The PC security channel is good for newbies if it comes down to AV. But if you are looking for serious recommendations than you better do the research yourself. Why?
He only tests the programms on DEFAULT options. Meaning for most of the AV there is a high fail chance because they are built to not be intrusive and rely heavily on the user having a brain. If you are more advanced tweaking the AV program for example avast makes for a pretty damn good free protection.
The dude works for a AV company and is not neutral sadly. He also only uses simple and short testing methods.
most AV programs come down to your personal preferences. Like previously said if you are not a newbie than Windows Defender should be more as enough.
So in conclusion trying isn't good to really recommend a certain AV. The best is to say that one needs to do his own research and see for himself. I've used "AVAST!" free version for a pretty long time and for me as a lazy slack I like having the option to look for updates of 7zip or VLC it's handy and i can also freely see and tweak how strict the AV searches for threads and how to deal with it. If i had it on DEFAULT i would agree it's not "THE BEST" AV option.

Ugh and yes while AVAST!, Kaspersky and Bitdefender are pretty neat they come with your traditional spyware. And if you call me out on this, read their privacy policy or data conclusions. It's not enough to opt out of analytics sharing.

You can tweak it how you like and it uses Virustotal too. It tests all sort of malicious activities of programs, files etc.
The Sandbox even makes a screenshot of the Desktop+The uploaded Data so you can see what it does ^^
This one takes some time but is Free. You get some coins each day and can save up enough for the Chrono Pack but will take a couple weeks.
