What antivirus software should i use?

It's been a long while since i used a desktop and honestly can't remember what antivirus software i used, and even then, probably the landscape has changed over the years.

Atm i've been winging it with just Windows Defender (no custom configuration) and scanning any thing that looks suspicious on VirusTotal, but probably that would be not enough.

I'm thinking on get a couple of pirated files, so i'd like to be as secure as possible.
