I'm using W10's Defender, and Opera VPN when I feel the need. I have yet to find any virus or malware in a few years.
Can I ask if you are visiting bad sites and downloading Torrents? That requires a level of protection that isn't known yet. It's that dangerous.
I am using currently Avast free and Malwarebytes. What else could I add with that? Adguard addon in browser?
