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.
ClamAV is fine as an AV. (Albeit, Designed for mail.)
As long as you aren’t downloading anyting stupid, you should be fine.
Plus, Common Sense is the best AV.
