it the best adblocker, but the best threat mitigator as well imo, two birds with one stone. It's also heavily modifiable for your own liking.
But honestly, your only best bet with everything said is to browse safely and download only trusted material. At the end of the day, know that the best defense you can have for your own device is your own sense and awareness.
