Antivirus

Forgot to ask this in my excitement about the new laptop, but does anyone have any advice about what's the best free antivirus out there? I used Avira on my old one but all the Doom and Gloom Buy Our Pro-Version popups got really annoying. I have an adblocker installed on my browsers and no coin, but a good antivirus is important too. The laptop came with McAfee installed but I remember hearing meh things about it so I'd like to switch to something that's recommended (and recommended by people who actually use it and not blog posts/articles of possibly being paid to say certain things nature).

What do you all use? Do you like it?
